Threat Briefings

In-depth analysis of emerging maritime cyber threats — GPS spoofing, crew network attacks, OT malware campaigns, and vendor vulnerabilities affecting shipboard systems.

Playbook & Vault updates

Notifications when new playbooks, vault forms, or compliance guides are published — so your vessel documentation stays current with the latest E26, IMO, and BIMCO guidance.

Regulatory & industry news

Updates on IACS UR E26/E27 developments, IMO circulars, BIMCO guideline revisions, and Class Society cyber notation changes that affect vessel compliance programmes.

CVE alerts for maritime OT

Critical vulnerability advisories filtered for maritime-relevant equipment — navigation systems, power management, vessel automation, and ICS components used in shipboard environments.

Publishing frequency

Threat Briefings are published as significant threats emerge — typically 2–4 per month. Playbook and regulatory updates are sent as published. You will not receive daily emails.

Who writes this

All content is written by ETOs and automation engineers with direct experience of IACS UR E26 newbuild programmes and fleet cyber compliance — not generic security researchers.

No paywalls on briefings

All Threat Briefings are free to read on the site. The subscription sends you a notification so you do not miss a new publication — nothing is hidden behind the subscription.
