7-Step Guide to How CIOs and CISOs Can Achieve Successful SASE PoCs

In IT decision-making, Proofs of Concept (PoCs) serve as a critical evaluation tool for organizations assessing new technologies before making full-scale investments. PoCs allow CIOs and CISOs to validate whether a solution meets their technical, security, and business needs in a controlled environment, reducing the risks associated with large-scale rollouts.

By providing hands-on experience with a technology, PoCs help IT leaders make informed choices, ensuring that the selected solutions align with their organization’s long-term strategic goals.

However, traditional PoCs, especially for legacy networking and security tools, often introduce more complexity than clarity. Legacy PoCs are typically siloed, time-consuming, and resource-intensive, requiring organizations to test separate security and networking products in different environments. This fragmented approach leads to lengthy evaluation cycles, excessive use of IT personnel, and unclear outcomes, making it difficult for CIOs and CISOs to gain confidence in their investment decisions.

One of the biggest challenges with traditional PoCs is the lack of measurable, business-driven outcomes. Many legacy PoCs focus purely on technical feasibility rather than demonstrating clear business value, such as cost savings, operational efficiencies, or security risk reduction. As a result, organizations may struggle to justify their investments, leading to stalled decision-making and, in some cases, failed projects.

Moreover, the need for complex hardware installations, configuration changes, and multi-vendor integration further slows the process, increasing the likelihood of pilot fatigue—where stakeholders lose momentum before reaching a decision.

This is where SASE (Secure Access Service Edge) PoCs stand apart. Unlike traditional PoCs that evaluate security and networking tools separately, a SASE PoC offers a unified, cloud-native approach, converging networking and security into a single, streamlined evaluation. By testing a fully integrated platform, CIOs and CISOs can assess how well the solution delivers secure, optimized, and scalable connectivity for today’s cloud-first enterprises.

A well-executed SASE PoC provides measurable results tied directly to business value—demonstrating improvements in security posture, network performance, and operational efficiency. Instead of lengthy, uncertain evaluations, SASE PoCs enable faster, data-driven decision-making that reduces risks and accelerates time-to-value.

Organizations can quickly determine whether the solution aligns with their security and networking needs, making it easier to secure stakeholder buy-in and transition to full deployment.

This guide will walk CIOs and CISOs through a 7-step framework to conducting a successful SASE PoC, ensuring they gain the clarity, confidence, and actionable insights needed to make the right technology investment.

We now discuss the seven key steps to achieving a successful SASE PoC.

Step 1: Define Clear Business and Security Objectives

Conducting a successful SASE (Secure Access Service Edge) Proof of Concept (PoC) begins with defining clear business and security objectives. Without well-articulated goals, PoCs risk becoming disorganized, unfocused, and ultimately inconclusive.

CIOs and CISOs must ensure that the PoC aligns with their organization’s broader business strategy, security requirements, and digital transformation initiatives. This alignment is critical because the primary goal of a SASE PoC is not just to validate technical feasibility, but also to demonstrate how the solution contributes to overall business efficiency, security resilience, and operational agility.

Aligning PoC Goals with Business Needs

Every organization has unique business needs that drive IT investments. CIOs and CISOs should begin by identifying the key challenges that a SASE solution is expected to address. Common business drivers for adopting SASE include:

• Reducing IT complexity by consolidating multiple security and networking tools into a single, cloud-native service.
• Enabling secure remote workforces by providing seamless and secure access to cloud and on-premises resources.
• Improving network performance by optimizing connectivity and reducing latency for critical applications.
• Reducing costs by eliminating expensive legacy hardware and reducing reliance on MPLS (Multiprotocol Label Switching).
• Enhancing security posture by enforcing Zero Trust principles, reducing attack surfaces, and improving threat detection capabilities.

By tying PoC objectives to these business needs, CIOs and CISOs can ensure that the evaluation process remains focused on delivering measurable, strategic outcomes rather than getting lost in unnecessary technical details.

Aligning PoC Goals with Security Requirements

Security is at the heart of any SASE implementation. Before initiating a PoC, organizations must clearly define the security challenges they want to address. Common security objectives include:

• Enforcing Zero Trust policies to prevent unauthorized access and lateral movement within the network.
• Reducing exposure to advanced threats such as ransomware, phishing, and supply chain attacks.
• Ensuring compliance with industry regulations like GDPR, HIPAA, and PCI-DSS.
• Simplifying security management by integrating multiple security functions (firewall, CASB, SWG, ZTNA) into a unified platform.
• Enhancing visibility into network traffic, user behavior, and potential security threats.

