Cyber security for shipping lines

Bookings, documents and fleet systems span many countries, and depend on every terminal you call at.

Your cyber risks

What public sources say about shipping lines

Each card links to its source. We kept only what the sources say.

One outbreak, the whole group
In June 2017 the NotPetya malware hit A.P. Moller-Maersk; the group said it mainly hit Maersk Line, APM Terminals and Damco. The malware did not target shipping.
A regional network down
In July 2018 COSCO Shipping Lines reported a network breakdown in its Americas region, with e-mail and telephone hit at several U.S. sites.
Cyber risk in the safety system
IMO resolution MSC.428(98), adopted in June 2017, says cyber risks should be addressed in the safety management systems of ships.
NIS2 names the companies
Annex I of NIS2 lists sea and coastal freight water transport companies, not the individual vessels they operate.

Questions

Shipping lines: questions

Click a question to read the answer.

Yes. Any organization in the port chain can join: terminals, port authorities, marinas, oil and gas ports, shipping lines, hauliers, freight forwarders and the industrial shippers that depend on them. Start with the launch offer.

Annex I of Directive (EU) 2022/2555 lists inland, sea and coastal passenger and freight water transport companies, not including the individual vessels they operate. Large and medium-sized companies are generally in scope; check your country's law. Read our NIS2 page.

The current IMO guidelines on maritime cyber risk management, MSC-FAL.1/Circ.3/Rev.4 dated 28 May 2026, set six functions to run at the same time: Govern, Identify, Protect, Detect, Respond and Recover. See our best practices page.

Yes. What you share with us stays between us, and we never name a member without its written agreement.
