What this domain asks
The decision boundary connecting cyber defense with process safety, functional safety, reliability, operations, maintenance, engineering change, and physical consequence.
The domain should retain its own evidence, decision owner, materiality criteria, exception path, and consequence even when it shares organization identity, workflow, or technology with adjacent domains. Aggregation can support oversight; it should not erase the evidence behind different risks or operating outcomes.
Buyer questions
- Which cyber action can alter view, control, timing, redundancy, trip, alarm, interlock, protection, or recovery?
- Who reviews and authorizes collection, scanning, endpoint, network, identity, patch, and response changes?
- How are safety systems, basic process control, electrical protection, and auxiliary systems separated and coordinated?
- Can cyber and engineering teams share asset identity and evidence without confusing their accountabilities?
- How are near misses, anomalies, incidents, and exercises used to improve both defensive and operating controls?

Evidence boundary
OT Defense Review is not a regulator, standards body, certification body, control-system integrator, safety authority, engineering firm, incident-response provider, insurer, or law firm. Its records support market research and decision review; they do not establish compliance, certification, security, safety, reliability, exploitability, or fitness for a specific operational environment. A provider's documented capability can identify a research candidate but cannot establish buyer-specific adequacy for this domain.