By establishing clear security objectives, organizations can design PoC test cases that specifically validate whether a SASE solution meets these requirements.

Integrating Digital Transformation Initiatives

Modern enterprises are undergoing rapid digital transformation, and IT leaders must ensure that any new technology investment aligns with their cloud adoption strategy, remote work initiatives, and DevOps-driven environments. SASE plays a crucial role in digital transformation by:

• Providing secure cloud connectivity for SaaS applications, multi-cloud environments, and hybrid infrastructures.
• Enabling secure DevOps by enforcing security policies without slowing down development pipelines.
• Facilitating network modernization by replacing legacy WAN architectures with a more agile, cloud-native model.

By framing the PoC within the broader context of digital transformation, CIOs and CISOs can demonstrate how SASE supports long-term business growth and IT innovation.

Identifying Key Metrics for Success

Once the business, security, and digital transformation objectives are defined, the next step is to establish key performance indicators (KPIs) that will determine the success of the PoC. These KPIs should be quantifiable, relevant, and directly linked to business outcomes. Common success metrics include:

• Cost reduction: Measuring reductions in IT operational costs, MPLS expenses, and hardware infrastructure costs.
• Improved network performance: Assessing factors like reduced latency, faster application access, and optimized bandwidth utilization.
• Enhanced security posture: Evaluating metrics such as reduced phishing incidents, lower mean time to detect/respond (MTTD/MTTR), and increased compliance scores.
• Operational efficiency: Measuring the reduction in IT workload, improved policy management, and automation-driven time savings.
• User experience improvements: Monitoring end-user satisfaction through latency reduction, improved remote work experience, and application performance enhancements.

By defining these clear, measurable success criteria, CIOs and CISOs can ensure that the PoC produces actionable insights that support an informed decision-making process.

Ensuring Stakeholder Alignment

A well-defined PoC requires buy-in from all relevant stakeholders, including IT, security, networking, and business teams. Each stakeholder group will have different priorities:

• Business leaders will focus on cost savings, ROI, and how SASE aligns with strategic initiatives.
• Security teams will prioritize risk reduction, Zero Trust implementation, and compliance enforcement.
• Networking teams will evaluate performance, latency, and connectivity improvements.
• IT operations will consider ease of deployment, automation, and long-term manageability.

To ensure a successful PoC, CIOs and CISOs should facilitate cross-functional collaboration, ensuring that all stakeholders contribute to defining objectives and success metrics. This alignment prevents future conflicts and ensures that the PoC’s results are relevant to all decision-makers.

Creating a Structured PoC Roadmap

Before moving forward with vendor selection and testing, CIOs and CISOs should create a structured roadmap outlining:

1. Primary PoC goals: What business and security challenges are being addressed?
2. Key success metrics: What specific KPIs will determine whether the PoC is successful?
3. Stakeholder responsibilities: Who will be involved in testing, evaluation, and decision-making?
4. Evaluation timeline: What is the expected timeframe for completing the PoC?
5. Expected deliverables: What kind of reports, insights, and recommendations should come from the PoC?

This structured approach prevents scope creep, ensures accountability, and keeps the PoC focused on delivering real business value.

Defining clear business and security objectives is the foundation of a successful SASE PoC. By aligning goals with business needs, security requirements, and digital transformation initiatives, organizations can ensure that their evaluation process remains strategic and outcome-driven. Establishing measurable success metrics and securing stakeholder alignment further strengthens the PoC, providing a clear framework for decision-making.

With well-defined objectives in place, the next step is to establish success criteria and measurable KPIs.

Step 2: Establish Success Criteria and Measurable KPIs

After defining clear business and security objectives, the next critical step in a successful SASE PoC is to establish success criteria and measurable Key Performance Indicators (KPIs). Without well-defined success metrics, PoCs can become subjective and inconclusive, leading to uncertainty, delays, and wasted resources.

CIOs and CISOs must differentiate between technical validation and business value, ensuring that the PoC provides quantifiable evidence of how SASE improves network security, performance, and operational efficiency.

