At a time when digital transformation is reshaping industries worldwide, securing networks has become a top priority for organizations across all sectors. One of the most promising developments in network security is the Secure Access Service Edge (SASE) model, a framework that integrates networking and security functions into a unified, cloud-delivered service.
This model offers a holistic approach to protecting modern enterprises as they navigate the complexities of digital operations, cloud adoption, and remote workforces. For industrial organizations such as manufacturing, energy, and utilities, the relevance of SASE cannot be overstated. As these organizations increasingly depend on interconnected systems and cloud-based applications, they face unique challenges and vulnerabilities that SASE is well-positioned to address.
Overview of SASE
Secure Access Service Edge, or SASE (pronounced “sassy”), is a network architecture that merges wide-area networking (WAN) and network security services like secure web gateways (SWG), cloud access security brokers (CASB), firewall as a service (FWaaS), and zero-trust network access (ZTNA) into a single, integrated cloud-native service model.
Developed by Gartner in 2019, SASE aims to simplify network management and enhance security by providing a unified approach that extends security and connectivity to all users and devices, regardless of their location. By consolidating these functions into a cloud-based service, SASE enables organizations to reduce complexity, improve security posture, and support the growing demand for cloud-based applications and remote work environments.
In traditional network models, security functions are often deployed at a central data center, which can lead to inefficiencies and delays as traffic is routed through the center for inspection and policy enforcement. SASE, however, allows security policies to be enforced at the edge of the network, closer to the user or device, which enhances performance and reduces latency. This distributed approach is particularly beneficial for organizations with geographically dispersed operations and a significant number of remote users, as it provides consistent security coverage without the need for complex network configurations or costly hardware investments.
Importance of SASE in Industrial Settings
Industrial organizations, including those in manufacturing, energy, and utilities, are undergoing a significant transformation as they embrace digital technologies to enhance operational efficiency, reduce costs, and drive innovation. The adoption of industrial Internet of Things (IoT) devices, cloud-based applications, and remote monitoring systems has introduced new levels of connectivity and data exchange, enabling real-time insights and smarter decision-making. However, this digital shift has also expanded the attack surface, exposing industrial networks to a wider range of cyber threats.
Traditionally, industrial networks were isolated from the internet and external networks, which provided a natural layer of security known as air-gapping. However, as the need for remote access, cloud integration, and interconnected systems grows, air-gapping has become impractical. Modern industrial networks are increasingly connected, integrating information technology (IT) and operational technology (OT) environments to enable seamless data flow and optimized operations. This convergence of IT and OT, while beneficial, also introduces significant security challenges, as it often involves the integration of legacy systems with new technologies, creating vulnerabilities that cybercriminals can exploit.
This is where SASE comes into play. The SASE model offers a comprehensive security framework that is well-suited to the unique needs of industrial organizations. By providing secure access to cloud applications and remote resources, SASE ensures that only authorized users and devices can access sensitive data and systems. Its zero-trust security model, which assumes that no user or device should be trusted by default, further strengthens defenses against cyber threats by requiring continuous verification and monitoring of all network activities.
For industrial organizations, adopting SASE means more than just enhancing security; it also supports operational resilience and business continuity. With SASE, organizations can ensure that their networks are not only protected from external threats but also capable of maintaining performance and reliability under various conditions. For instance, in the event of a cyberattack or system failure, SASE’s distributed architecture enables rapid response and recovery, minimizing downtime and mitigating the impact on critical operations.
Moreover, SASE helps industrial organizations address regulatory compliance and data privacy requirements, which are increasingly stringent in sectors like energy and utilities. By centralizing security policies and providing visibility into all network activities, SASE allows organizations to demonstrate compliance with industry standards and regulations more effectively. This is particularly important for organizations that must adhere to frameworks like the North American Electric Reliability Corporation Critical Infrastructure Protection (NERC CIP) or the General Data Protection Regulation (GDPR), which mandate strict controls over access to critical systems and data.
As industrial organizations navigate the complexities of digital transformation, the adoption of SASE is becoming an essential component of their cybersecurity strategy. However, despite its benefits, implementing SASE is not without challenges. Several roadblocks can hinder the successful deployment of SASE in industrial settings, including the need to integrate legacy systems, converge operational technology with information technology, develop a robust cybersecurity culture, and comply with regulatory requirements.
In the following sections, we will explore these roadblocks in detail and provide insights into how industrial organizations can overcome them to achieve a secure and resilient network environment.
