Critical infrastructure AI is now an OT control surface.

Tokto puts every prompt your control room operators, field engineers, scheduling teams, and vendor-shared AI tools run, every model output that touches a substation, a pipeline, a grid asset, or a port manifest, under one auditable trail FERC, NERC, TSA, CISA, and MARSEC can read.

What you get with Tokto

• Every prompt and model output tied to an asset, an operator, a field event, a model version, and the operating state in force.
• A single audit log that satisfies NERC CIP, TSA SDs, CISA, FERC, MARSEC, and the SOC 2 auditor on the same evidence.
• Policy at the prompt: grid telemetry, port manifests, OT credentials, and ICS commands blocked before tokens leave the boundary.
• Air-gapped, on-prem inference. Raw OT data never leaves the control plane.

How it works

Tokto sits at the AI control plane of the utility and the port. Every control-room co-pilot, every field-engineer assistant, every scheduling model, every vendor-shared AI tool becomes a record at the moment of output. The record carries the asset, the operator, the event, the model version, the operating state, and the policy in force.

When CISA asks what your AI did before the incident, when NERC asks how CIP-005-7 applied across an AI integration, when MARSEC asks how port manifests were governed, the answer is one query against the system of record. The CISO controls one trail across IT, OT, and AI.

What goes wrong without it

• A Port of Seattle-class ransomware event hits a vendor AI integration. The Port cannot say what the model touched before isolation.
• A CIP-013-2 supply-chain incident through an AI co-pilot. No record. NERC violation per occurrence.
• An operator pastes a grid topology into a public LLM. Foreign-actor exposure in 48 hours.
• A port-side carrier AI integration leaks manifest data. State and federal agencies open joint inquiries.