Why Defining Success Criteria Matters

In many IT PoCs, organizations focus too much on basic technical validation—verifying whether a solution functions in a test environment—without linking it to real business impact. This approach often results in ambiguous outcomes that make it difficult to determine whether the solution is worth a full-scale deployment.

By contrast, a SASE PoC must go beyond technical functionality and demonstrate:

1. Operational efficiency improvements (e.g., reduced IT workload, simplified management).
2. Security posture enhancements (e.g., stronger Zero Trust enforcement, reduced cyber threats).
3. Network performance benefits (e.g., lower latency, optimized cloud access).
4. Cost savings and ROI (e.g., lower MPLS costs, reduced hardware dependency).

By establishing clear success criteria, CIOs and CISOs can ensure that the PoC delivers meaningful insights that support data-driven decision-making.

Defining Measurable KPIs for a SASE PoC

A successful PoC should include quantifiable, objective metrics that provide a clear comparison between the organization’s current networking and security state and the projected benefits of a SASE solution. Below are some key categories and KPIs to track during the PoC.

1. Network Performance and User Experience KPIs

One of the primary goals of SASE is to optimize connectivity while improving security. The PoC should measure whether the solution reduces latency, accelerates cloud access, and enhances user experience for both on-premises and remote users.

Key Metrics to Track:

• Latency reduction: Measure before-and-after latency for key applications (e.g., SaaS, VoIP, video conferencing).
• Cloud application performance: Assess how well users can access cloud-based services like Microsoft 365, Salesforce, and AWS.
• Bandwidth utilization: Analyze how efficiently network bandwidth is used compared to legacy solutions.
• Remote workforce connectivity: Measure VPN-less access performance using Zero Trust Network Access (ZTNA).

Example KPI:

• Reduce average latency for critical applications by at least 30% compared to the existing WAN infrastructure.

2. Security Effectiveness KPIs

A core function of SASE is to improve security while reducing complexity. The PoC should evaluate whether the solution strengthens threat detection, enforces Zero Trust, and simplifies security operations.

Key Metrics to Track:

• Threat detection and prevention rates: How many threats are blocked in real time?

• Phishing and malware protection efficacy: Measure detection and blocking rates for phishing attempts and malware.
• User behavior visibility: Assess how well IT teams can monitor and analyze user activity.

Example KPI:

• Reduce Mean Time to Respond (MTTR) to security threats by 40% compared to the current security stack.

3. Operational Efficiency and IT Management KPIs

One of the biggest advantages of SASE is reducing operational overhead by consolidating security and networking tools. The PoC should evaluate whether IT teams experience a simplified, centralized management process with less manual effort.

Key Metrics to Track:

• Time required for security policy changes: Measure how long it takes to implement and enforce new security rules.
• Reduction in manual configuration effort: Assess whether automation reduces IT workloads.
• Number of tools replaced/consolidated: Count how many legacy solutions (e.g., VPNs, firewalls) are eliminated.
• Single-pane-of-glass visibility: Evaluate how effectively IT teams can monitor and manage networking and security through a unified dashboard.

Example KPI:

• Decrease time spent on network troubleshooting by at least 50% through centralized monitoring and automation.

4. Cost Savings and ROI KPIs

SASE solutions can drive significant cost savings by replacing expensive MPLS connections, reducing hardware dependencies, and simplifying IT management. The PoC should calculate both direct cost reductions and long-term ROI.

Key Metrics to Track:

• Reduction in MPLS costs: Compare expenses before and after implementing SASE.
• Lower hardware and maintenance costs: Track how much is saved by replacing firewalls, VPN concentrators, and SD-WAN appliances.
• IT staff productivity gains: Measure labor cost reductions due to automation and simplified operations.
• License cost comparisons: Compare existing security and networking license costs with SASE pricing models.

Example KPI:

• Reduce overall networking and security operational costs by 25% over 12 months.

Avoiding Common Pitfalls When Defining Success Criteria

To ensure the PoC produces clear, actionable results, CIOs and CISOs must avoid common pitfalls, including:

1. Setting vague success criteria: Success should be measurable—avoid qualitative goals like “improve security” without defining what improvement means.
2. Focusing only on technical validation: Business value must be a key factor in success measurement.
3. Ignoring real-world testing conditions: The PoC should replicate live network traffic, user behaviors, and attack scenarios.
4. Relying solely on vendor-provided metrics: Independent validation is essential to ensure unbiased decision-making.
5. Failing to define a comparison baseline: Without benchmarking against the current state, it’s difficult to quantify improvements.

