Securing Remote Access in OT: Visibility, Segmentation, and What Compliance Misses

Remote access is no longer optional in OT - but unmanaged connectivity is one of the fastest ways to lose control of critical systems.

In this episode of Protect It All, host Aaron Crow breaks down the real challenges of securing connectivity across IT and OT environments. As vendors, technicians, and support teams increasingly rely on remote access, many organizations struggle with poor visibility, legacy systems, and unclear network boundaries - creating unnecessary risk.

Aaron walks through newly released secure connectivity guidance from CISA and the UK National Cyber Security Centre, translating an eight-point framework into practical, real-world steps that security and operations teams can actually implement.

You’ll learn:

Why remote access is one of the biggest OT risk multipliers
How poor visibility creates blind spots attackers love
Why asset inventory and documentation are foundational - not optional
How segmentation and least-privilege design shrink the attack surface
What compliance frameworks get right - and what they don’t
Best practices for vendor access, MFA, session recording, and monitoring
How to design secure connectivity without breaking operations

Whether you’re responsible for OT security, managing vendors, or bridging IT and OT teams, this episode delivers actionable guidance to help you regain control of connectivity and protect critical infrastructure.
