Maritime compliance · coastal & inland
Stay inspection-ready without a compliance department.
VesselMark turns the rules your vessels answer to — Sub M / TSMS, USCG cyber, IMO, NIST, ISO 27001 — into plain-English controls you pick and choose, keeps your evidence tamper-proof, and emails you before anything lapses. Documentation-first — no sensor, no SOC.

We keep you on track
Staying on top of controls is the hard part. So we do it.
Drills, log refreshes, patch cadence, annual reviews — VesselMark schedules them, tracks what's due, and emails your team before anything slips. You see exactly what's outstanding in plain English, and your readiness updates the moment you close a gap.
The product
Compliance management, not a science project.
Documentation-first. No shipboard hardware, no network agents, no 24/7 monitoring obligation — just a clear, defensible record of where each vessel stands.
Choose the modules you need
Sub M / TSMS, USCG cyber, IMO, NIST, ISO 27001 — turn on the frameworks your vessels actually answer to, and add more as your obligations grow.
Learn more →Do the work once
One control can satisfy several frameworks at once. Map it once; see credit everywhere it applies across the modules you run.
Plain-English controls
Every control has a plain-language title and guidance — see what's outstanding without a cybersecurity degree.
Tamper-evident evidence
Documents are content-hashed and held in write-once storage, so your evidence trail stands up to scrutiny.
One-click inspection packet
Export your posture and evidence index for a PSC, USCG, or class review — a defensible point-in-time snapshot.
Sits beside Helm CONNECT
Helm and TBS stay as daily ops, maintenance, crew, and Sub M recordkeeping. VesselMark is the documentation and evidence layer.
Learn more →Built to be trusted
We run our own controls against ourselves.
Enforced multi-factor auth · strict tenant isolation · write-once evidence + append-only audit trail · encryption at rest · least-privilege throughout.
Pricing
Simple, per vessel, per month.
Coastal or inland, four boats or thirty — pay for what you run. No per-user tax, no “book a demo to see the price,” no renewal surprises. 14-day free trial, no card required.