Finalizing Success Criteria Before PoC Execution

Once success metrics are defined, CIOs and CISOs should:

• Document all success criteria and KPIs in an evaluation framework.
• Align stakeholders across security, networking, and business teams to agree on priorities.
• Establish a data collection process to measure results throughout the PoC.
• Set thresholds for success—determine what level of improvement justifies moving forward with deployment.

By establishing clear success criteria and measurable KPIs, CIOs and CISOs ensure that their SASE PoC delivers quantifiable business value rather than just technical validation. A structured, data-driven approach helps avoid uncertainty, accelerates decision-making, and ensures a confident transition to full-scale deployment.

With success criteria in place, the next step is to select the right SASE vendors for PoC testing.

Step 3: Select the Right SASE Vendors for PoC Testing

The success of a SASE (Secure Access Service Edge) Proof of Concept (PoC) heavily depends on selecting the right vendors to test. With numerous SASE solutions available in the market, the decision on which vendor to include in the PoC process is crucial. It’s not only about choosing a vendor that meets technical specifications but also one that aligns with your organization’s business, security, and operational needs.

Key Factors in Vendor Selection

When choosing vendors for your PoC, there are several key factors to consider, each of which will contribute to the success of the PoC and the long-term benefits of implementing the SASE solution. Below are the most important considerations for selecting the right SASE vendor.

1. Cloud-Native Architecture

SASE is fundamentally a cloud-native architecture, designed to provide secure access to users, applications, and data regardless of location. As such, it’s critical to evaluate vendors based on their ability to offer a fully cloud-based solution that can seamlessly integrate with cloud platforms, SaaS applications, and hybrid environments.

Why it matters:

• Scalability: A cloud-native architecture ensures that the solution can easily scale to meet future growth, whether it’s expanding the user base, increasing traffic, or adding more remote locations.
• Global Reach: The solution should deliver consistent performance no matter where users are located. Cloud-native solutions typically have distributed points of presence (PoPs) to ensure global reach, reducing latency and providing secure access to applications in any geographic region.
• Seamless Cloud Integration: A cloud-first SASE solution will integrate easily with public clouds like AWS, Azure, and Google Cloud, facilitating a smooth transition to a cloud-first or hybrid IT infrastructure.

What to look for:

• Improved User Experience: Integrating network and security solutions ensures seamless access control and application performance, whether users are on-site, remote, or using cloud applications.
• Reduced Latency and Complexity: With both functions working together, security inspection (like threat filtering, DLP, or CASB) happens alongside traffic optimization (like SD-WAN), improving both performance and security without introducing extra latency.

What to look for:

• A single-vendor solution that provides integrated networking (SD-WAN) and security features (CASB, SWG, ZTNA, Firewall as a Service).
• Converged management interfaces for easier oversight.
• Evidence of how security and networking functions are optimized together to reduce complexity.

3. Scalability and Flexibility

Scalability is a major consideration when selecting SASE vendors, as organizations need a solution that can grow with them. The vendor must be able to handle increased demands as your organization expands, adding more remote users, devices, or cloud-based applications.

Why it matters:

• Adaptability: The solution should scale effortlessly to accommodate changing user numbers, network traffic, and evolving security needs without requiring extensive reconfiguration or downtime.
• Flexibility for Future Needs: As your organization transitions further into the cloud, expands its edge environments, or integrates new technologies, the solution should provide future-proof capabilities.
• Low Maintenance: Scalable and flexible systems are often self-optimizing, requiring fewer resources and manual interventions to manage capacity adjustments.

What to look for:

• Demonstrations of how the solution adapts to increased users or traffic without compromising performance.
• Flexibility to add new sites, users, or workloads on-demand as part of a growing, distributed network.
• Evidence of elastic scaling, such as auto-scaling features for cloud environments.

4. Performance and Reliability

While selecting a vendor for your PoC, ensure that the solution is high-performing and reliable. Security and networking must operate at optimal performance without introducing significant latency or affecting application performance. A SASE solution that suffers from lag or downtime will fail to meet business expectations.