Roadblock 1: Legacy Systems and Infrastructure
Legacy systems in industrial environments refer to older computer systems, software, or hardware that are still in use despite being outdated. These systems, which include Supervisory Control and Data Acquisition (SCADA) and Industrial Control Systems (ICS), are critical components in the operation of industrial processes. SCADA systems, for instance, are used to monitor and control industrial operations remotely, while ICS manages and automates the machinery and processes within an industrial setting.
The typical characteristics of legacy systems in industrial environments include their reliance on outdated hardware and software, proprietary protocols, and a lack of support for modern cybersecurity measures. Many of these systems were designed and implemented decades ago, long before the advent of the internet and the current threat landscape. As a result, they often lack the ability to integrate seamlessly with modern IT systems or support advanced security protocols, making them vulnerable to cyberattacks and posing significant challenges for organizations seeking to implement new technologies like SASE.
Integration Challenges
Integrating SASE with legacy systems is a formidable challenge for industrial organizations. The core difficulty lies in the incompatibility between the outdated architecture of legacy systems and the modern, cloud-based nature of SASE. Legacy systems were typically designed to operate in isolated environments with limited external connectivity, relying on proprietary communication protocols that are not compatible with standard internet protocols used in SASE solutions.
This lack of compatibility means that industrial organizations must invest significant resources in developing custom integration solutions to bridge the gap between legacy systems and SASE. This often involves upgrading or retrofitting legacy systems with new interfaces and middleware that can translate between old and new protocols. Additionally, the security mechanisms of legacy systems are typically not robust enough to meet the stringent security requirements of SASE, necessitating further modifications and enhancements to ensure adequate protection.
The challenge is compounded by the fact that many legacy systems are mission-critical, meaning any disruption during the integration process can have severe consequences for the organization’s operations. For example, in a manufacturing plant, an outage caused by a failed integration could halt production, leading to significant financial losses and potentially damaging the company’s reputation. As a result, industrial organizations must carefully plan and execute integration projects to minimize risks and ensure a smooth transition to SASE.
Resource Constraints
Resource constraints are another significant roadblock to integrating legacy systems with SASE. Upgrading or replacing legacy systems requires substantial financial investment, which many industrial organizations are reluctant or unable to make. The costs associated with hardware upgrades, software development, and the hiring of specialized personnel can be prohibitive, especially for organizations operating on tight budgets.
Personnel constraints also play a role, as many industrial organizations lack the in-house expertise needed to manage the integration of legacy systems with modern security frameworks. The skills required to work with legacy systems are becoming increasingly rare, as experienced professionals retire and fewer young engineers are trained in these older technologies. This shortage of skilled personnel can delay integration projects and increase the likelihood of errors, further complicating the implementation of SASE.
Additionally, the need to minimize downtime during the integration process poses a significant challenge. Industrial organizations operate in highly competitive markets where even a short period of downtime can result in substantial financial losses. As a result, organizations must carefully balance the need to upgrade their legacy systems with the imperative to maintain continuous operations, often leading to compromises that delay or limit the effectiveness of SASE implementation.
Sample Scenario
Consider a manufacturing company, “Industrial Manufacturing Co.,” that operates several plants using legacy SCADA systems to monitor and control its production processes. These SCADA systems were installed over two decades ago and are based on proprietary protocols that do not support modern security measures. Recognizing the need to enhance its cybersecurity posture and protect its operations from cyber threats, the company decides to implement a SASE solution to secure its network and enable remote access for its employees.
However, the integration process quickly reveals several challenges. The legacy SCADA systems cannot communicate directly with the cloud-based SASE solution, requiring the development of custom interfaces and middleware to bridge the gap. The company also discovers that the SCADA systems’ security mechanisms are inadequate, necessitating significant modifications to ensure compatibility with the SASE solution’s security protocols.
As the integration project progresses, the company faces additional resource constraints. The budget allocated for the project is quickly exhausted, and the company struggles to find engineers with the necessary expertise to work with both legacy SCADA systems and modern SASE solutions. To minimize downtime, the company must carefully plan the integration to avoid disrupting its production processes, further complicating the project and delaying the implementation of SASE.
Despite these challenges, “Industrial Manufacturing Co.” eventually completes the integration, but not without significant delays and cost overruns. The experience highlights the difficulties of integrating legacy systems with modern security frameworks and underscores the need for careful planning and resource allocation when implementing SASE in industrial environments.
