PUBLIC
Maritime OT Watch
Source-backed CISA ICS, KEV, EPSS, vendor, and U.S. maritime regulatory intelligence. Built for discovery and prioritization—not facility applicability.
watch.tidecairn.com →MARITIME OT DECISION INTELLIGENCE
Know what applies.
Prove why.
Tidecairn Systems builds local-first decision intelligence for maritime operational technology: exact product and version applicability, evidence debt, current exploitation context, and reviewer-ready proof.
No inventory upload. No autonomous applicability decisions. No active OT scanning.
TWO SURFACES · ONE EVIDENCE MODEL
Public signal. Private decision.
PRIVATE
TIDECAIRN Watchtower
A local-first assessment workstation for exact identity and version applicability, Critical IT/OT designation, evidence debt, KEV traceability, assessment workflow, and proof generation.
Request a controlled validation →WHY IT EXISTS
The costly part is not finding an advisory.
Exact applicability
Separate vendor, product, version, configuration, and evidence sufficiency instead of collapsing them into one binary answer.
Provenance
Keep the source, decision path, evidence state, and reviewer rationale bound together.
Evidence debt
Show what must still be collected before an assessor can defend a disposition.
Local-first
Facility inventory and assessment evidence stay under the operator or assessor's control.
ASSESSMENT PARTNER VALIDATION
Use it on work you already understand.
For maritime cybersecurity assessment firms, Tidecairn offers a controlled paid validation using a historical, synthetic, or appropriately redacted engagement. The objective is simple: determine whether Watchtower makes applicability analysis, evidence tracking, and reviewer-ready proof materially faster and more defensible.
Best first fit
- MTSA / Subpart F assessment teams
- Port and terminal cyber-risk consultancies
- Maritime OT assessment practices
- Operators with repeatable multi-vessel or multi-facility evidence workflows
OPERATING PRINCIPLES
Source-backed. Public-source claims retain provenance and freshness state.
Human authority. Watchtower supports assessment decisions; it does not invent them.
Fail closed. Missing or ambiguous identity cannot become “confirmed not affected.”
Evidence before confidence. Uncertainty is recorded rather than hidden.