Why it matters:

• Consistent Performance: The solution must provide stable, fast, and reliable access to business-critical applications, whether users are in the office, remote, or accessing cloud-based resources.
• Business Continuity: A failure in the SASE platform could disrupt business operations, leading to productivity losses and reputational damage. Ensuring service availability and uptime is paramount for your PoC.
• Performance under Load: The solution should maintain performance levels even as network demand fluctuates, especially in high-traffic periods or during an increase in remote access.

What to look for:

• Latency benchmarks that demonstrate low response times and minimal delays.
• Evidence of load balancing to handle variable traffic loads across distributed locations.
• Service Level Agreements (SLAs) that guarantee uptime and provide clear recourse for failures.

5. Vendor Reputation and Support

A vendor’s reputation and their support offerings play a crucial role in a successful PoC. Ideally, the chosen vendor should offer solid customer support, a proven track record, and industry recognition. A reliable vendor also ensures that there’s ample technical expertise to assist throughout the PoC, ensuring that problems are resolved promptly and efficiently.

Why it matters:

• Ongoing Support: Vendors should offer 24/7 support, including troubleshooting, guidance, and proactive monitoring to ensure that the solution functions optimally during the PoC.
• Customer Feedback: Reviews and case studies from other organizations provide insight into the vendor’s capabilities and the effectiveness of their SASE solutions in real-world settings.

What to look for:

• Customer success stories and testimonials showcasing the vendor’s ability to deliver results.
• Support options such as technical assistance during setup, troubleshooting, and performance testing.
• Response times and SLAs for resolving issues during the PoC.

Avoiding Common Pitfalls in Vendor Selection

While selecting SASE vendors, it’s essential to avoid several common pitfalls that can hinder the success of the PoC:

1. Testing too many solutions at once: Overloading the PoC with too many vendors can dilute focus, confuse decision-making, and create a disjointed evaluation process. Stick to a manageable number of vendors that meet your criteria.
2. Focusing only on cost: While pricing is a key consideration, it should not be the only factor driving your decision. Prioritize business value, security effectiveness, and scalability over short-term cost savings.
3. Ignoring future growth: Select a vendor that can scale with your business over time. Avoid vendors whose solutions are too rigid or limited in their ability to adapt to future requirements.
4. Overlooking integration complexity: Ensure that the vendor’s solution easily integrates with your existing IT infrastructure, including legacy systems, cloud platforms, and third-party tools.

Selecting the right SASE vendor is crucial for the success of the PoC. By focusing on key factors such as cloud-native architecture, convergence of security and networking, scalability, performance, and vendor reputation, CIOs and CISOs can ensure that the PoC delivers meaningful insights into the feasibility and potential value of the solution.

With the right vendor in place, the next step is to design a realistic and controlled PoC environment.

Step 4: Design a Realistic and Controlled PoC Environment

Once the right SASE vendor has been selected, the next critical step in a successful PoC is to design a realistic and controlled testing environment. This phase is vital because a PoC that doesn’t accurately reflect your production environment can lead to skewed results, causing you to make ill-informed decisions.

To ensure the PoC accurately measures how the SASE solution will perform under real-world conditions, it’s essential to create a test environment that closely mirrors the complexities and challenges your organization faces.

Why the PoC Environment Matters

The design of the PoC environment directly impacts the validity and accuracy of test results. A PoC environment that is too simplified or doesn’t take into account key variables such as user behavior, network traffic, and security threats may fail to highlight potential issues with the solution.

Conversely, an environment that is too complex could introduce variables that make it difficult to isolate the impact of the SASE solution itself. Striking the right balance is crucial for gathering reliable data that will inform your decision-making process.

The goal is to design an environment where the real-world network traffic and security threats can be accurately simulated so that CIOs and CISOs can observe the actual effectiveness of the solution in action.

Key Elements to Consider When Designing the PoC Environment

1. Realistic Network Traffic Simulation

The first aspect to consider when designing the PoC environment is how to replicate the real network traffic your organization experiences daily. The effectiveness of a SASE solution is dependent on its ability to handle various types of network traffic, including cloud applications, SaaS services, internet traffic, and remote access needs.

