How to Plan a SASE Project: A Detailed 7-Step Guide

As organizations embrace digital transformation, the need to modernize both network and security infrastructures has become increasingly pressing. With remote work on the rise, the proliferation of cloud services, and an expanding network perimeter, traditional approaches to securing and managing enterprise networks are no longer sufficient. This is where Secure Access Service Edge (SASE) comes into play—a framework designed to provide secure, efficient, and flexible network access for today’s dynamic enterprise environments.

Why SASE?

SASE, or Secure Access Service Edge, represents an innovative approach to network security and performance in the era of digital transformation. Introduced by Gartner in 2019, SASE combines wide-area networking (WAN) capabilities with a range of security services, including firewall-as-a-service (FWaaS), secure web gateways (SWG), cloud access security brokers (CASB), and zero-trust network access (ZTNA), into a unified, cloud-native solution.

The primary aim of SASE is to securely connect users, devices, and applications, regardless of their location. This is essential in today’s work environment, where employees are increasingly working remotely and accessing cloud-based applications from various devices. Traditional network security approaches, which often rely on centralized, on-premises security tools, are proving inadequate in addressing the needs of a dispersed workforce. The decentralization of both data and users has made it difficult to maintain security at the edges of the network, and this is where SASE excels.

One of the key benefits of SASE is its ability to simplify network management while enhancing security. By integrating networking and security functions into a single, cloud-delivered platform, organizations can eliminate the need for multiple, disparate systems, reducing complexity and streamlining operations. Additionally, SASE supports edge computing and optimizes the performance of cloud applications by bringing security controls closer to the user or device, wherever they may be located. This enables organizations to apply consistent security policies across all users and devices, regardless of location, leading to improved security posture and greater agility.

Furthermore, SASE allows businesses to adapt to the evolving threat landscape. As cyberattacks grow more sophisticated, traditional perimeter-based defenses struggle to keep up with new vulnerabilities that arise in hybrid environments. SASE offers a more flexible, scalable solution that is better equipped to deal with these modern threats by adopting a zero-trust approach to security, ensuring that no user or device is trusted by default, and all access requests are continuously verified.

SASE is also critical for organizations looking to reduce costs while improving operational efficiency. By consolidating network and security services, SASE reduces the need for multiple vendors and point solutions, resulting in lower hardware, maintenance, and management costs. This makes it an attractive option for businesses that want to modernize their infrastructure without overextending their budget.

In short, SASE is designed to meet the demands of the modern enterprise—enhancing security, simplifying operations, and delivering a superior user experience in an increasingly decentralized and cloud-driven world.

Challenges in Network Modernization

While SASE offers a clear path forward for organizations looking to modernize their network infrastructure, getting there isn’t without its challenges. Adopting a new architecture like SASE requires a thoughtful and strategic approach, as well as the ability to navigate a range of obstacles along the way.

One of the biggest challenges enterprises face when modernizing their network infrastructure is the complexity of their existing systems. Many organizations have built their networks over time, adding new technologies, vendors, and solutions as needed, which often results in a patchwork of systems that don’t easily communicate with each other. Legacy infrastructure can be difficult to integrate with modern cloud-native solutions like SASE, making it challenging to establish a smooth transition.

Another critical challenge is the growing demand for cloud-based services. As organizations shift their workloads and applications to the cloud, maintaining secure and reliable access to these resources becomes increasingly difficult. Traditional security architectures, which are typically built around the idea of a centralized data center, are not equipped to handle the high volume of traffic that needs to be securely routed to cloud services. This often leads to bottlenecks and degraded performance, frustrating users and impeding productivity.

Remote work has also complicated network modernization efforts. With more employees accessing corporate networks from outside the traditional office, the attack surface has expanded dramatically. This poses significant security risks, as organizations must now ensure that remote access is not only fast and reliable but also secure. Legacy virtual private networks (VPNs) are often cumbersome and resource-intensive, leading organizations to search for more scalable solutions—like SASE—that can better accommodate a distributed workforce.

Cost is another factor that can make network modernization a daunting task. While SASE promises long-term cost savings by consolidating network and security services, the initial investment can be substantial. Organizations must weigh the cost of upgrading their infrastructure against the potential benefits of enhanced security and operational efficiency. Additionally, they need to account for the cost of change management and the resources required to retrain staff on the new systems and processes.

In addition, achieving consensus across different teams within the organization can be a significant hurdle. Network and security teams often have different priorities and requirements, and aligning these can be difficult. Implementing SASE requires cross-functional collaboration and buy-in from both IT and business leadership to ensure that the solution meets the needs of the entire organization.

Next Steps: Planning Your SASE Journey

With these challenges in mind, organizations can begin their SASE journey by following a structured approach. In the next section, we’ll discuss the seven essential steps to successfully plan and execute a SASE project, covering everything from building the right team to running a proof of concept.
