Two Tiers of Trust

Industrial AI buyers evaluating a vendor today are really evaluating two different things wearing one label. One is the control layer underneath the AI. The other is the AI itself. Right now, only one of them has a certification regime that means anything.

The control layer is getting measurably better evidence behind it. ODVA’s CIP Security recently achieved IEC 62443-4-2 SL-C 3 certification, a component-level, third-party-verified security rating under a named standard and a named security level, not a vendor’s self-description. That kind of certification does not happen in isolation. The assessment ecosystem behind it is also expanding: Abbott Risk Consulting recently joined ISASecure specifically to strengthen adoption of ISA/IEC 62443, which means more capacity to certify more control systems against a consistent bar, and more vendors with somewhere to go to get that proof.

The AI and embodied-AI layer sitting on top of that control infrastructure has no equivalent. ASTM and the Singapore Standards Council have identified five specific gaps holding back embodied AI, a direct acknowledgment from standards bodies that the testing and assurance infrastructure for the AI layer itself is still unresolved, at the same moment the control layer underneath it is accumulating real certificates. That is not a timing coincidence buyers should wave off. It is the gap.

The gap matters more because the threat surface above both layers is moving. Industrial cybersecurity commentary has turned specifically to securing AI-powered industrial applications and autonomous agents, a shift from agents that advise to agents that act inside operational environments. Fortinet’s Korea OT security summit framed this starkly, warning that AI factories are widening the hacking risk across connected industrial environments, with a parallel framing of the same event noting the summit’s focus on AI’s expansion of OT attack surface. The uncertified layer is the one sitting closest to that expanding risk.

For buyers, the diligence shifts from asking whether a vendor is compliant to asking which half of the stack the compliance actually covers. Ask for the certificate, the standard, the component or protocol it applies to, and the security level, the way ODVA can produce one for CIP Security. Then ask directly what equivalent third-party certification exists for the AI or embodied layer itself, and be prepared for the honest answer, which right now is usually none, because the standards bodies writing the rules say that infrastructure is not built yet.

A control certificate proves something specific and auditable. An AI vendor’s confidence in its own model proves nothing beyond itself until a standard like the ones ASTM and Singapore are still assembling exists to test it against. Buyers who treat those two claims as equivalent are the ones who will discover, later and expensively, that they were not.

Chair · Editorial Judgment	Claude	cleared. The argument is structurally sound—control layer has verifiable certification, AI layer does not, buyers should distinguish between them—but the claim that this asymmetry is ‘the gap’ overstates what