Roadblock 2: Operational Technology (OT) and Information Technology (IT) Convergence
Operational Technology (OT) and Information Technology (IT) serve distinct purposes within industrial settings. OT encompasses systems that control and monitor physical processes, such as machinery, equipment, and production lines in a manufacturing plant. These systems are responsible for real-time operations and require high reliability, availability, and safety to ensure the smooth functioning of industrial processes.
In contrast, IT involves systems that manage data processing, business operations, and communication within an organization. IT systems are typically more dynamic, focusing on data management, cybersecurity, and user support. The primary goal of IT is to facilitate information flow and support business functions, such as financial management, human resources, and customer relationship management.
While OT systems prioritize stability and safety, IT systems emphasize flexibility and security. This fundamental difference creates challenges when attempting to integrate OT and IT under a unified SASE model, as each domain has distinct requirements, protocols, and operational priorities.
Challenges of Convergence
The convergence of OT and IT networks is a complex undertaking that introduces several security and operational challenges. One of the primary challenges is the need to integrate two fundamentally different types of systems with distinct architectures, protocols, and security requirements. OT systems often use proprietary protocols and were designed with limited connectivity to external networks, making them less adaptable to integration with IT systems that rely on standard internet protocols.
Another challenge is the potential security risks associated with converging OT and IT networks. OT systems were traditionally isolated from the internet and external networks, providing a natural layer of security. However, as organizations increasingly connect OT systems to IT networks to enable remote monitoring, data analysis, and process optimization, they expose OT systems to the same cyber threats that target IT networks.
This increased exposure requires industrial organizations to adopt new security measures and protocols to protect both OT and IT systems. However, many existing security solutions are designed for IT environments and may not be compatible with the unique requirements of OT systems. As a result, organizations must invest in developing customized security solutions that can provide comprehensive protection across both domains.
Risk of Downtime and Production Impact
The integration of OT and IT networks also introduces the risk of downtime and production impact. OT systems are responsible for controlling critical industrial processes, and any disruption to these systems can have severe consequences for an organization’s operations. For example, a network outage or cyberattack that affects an OT system in a manufacturing plant could halt production, leading to significant financial losses, damaged equipment, and potential safety hazards for workers.
To minimize these risks, industrial organizations must carefully plan the integration of OT and IT networks and implement robust security measures to protect against potential threats. This often involves adopting a phased approach to integration, allowing organizations to test and validate each stage of the process before moving on to the next. Additionally, organizations must ensure that their IT and OT teams work closely together to develop comprehensive security protocols and contingency plans that can quickly respond to any incidents.
Security Implications
The convergence of OT and IT networks introduces several security implications that must be addressed to ensure the successful implementation of SASE. One of the primary concerns is the increased attack surface that results from connecting previously isolated OT systems to IT networks. This expanded attack surface makes it easier for cybercriminals to gain access to critical industrial systems and disrupt operations.
To mitigate these risks, industrial organizations must adopt a zero-trust security model, which assumes that no user or device should be trusted by default and requires continuous verification and monitoring of all network activities. This approach helps to identify and mitigate potential threats before they can cause significant damage to the organization’s operations.
Additionally, organizations must invest in developing specialized security protocols that can address the unique requirements of both OT and IT systems. This may involve implementing advanced threat detection and response capabilities, segmentation of OT and IT networks to limit the spread of potential threats, and regular security assessments to identify and address vulnerabilities.
Sample Scenario
Imagine a utility company, “Energy Solutions Inc.,” that operates a network of power plants and distribution centers using OT systems to control and monitor its operations. The company decides to implement a SASE solution to enhance its network security and enable remote access for its employees. However, the integration of OT and IT networks presents several challenges.
The company’s OT systems use proprietary protocols and were designed to operate in isolation from external networks. Integrating these systems with the IT network and the SASE solution requires significant modifications and the development of custom interfaces to ensure compatibility. Additionally, the company must address the security implications of connecting its OT systems to the internet, as this exposes them to potential cyber threats.
As the integration project progresses, “Energy Solutions Inc.” encounters several security challenges. The increased attack surface resulting from the convergence of OT and IT networks makes it easier for cybercriminals to target the company’s critical systems. To mitigate these risks, the company adopts a zero-trust security model and implements advanced threat detection and response capabilities. However, the complexity of the integration and the need to develop specialized security protocols delays the implementation of SASE and increases the project’s cost.
Despite these challenges, “Energy Solutions Inc.” successfully integrates its OT and IT networks under the SASE model, enhancing its security posture and enabling remote access for its employees. The experience highlights the importance of addressing the unique challenges and security implications of OT and IT convergence when implementing SASE in industrial environments.
