CISA partners publish Secure by Demand guidance for OT buyers

What the source establishes

The guide is dated January 13, 2025. It addresses priority considerations for OT owners and operators selecting digital products. The source includes buyer questions on configuration, logging, open standards, ownership, secure communications, updates, vulnerability handling, and support. OT Defense Review records the named source, date, status, affected market layer, and evidence class separately so an announcement, authority record, or provider study is not silently converted into an independently verified operating conclusion.

The guide supplies selection considerations; it does not certify a product or establish that a provider has met them. The maintained record distinguishes the fact of the publication or event from forward-looking statements, provider characterization, later implementation, and conditions that the source does not establish.

The industrial-defense consequence

Procurement teams need versioned requirements and evidence that survive the handoff from selection to architecture, validation, acceptance, operation, maintenance, incident response, renewal, and end of support. Product security becomes a lifecycle responsibility shared across supplier and owner roles.

The practical review should follow the change into system boundaries, accountable roles, asset populations, architecture, data collection, access, detection, response, recovery, provider dependencies, retained evidence, and the operating constraints that could alter safety or reliability. That is where a headline becomes a defensible program decision.

What asset owners should test next

Use one representative product and request current security documentation, secure defaults, identity model, logging, data flows, update and recovery behavior, support dates, vulnerability process, component evidence, remote-access model, export, and contractual commitments. Mark documentation, demonstration, contract, test, and unknown separately.

Provider responses still require direct validation and may vary by product, version, service, deployment model, and contract. Preserve which facts came from the authority or organization, which behaviors were independently observed under a disclosed method, which depend on configuration or services, and which remain not established. Do not use a public article as authorization to probe, scan, block, patch, isolate, or reconfigure a live industrial environment.

Enterprise buyer test

Translate this change into the exact population, record type, workflow stage, decision owner, effective date, and evidence that could be affected. Ask current or prospective providers to demonstrate the named workflow with representative data and an exception—not a polished feature tour. Record what official documentation establishes, what a provider states, what the team observes, and what remains unresolved.

A defensible review also identifies the dependency outside the product. Authority interpretation, policy configuration, data quality, integrations, human judgment, approval rights, release governance, training, and retained evidence may remain customer or service responsibilities. The evaluation should preserve those boundaries instead of treating a technology claim as the complete operating model.

What we will watch next

OT Defense Review will watch the named source and affected market records for later evidence that changes status, scope, availability, implementation timing, workflow consequence, or the limits of the initial report. A later announcement does not silently overwrite this dated account; the change ledger preserves the sequence.
