OT Remote Access After COVID: Why IT Tools Fail and What Critical Infrastructure Needs Now

Remote access transformed overnight - and OT environments are still feeling the impact.

In this episode of Protect It All, host Aaron Crow is joined by Steve Rutherford, VP of Sales at Hyperport and former military officer, for a candid conversation on how secure remote access in operational technology (OT) has evolved - and where it’s heading next.

They unpack how COVID accelerated remote connectivity across critical infrastructure, why many traditional IT security tools fall short in OT environments, and what protection really looks like when safety, reliability, and uptime are non-negotiable. Drawing from military discipline and frontline OT experience, Steve shares a grounded perspective on managing risk in environments where failure has physical-world consequences.

You’ll learn:

How COVID permanently changed OT remote access expectations
Why IT-first security approaches don’t translate well to OT
The role of layered access controls and policy-driven permissions
How dynamic access and trust scoring are reshaping OT security
Where IT/OT convergence helps - and where it creates new risk
What leaders must prioritize to balance access, safety, and resilience

If you’re responsible for enabling remote access while protecting critical operations, this episode delivers real-world insight, practical guidance, and a forward-looking view of OT cybersecurity.
