Your integrators, OEM support engineers and the HVAC vendor all have a way in. Who used it last night?
Privileged access controls rarely reach past the industrial DMZ. Deploying them on OT systems is the barrier, because controllers cannot run security agents and operators cannot wait for a login during a process upset. That leaves vendor access on always-on VPNs, shared jump hosts and credentials nobody rotates.
When privileged access fails in OT, the result is a stopped line or a safety incident, not a data breach. Regulators and cyber insurers have noticed. They now ask for proof of who did what on every session that crosses into OT.
Securing OT Access at the Boundary shows how to bring vaulting, multi-factor authentication (MFA) and session recording past the industrial DMZ. Nothing installed on controllers. No downtime. No waiting at 2 a.m.
Read the whitepaper to learn how to:
- spot the six gaps that let intruders in, and the five questions that reveal yours.
- secure every Purdue layer without touching a protected device.
- build an emergency path faster than the workaround, with MFA and recording still on.
- govern the AI agent in your OEM's engineering software as the newest identity on site.
- start with seven controls ranked by impact and four numbers for your board.
Networks stay segmented. People, machines and vendors don't.
Now see how to govern identity, the one thing that crosses every boundary.