Why it matters:

• Accurate Testing: If the test environment uses artificially simple traffic patterns or lacks real-world variability (e.g., differing bandwidth demands, latency conditions), the results may not accurately reflect the performance of the SASE solution under normal operational conditions.
• Performance Validation: A well-designed test environment allows for the accurate measurement of latency, throughput, and traffic optimization features of the SASE solution.

What to do:

• Replicate traffic patterns that mimic typical usage, such as traffic from branch offices, remote employees, and cloud-based applications.
• Consider traffic prioritization based on business needs (e.g., prioritizing voice, video, and business-critical applications).
• Simulate peak traffic loads to measure the scalability and resilience of the solution under high-stress conditions.

2. Hybrid Workforce and Multi-Cloud Environments

Today, most organizations operate in a hybrid work model, with employees working from various locations—offices, remote environments, or on-the-go—and utilizing multi-cloud infrastructure. It’s critical that your PoC environment reflects this complexity.

Why it matters:

• User Location Flexibility: The SASE solution needs to provide secure access to applications regardless of whether employees are working on-site, remotely, or in distributed locations across the globe.
• Cloud Integration: A PoC should test the solution’s ability to seamlessly integrate with public and private clouds as well as SaaS applications (e.g., Microsoft 365, Salesforce).
• Access Control Across Multiple Locations: You need to assess how the solution handles secure access to resources from various locations and whether it can enforce consistent Zero Trust security policies, regardless of user location.

What to do:

• Test the SASE solution’s ability to provide secure access across different work environments, including remote offices, mobile devices, and on-premises locations.
• Ensure that the PoC environment includes multi-cloud infrastructure, testing the solution’s ability to handle traffic and security between different cloud services, including the integration of SaaS, PaaS, and IaaS services.
• Simulate user authentication and access controls across these environments to evaluate the enforcement of Zero Trust and least-privilege access policies.

3. Security Threat Simulation

A core component of a SASE solution is its ability to provide comprehensive security measures, including protection against cyber threats like malware, ransomware, phishing, and data breaches. The PoC environment should not only focus on performance but also simulate realistic security attack scenarios to test the solution’s effectiveness.

Why it matters:

• Threat Detection and Prevention: To assess how well the SASE solution can detect and block threats, you must simulate real-world attacks, such as ransomware, advanced persistent threats (APTs), and DDoS attacks.
• Realistic Security Policies: It’s important to test security policies and configurations under conditions that mimic the actual threats your organization faces, as opposed to using simple, pre-configured tests.

What to do:

• Simulate cyber-attacks such as malware infections, phishing attempts, or insider threats to evaluate the effectiveness of the SASE solution’s security features (e.g., Next-Gen Firewall, Intrusion Prevention Systems, Data Loss Prevention).
• Test the solution’s anomaly detection, real-time threat intelligence integration, and policy enforcement against simulated attack vectors.
• Assess how quickly the system detects and responds to these security events to measure MTTD (Mean Time to Detect) and MTTR (Mean Time to Respond).

4. Integration with Existing IT Infrastructure

A critical factor in designing a PoC environment is ensuring that the SASE solution integrates smoothly with your organization’s existing network infrastructure and security tools. A major selling point of SASE is its ability to replace legacy tools (e.g., traditional firewalls, VPNs, MPLS), but it must also coexist with any systems that are not yet migrated to the cloud.

Why it matters:

• Minimal Disruption: The PoC environment should test how the SASE solution integrates with your existing infrastructure, ensuring minimal disruption during migration.
• Legacy System Compatibility: As many organizations still rely on legacy tools, it’s essential to test whether the SASE solution can coexist and integrate with older systems that will be replaced or phased out over time.
• Seamless Transition: A PoC that accounts for legacy systems will help ensure that the final deployment does not create security or operational gaps.

What to do:

• Test how the SASE solution integrates with existing firewalls, SD-WAN infrastructure, VPN solutions, and endpoint security tools.
• Verify how existing policies (such as user access controls or VPN configurations) migrate into the SASE solution and whether they require any changes.
• Ensure compatibility with legacy applications that may not be fully cloud-native and check if performance is maintained during the transition period.

5. Test Automation and Data Collection

One of the best practices for designing a controlled PoC environment is the use of test automation and data collection tools. This enables a more objective evaluation of the solution, reduces manual errors, and provides valuable insights into its performance over time.

