UK Maritime Cybersecurity: Vendor Evidence
UK maritime vendor cybersecurity matters whenever a supplier connects a laptop, sensor, remote-support tool, software update or storage device to a vessel or shore system. The vendor should be able to explain what access is required, how it is controlled and how it ends.
This is operational guidance, not a substitute for a vessel-specific cyber risk assessment.
What cybersecurity evidence should a marine vendor provide?
Provide the service data flow, required access, authorised devices and people, software controls, transfer method, incident route, retention period and access-removal process. Tie every answer to the actual service.
The UK government's ship cyber security code of practice gives owners, operators and related stakeholders a framework for managing maritime cyber risk. Vendors should use the current official guidance when aligning their own controls.
Map the service connection
Draw a simple flow from vendor equipment to vessel or shore systems. Identify read-only and write access, network segments, remote connections, removable media and cloud services. Mark where credentials or operational data cross organisational boundaries.
A diagram often exposes assumptions hidden by the phrase “remote diagnostics”.
Control people and devices
State how technicians are authorised, trained and removed from access. Explain device hardening, malware protection, patching and approval of tools used onboard.
If subcontractors participate, identify who verifies their controls. Responsibility does not disappear when a specialist is introduced.
Explain software and update assurance
Describe how software origin, integrity and version are checked; who approves an update; how rollback is considered; and what record is left after the work. Separate OEM-controlled actions from vendor-developed software.
Do not publish sensitive configuration detail. Publish the governance that tells the buyer the detail exists and is controlled.
Define incident and close-out steps
Give the vessel or client a named escalation route and required first information. State how access tokens, temporary accounts, copied data and diagnostic files are removed or retained after completion.
Close-out evidence might include access logs, installed version, test result and confirmation that temporary connectivity was disabled.
Put evidence beside the service
Do not bury cyber controls in a generic policy page. Link the relevant assurance directly from remote monitoring, navigation, automation, communications or software services.
Creatif Work builds marine websites and digital-service explanations that procurement, operations and cyber teams can inspect together. Through our custom software service, we also help firms design controlled client workflows rather than exposing operational data through improvised forms and file transfers.
