TL;DR: Secure remote access for OT systems is now available on Nokia’s MXIE edge platform, combining zero trust, just-in-time access, role controls, approvals, and session monitoring for industrial and CPS environments, according to SSH Communications Security. The real issue is not the platform pairing, but whether industrial teams can govern privileged access tightly enough to reduce attack surface and satisfy audit demands.
NHIMG editorial — what this means for NHI practitioners
By the numbers:
- 25% of Fortune 100 companies rely on SSH’s solutions.
- Systems with least-privileged AI access had a 17% incident rate vs 76% for over-privileged systems.
- Only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security.
Questions worth separating out
Q: How should security teams govern remote privileged access in OT environments?
A: They should treat OT remote access as privileged access governance, not simple connectivity.
Q: Why does just-in-time access matter for industrial control systems?
A: JIT access matters because industrial systems are often accessed by operators, engineers, and third parties who do not need permanent credentials.
Q: What breaks when OT access approvals are not linked to the access grant itself?
A: When approvals are disconnected from the actual access grant, the organisation may have paperwork but not control.
Practitioner guidance
- Tie privileged access to work orders Require every OT remote session to be linked to an approved maintenance ticket or change record before access is issued, and revoke it automatically when the job closes.
- Enforce task-scoped JIT access Issue credentials only for the duration and scope of the approved industrial task, with no reusable standing entitlements for vendors or support teams.
- Record full privileged sessions Capture session metadata, identity attribution, commands, and credential use so investigators can reconstruct operator activity after an incident or audit.

Privileged OT remote access remains a standing-privilege problem disguised as connectivity. The industrial edge does not change the core governance issue: third parties and operators still need elevated reach into assets that cannot tolerate broad trust. Zero trust and JIT matter here because the risk is not access itself, but access that persists beyond the task boundary. Practitioners should treat OT remote access as privileged access governance, not infrastructure convenience.
A few things that frame the scale:
- Systems with least-privileged AI access had a 17% incident rate vs 76% for over-privileged systems, according to the 2026 Infrastructure Identity Survey.
- Only 13% of organisations feel extremely prepared for the reality of agentic AI despite the majority racing toward autonomous adoption, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: Who is accountable when a privileged OT session is misused?
A: Accountability should sit with the organisation that owns the access policy and the operational process, not with the session log alone. If approvals, ticketing, identity attribution, and session recording are not integrated, responsibility becomes blurred across IT, OT, and third-party support teams. Governance only works when the access chain is owned end to end.