Roadblock 3: Cybersecurity Culture and Skills Gap
Importance of Cybersecurity Awareness in Industrial Settings
In industrial settings, a robust cybersecurity culture is crucial to safeguarding critical infrastructure and ensuring the safe and reliable operation of industrial processes. Unlike traditional IT environments, where the primary focus is on protecting data and systems, industrial settings must also consider the physical safety of personnel and equipment. Cyberattacks on industrial systems can have severe consequences, including equipment damage, production downtime, environmental harm, and even threats to human life.
To build a strong cybersecurity culture, organizations must foster awareness among employees at all levels about the importance of cybersecurity and the potential risks associated with cyber threats. This involves educating employees about common attack vectors, such as phishing and malware, as well as the specific threats that target industrial systems, such as ransomware and insider attacks. By promoting a culture of vigilance and accountability, organizations can reduce the likelihood of successful cyberattacks and minimize the impact of security incidents.
Skill Deficiencies
One of the most significant challenges facing industrial organizations in the implementation of SASE is the shortage of cybersecurity professionals with expertise in both IT and OT systems. The convergence of IT and OT networks requires a unique skill set that combines knowledge of traditional IT security practices with an understanding of the specific requirements and vulnerabilities of OT systems.
This skills gap is further exacerbated by the rapid pace of technological change in the cybersecurity landscape, which requires ongoing training and development to keep up with new threats and security solutions. Many industrial organizations struggle to find qualified personnel with the necessary expertise to manage the integration of SASE and ensure the security of their networks.
The shortage of skilled cybersecurity professionals can lead to delays in the implementation of SASE, as organizations are forced to rely on external consultants or allocate additional resources to training existing staff. This can increase the overall cost of the project and reduce the effectiveness of the SASE solution, as inexperienced personnel may make mistakes or overlook critical security vulnerabilities.
Training and Change Management
To address the skills gap and ensure the successful implementation of SASE, industrial organizations must invest in comprehensive training programs and change management strategies. Training programs should be tailored to the specific needs of the organization and cover a range of topics, including IT and OT security practices, SASE architecture and implementation, and incident response procedures.
In addition to technical training, organizations should also focus on developing soft skills, such as communication and collaboration, to ensure that IT and OT teams can work together effectively. This is particularly important in the context of SASE implementation, as the convergence of IT and OT networks requires close cooperation and coordination between teams.
Change management strategies should be designed to address the resistance to new technologies and methodologies that is common in traditional industrial settings. This involves engaging stakeholders at all levels of the organization, from senior management to frontline employees, to ensure that they understand the benefits of SASE and are committed to its successful implementation.
By investing in training and change management, organizations can build the skills and knowledge needed to implement SASE effectively and create a culture of continuous improvement that supports the ongoing development of cybersecurity capabilities.
Resistance to Change
Resistance to change is a common challenge in traditional industrial settings, where employees may be accustomed to established processes and hesitant to adopt new technologies or methodologies. This resistance can be particularly pronounced when it comes to cybersecurity, as many employees may not fully understand the importance of protecting industrial systems from cyber threats or may perceive cybersecurity measures as unnecessary or disruptive.
To overcome resistance to change, industrial organizations must engage employees at all levels and demonstrate the value of SASE in protecting the organization’s operations and ensuring its long-term success. This involves communicating the benefits of SASE in clear, concise terms and providing examples of how the solution can enhance security, improve efficiency, and support business objectives.
Organizations should also provide opportunities for employees to participate in the implementation process and contribute to the development of security policies and procedures. By involving employees in the decision-making process and giving them a sense of ownership over the outcome, organizations can reduce resistance to change and foster a culture of collaboration and continuous improvement.
Sample Scenario
Consider a chemical manufacturing company, “ChemTech Industries,” that decides to implement a SASE solution to enhance its cybersecurity posture and protect its critical infrastructure. The company operates several facilities that use OT systems to control and monitor its production processes, as well as IT systems for business operations and data management.
As the company begins the implementation process, it quickly encounters several challenges related to its cybersecurity culture and skills gap. Many employees, particularly those in the OT environment, are resistant to the new technology and skeptical of the need for enhanced cybersecurity measures. They view the SASE implementation as a disruption to their established processes and are reluctant to adopt new practices or technologies.
