Astaara, a Guernsey-based provider of integrated insurance services and risk management advisory, has announced an increase in its cyber policy limit to US$27.5 million and confirmed that its underwriting security now holds a rating of A- or better.
The company’s underwriting capacity has risen from US$25 million in April 2023 to US$27.5 million. This development extends Astaara’s offering to maritime operators, offshore marine contractors, shipowners, ports, and terminals globally.
Astaara’s A- or better rating is applied across its capacity and is supported by Liberty Mutual Insurance Company, the lead partner in the programme.
Astaara’s cyber insurance model does not exclude risks classified as terrorism or state-backed, offering broader cover for clients.
Robert Dorey (pictured above), group CEO of Astaara, said, “With this larger and higher quality capacity, we reaffirm our leadership in marine cyber risk underwriting. Our clients now benefit from higher limits backed by top-tier underwriting capacity.
Dorey also noted that Astaara works closely with clients to build cyber security maturity and supports them during claims.
Astaara’s integrated service includes cyber risk advisory, underwriting, and real-time analytics, serving the marine, offshore, and port sectors.
The expansion of Astaara’s underwriting capacity and the A- or better rating follows previous increases from US$12.5 million in 2020 to US$25 million in April 2023. The firm also received investment from the West of England P&I Club in 2020.
The announcement comes at a time when the UK is experiencing a significant escalation in cyber threats. According to the National Cyber Security Centre’s (NCSC) latest annual review, there was a record 204 nationally significant cyberattacks in the 12 months to August 2025, up from 89 the previous year – a 129% increase.
Of these, 18 incidents were classified as highly significant, with the majority attributed to advanced persistent threat actors, including both nation-state groups and sophisticated criminal organisations. The NCSC noted that this marks the third consecutive annual increase in high-severity cases, and that the volume and sophistication of attacks targeting the UK’s digital infrastructure is rising rapidly.
