Certification affirms compliance with international cyber-resilience standards for onboard computer-based systems

SINGAPORE, Jan. 20, 2026 (GLOBE NEWSWIRE) -- iOThree Limited ("iO3" or the "Company") (NASDAQ:IOTR), a pioneering provider of digital solutions for the maritime industry, announces that V.Secure, its maritime cybersecurity system with a managed Security Operations Center (SOC), has been granted IACS UR E27 Type Approval by RINA, the international classification society. This certification confirms that V.Secure meets the IACS technical cybersecurity requirements for Computer-Based Systems (CBS) installed on board ships.

IACS UR E27 defines cyber-resilience requirements for onboard systems, covering access control, malicious code protection, event logging, communications integrity, recovery support and safe integration into a vessel's wider architecture.

V.Secure integrates Network Intrusion Detection System (NIDS), Security Orchestration, Automation and Response (SOAR), and Security Information and Event Management (SIEM) capabilities, with 24/7 monitoring from a Security Operations Centre. The solution enables early detection and rapid response to cyber threats across onboard IT and operational technology (OT) networks, even under intermittent connectivity.

"Achieving RINA's E27 Type Approval marks a key milestone, affirming V.Secure's technical integrity and operational value." said Darryl See, Chief Technology Officer, iO3. "Designed as a simplified onboard Security Operations Center, V.Secure provides continuous cyber threat monitoring and automated response in full compliance with IACS standards, giving shipowners confidence in its performance at sea."

Yong Song Pang, Executive South Asia Pacific Marine Director RINA, added, "Cyber resilience is no longer optional, it's foundational to safe and compliant maritime operations. With this Type Approval, iO3 will be able to strengthen maritime cybersecurity and support vessel safety through robust and secure systems. This milestone not only strengthens our shared commitment to enhanced connectivity but also paves the way for contributing significantly to the future of autonomous, smart ships."

V.Secure goes beyond strict regulatory compliance. In addition to meeting E27 Type Approval standards, it strengthens shipowners' broader cybersecurity programs aligned with IMO 2021 guidelines and company policies, providing real-time threat detection, reporting, and protection optimized for maritime environments with limited connectivity.
