Since 2024,
maritime cybersecurity
is no longer optional
— it is essential.

In 2024, IACS introduced technical standards UR E26 and E27 to enhance cyber resilience in ships. The following year, in 2025, IMO released a revised guideline (MSC-FAL.1/Circ.3/Rev.3), recommending comprehensive cybersecurity measures across the entire vessel lifecycle.

Cybersecurity is now essential—not optional—demanding more systematic and proactive responses across the maritime industry. However, these standards cover every phase from design to operation and maintenance, and include extensive requirements that require thorough preparation for effective implementation.

What are IACS UR E26 and E27?

IACS UR E26IACS UR E27DefinitionAn international regulation requiring the integration of cybersecurity from the design and construction stages of newbuild vessels.

It aims to ensure cyber resilience by securely integrating IT (Information Technology) and OT (Operational Technology) systems into the ship's network and complying with measures for identifying, protecting against, detecting, responding to and recovering from cyber threats.An international regulation requiring onboard assets to be equipped with cybersecurity capabilities.

It supports the overall E26 security architecture through technical requirements such as authentication, access control and encryption.Applicable
