To help address these challenges, we invited Warwick Ashford, Senior Analyst, Cybersecurity and Identity at KuppingerCole to share insights from his recently published Leadership Compass report, which analyzes SRA solutions for the industrial world—systems where human and machine access converge, and where risk and complexity are no longer theoretical.

He made the case right away: SRA should not be treated as an add-on, but rather as a core component of modern operational strategy in industrial environments. 

Six Key Challenges Facing Industrial Organizations Ashford laid out six key challenges facing industrial organizations today: 

Legacy and insecure systems  Lack of visibility or asset inventory  Third-party or vendor access  Session control and monitoring,   Operational and availability constraints  Segmentation and lateral movement risk  Each of these resonated with our audience—and Ashford connected them directly to real-world industrial operations, noting when remote access fails on any one of these fronts, what should be an enabler quickly becomes a liability. 

Underlining this urgency, Ashford referenced the Cybersecurity and Infrastructure Security Agency (CISA)’s alert that threat actors continue to exploit internetaccessible OT/ICS devices.  

This set the tone: industrial operators must assume exposure and rethink how access is managed and monitored.

This is more than technical nuance. It is foundational to their mission. 

Finding the Right Solution  Ashford didn’t stop at the problem; he outlined what a mature SRA solution must deliver:  

Strong, contextaware authentication;   Protocol isolation and filtering  Continuous monitoring including session recording and realtime intervention  Resilience with high availability and failover  Integration with identity providers, policy engines, vaults, and monitoring platforms  Legacy protocol support  Central governance at scale  Auditability for compliance   With this background, he turned his focus towards how SRA solutions are evolving, and laid out the top trends, including: Zero Trust access and leastprivilege enforcement; addressing IT/OT convergence, microsegmentation, and machine-to-machine/non-human access, among others.

As he walked through this evolution, it became clear to our audience that SRA isn’t just about providing remote access—but should be a comprehensive solution central to a successful industrial cybersecurity strategy. 

Of particular interest to our audience was Ashford’s commentary on how our PrivX OT solution stands out, and how its capabilities address many of the six core challenges he had walked through earlier.

Especially in environments where legacy equipment, remote third-party access, and stringent uptime demands collide: 

 

Modern microservices architecture  Browser-based UI  Flexible deployment (on-prem, cloud, Kubernetes, airgapped)  Support for passwordless and keyless access with ephemeral certificates  Justintime and justenough access  Microsegmentation  Session recording  Asset discovery  Integration with major identity and IAM systems  As the session wrapped up, the tone was optimistic and actionable. SRA for OT/ICS is no longer optional. It’s an operational and strategic enabler.

His presentation underscored the call to action: if you’re responsible for secure remote access in industrial environments, now is the moment to move beyond mere tunneling.

It’s time to embrace context-aware access, industrial-grade SRA, visibility from edge to command center, and a future where credentials don’t define your security posture—they support it.