Why it matters:

• Consistent and Repeatable Testing: Automation helps ensure tests are conducted consistently across different environments and time periods, producing more reliable results.
• Deeper Insights: Automated testing allows for continuous monitoring of key metrics, providing a wealth of data that can be analyzed to draw conclusions about the solution’s effectiveness.

What to do:

• Set up automated testing tools to simulate traffic, measure performance, and record security incident response times.
• Use data analytics platforms to analyze results and identify patterns or areas for improvement.
• Ensure that data collection is comprehensive, covering all aspects of performance, security, and user experience.

Designing a realistic and controlled PoC environment is essential for testing a SASE solution under conditions that closely mirror your organization’s actual network and security requirements. By accurately simulating network traffic, security threats, and integration with existing infrastructure, CIOs and CISOs can ensure that the results of the PoC are valid and actionable.

With the PoC environment set up, the next step is to execute the PoC with cross-functional teams.

Step 5: Execute the PoC with Cross-Functional Teams

Once the PoC environment is designed and set up, the next crucial step is to execute the PoC with cross-functional teams. This step involves putting the solution to the test across various areas of your organization to ensure that it meets the needs of not just the IT and security teams, but also business stakeholders.

A successful PoC should go beyond just testing the technology—it should provide insights into how the solution can drive business value, improve security posture, and enhance operational efficiency.

This process involves collaborating across departments, involving not only technical teams but also business decision-makers, to gain a holistic perspective on the solution’s potential impact. The goal is to ensure that the PoC is comprehensive, addressing both technical and business objectives.

Why Cross-Functional Collaboration is Crucial

Cross-functional collaboration is essential because SASE (Secure Access Service Edge) solutions impact multiple aspects of an organization’s operations, from IT and security teams to remote employees, branch offices, and executive leadership. The solution should provide value not only from a security perspective but also from a performance, usability, and business outcomes viewpoint.

Why it matters:

• Holistic Evaluation: A PoC that only includes IT or security teams might miss out on crucial business considerations such as user experience, cost savings, or operational efficiency. Involving cross-functional teams ensures a comprehensive evaluation of the solution from all angles.
• Informed Decision-Making: By bringing in different departments, decision-makers can better assess whether the solution aligns with business needs and strategic goals.
• Faster Adoption: The involvement of cross-functional teams, especially business leaders and end-users, can lead to smoother adoption of the solution after PoC success since those teams are already familiar with its benefits.

Involving the Right Stakeholders

A PoC should involve a variety of stakeholders who can evaluate different aspects of the SASE solution’s performance. Here’s a breakdown of the key teams and stakeholders that should participate in the PoC:

1. IT and Security Teams

The core technical teams are essential for testing the security features, network performance, and integration capabilities of the SASE solution. These teams will test how well the solution integrates with existing infrastructure, ensures secure access to cloud resources, reduces risk, and handles various network traffic scenarios.

• Assess the solution’s ability to support business continuity and remote workforce flexibility, key factors in today’s digital-first environments.

3. End-Users and Remote Employees

Including end-users in the PoC process is critical, as the ultimate goal of SASE is to provide users with secure, seamless access to applications and resources, no matter their location. For remote employees, especially, it’s crucial to assess the user experience under real-world conditions.

Why they matter:

• Real-World Usability: End-users will directly interact with the solution, so understanding their experience is key to evaluating user-friendliness, performance, and accessibility.
• Feedback on Adoption: How quickly do users adapt to the new system? Are there noticeable improvements in network performance, latency, or application access speeds?

What to do:

• Survey end-users about their experience with the SASE solution, including how quickly they can access applications and whether there are any latency issues or challenges with authentication.
• Test remote workers’ ability to seamlessly access cloud applications while maintaining a secure environment, ensuring that the SASE solution supports Zero Trust policies and consistent security enforcement.
• Gather feedback on how the solution impacts productivity—for example, do users experience fewer network interruptions or faster access to SaaS applications?

4. Vendor Support and Account Management

Another important aspect of the PoC is the involvement of the vendor’s support team and account managers. These individuals can provide vital assistance, guidance, and insight throughout the PoC process, helping to resolve technical issues quickly and ensuring that the solution is being tested to its fullest potential.

Why they matter:

• Vendor Expertise: The vendor’s team can help troubleshoot issues, optimize configurations, and provide best practices to ensure the PoC tests the solution’s capabilities thoroughly.
