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.
Card required. Cancel before day 7 and you pay nothing. Questions first? Talk to us.

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.

How an inspection goes with VesselMark
The record is built during the year, so inspection day is a matter of handing it over.
01
Evidence goes in as the work happens
Drill records, training sign-in sheets, certificates and logs are uploaded against the control they support. Each file is content-hashed and kept in write-once storage.
02
Gaps show up before the inspector
Each vessel shows what is done, due and overdue in plain English, and reminders email your team before a drill, review or renewal lapses.
03
Build the packet
Export the inspection packet for a vessel: an index of your controls and the evidence behind them, as a point-in-time snapshot.
04
Attach it to your Plan or SMS
Hand the packet over with your TSMS, SMS or Cybersecurity Plan. It supports the system you run; we do not write, certify or file it.
05
Show nothing was changed
The packet lists each evidence file with its hash, so anyone can check that the copy in front of them is the one that was stored.
See it on a real workspace with fictional vessels: open the live demo and download a packet. No account needed.
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 in transit · 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. Card required. Cancel before day 7 and you pay nothing.
