CYTUR has released a new response guide and a series of sector-specific checklists to provide immediate tools for regulatory compliance and help maritime organisations to improve their cyber resilience.
The 2026 Maritime Cyber Security Standard Response Guide: From Framework to Action provides a four-stage cyclical framework consisting of framework establishment, continuous monitoring, incident response, and post-incident recovery.
The guide is intended for Chief Information Security Officers (CISO) and provides playbooks to help shipping lines, shipyards, and equipment makers comply with the International Association of Classification Societies (IACS) Unified Requirement (UR) E26 and E27.
The playbooks within the guide offer time-sequenced protocols for scenarios including Global Positioning System (GPS) spoofing, Operational Technology (OT) ransomware, and attacks on autonomous vessel Artificial Intelligence (AI). These protocols define specific actions for crews and shore-based teams starting from the first five minutes of an incident to ensure a coordinated response.
Alongside the guide, the company has also released a series of self-diagnosis checklists tailored for shipping lines, shipyards, and Original Equipment Manufacturers (OEM). The checklists cover seven domains and 28 items, allowing organisations to grade their current security posture. Based on the results, the system provides improvement roadmaps with specific actions to be taken at 30-day, 90-day, and six-month intervals.
The Shipping Lines edition of the threat brief series highlights risks such as data theft and communication blackouts, referencing the grounding of the MSC Antonia in May 2025 following GPS spoofing. The Shipyards and OEM editions focus on upstream risks, such as design data theft and the potential for a single manufacturer breach to affect multiple fleets simultaneously.
The release follows the company’s publication of its 2026 Maritime Cyber Threat White Paper in February of this year.