Additionally, the company lacks in-house expertise in both IT and OT cybersecurity, making it difficult to manage the integration of SASE and ensure the security of its networks. To address these challenges, “ChemTech Industries” invests in a comprehensive training program that covers both IT and OT security practices, as well as the specific requirements of the SASE solution.
The company also implements a change management strategy that involves engaging stakeholders at all levels and demonstrating the benefits of SASE in protecting the organization’s operations. By fostering a culture of collaboration and continuous improvement, “ChemTech Industries” is able to overcome resistance to change and successfully implement the SASE solution, enhancing its security posture and protecting its critical infrastructure.
Roadblock 4: Regulatory Compliance and Data Privacy
Regulatory Landscape for Industrial Organizations
Industrial organizations operate in highly regulated environments, where compliance with various regulations and standards is essential to ensure the safety, security, and reliability of operations. These regulations can vary significantly depending on the industry and geographic location, but they often include requirements for data protection, cybersecurity, and operational resilience.
For example, in the energy sector, organizations must comply with the North American Electric Reliability Corporation Critical Infrastructure Protection (NERC CIP) standards, which mandate strict controls over access to critical systems and data to protect the reliability of the electric grid. Similarly, organizations that process personal data must comply with data protection regulations such as the General Data Protection Regulation (GDPR) in Europe or the California Consumer Privacy Act (CCPA) in the United States, which impose stringent requirements for data privacy and security.
These regulations often have significant implications for the implementation of SASE, as organizations must ensure that their network security solutions comply with all relevant requirements and do not introduce new risks or vulnerabilities.
Compliance Challenges with SASE
Ensuring compliance with regulatory requirements when adopting a SASE framework can be a complex and challenging process. One of the primary challenges is the need to ensure that data flows across borders and cloud environments comply with data protection regulations. For example, under GDPR, organizations must ensure that personal data is not transferred outside the European Economic Area (EEA) unless specific conditions are met, such as the implementation of adequate safeguards or obtaining explicit consent from the data subjects.
This requirement can be difficult to meet in the context of SASE, as the cloud-based nature of the solution often involves the transfer of data across multiple geographic locations. To ensure compliance, organizations must carefully select SASE providers that offer data residency options and ensure that all data flows are properly documented and controlled.
Another compliance challenge is the need to demonstrate that all security measures meet the requirements of relevant regulations and standards. This often involves conducting regular security assessments and audits to ensure that the SASE solution is configured correctly and provides the necessary level of protection. Additionally, organizations must ensure that their SASE solution includes robust logging and monitoring capabilities to provide visibility into all network activities and support regulatory reporting requirements.
Data Privacy Concerns
Data privacy is a significant concern in industrial contexts, where operational data can be critical to national security or competitive advantage. Industrial organizations must ensure that their SASE solution provides robust data protection measures to prevent unauthorized access to sensitive information and protect against data breaches.
This often involves implementing advanced encryption and access control mechanisms to protect data in transit and at rest, as well as ensuring that all data flows are properly segmented and monitored to prevent unauthorized access. Additionally, organizations must ensure that their SASE solution includes robust incident response capabilities to quickly detect and respond to potential data breaches.
To address these concerns, industrial organizations must carefully evaluate the data privacy features of their SASE solution and ensure that they meet all relevant regulatory requirements and industry standards. This often involves working closely with legal and compliance teams to develop comprehensive data protection policies and procedures that address the unique requirements of the organization.
Risk Management
Balancing the benefits of SASE with the need to mitigate compliance risks requires a careful approach to risk management. Organizations must conduct a thorough risk assessment to identify potential compliance risks associated with the implementation of SASE and develop strategies to mitigate these risks.
This often involves developing a comprehensive compliance strategy that includes regular security assessments, audits, and monitoring to ensure that all security measures meet the requirements of relevant regulations and standards. Additionally, organizations must ensure that their SASE solution includes robust incident response capabilities to quickly detect and respond to potential security incidents.
By adopting a risk-based approach to compliance, organizations can ensure that their SASE solution provides the necessary level of protection while minimizing the risk of non-compliance and potential regulatory penalties.
Sample Scenario
Imagine a water utility company, “AquaPure Utilities,” that decides to implement a SASE solution to enhance its cybersecurity posture and protect its critical infrastructure. The company operates several water treatment plants and distribution centers that use Operational Technology (OT) systems to control and monitor its operations, as well as Information Technology (IT) systems for business operations and data management.
As AquaPure Utilities begins the SASE implementation process, it encounters several regulatory hurdles related to data privacy and compliance.
