What GTMaritime does

GTMaritime (legal entity: Global Technology Ltd, registered in England and Wales, company number 3657237) is a privately held maritime IT and cybersecurity software company founded in 1999 and headquartered in Warrington, United Kingdom. The company operates as a subsidiary within the Valstone Group and maintains regional offices in Singapore and Piraeus, Greece, supporting global maritime fleet operators. With over 25 years of maritime experience, GTMaritime delivers a portfolio of six core software products — GT Mail (maritime-optimised email), GT Replicate (automated file transfer and data synchronisation), GT Identify (fleet-wide IT asset visibility and vulnerability scanning), GT Sentinel (ESET-powered maritime antivirus), GT Aware (human risk management and security awareness training), and CrowdStrike via GTMaritime (enterprise-grade endpoint detection and response) — all delivered as cloud-hosted, software-only solutions requiring no onboard hardware.

All products are purpose-built for the constraints of maritime satellite environments, including intermittent connectivity, low bandwidth, and the need to support GEO, LEO, and L-band satellite providers. Technical differentiators include up to 90% email compression, automatic resumption of interrupted transfers up to 33GB, offline endpoint protection, CVE-aligned vulnerability scanning, and time-of-click URL protection (Link Check). The platform integrates with Microsoft 365, SharePoint, AWS S3, PMS, IoT systems, ECDIS charts, and CCTV/video systems, enabling ship-to-shore data flows across distributed fleets.

GTMaritime generates revenue through per-vessel annual software subscriptions, targeting enterprise fleet operators across all vessel types (tankers, bulk carriers, container ships). The company serves 2,000+ ship owners and 17,000 vessels, processing over 1 million emails daily and stopping 125,000 cyber threats monthly. Distribution combines direct enterprise field sales with a channel partner network that includes Zener (Zener Onenet) and major satellite and communications providers such as Singtel, KDDI, SIRM, and Hellenic Radio Services. The company holds ISO 27001 information security accreditation and operates a 24/7 ITIL-trained support function, contributing to a reported NPS of 74 and average support resolution time of 78 minutes.

Direct peers

• Navarino: Navarino is a maritime IT and communications company offering connectivity, email, file transfer, and cybersecurity solutions to ship owners and operators globally. It is the closest direct competitor to GTMaritime, with overlapping product categories (maritime email, fleet IT management) and a similar per-vessel subscription model targeting the same enterprise fleet operators.
• Speedcast: Speedcast provides managed connectivity, IT, and network services to maritime, energy, and enterprise customers, including cybersecurity overlays for vessels. It is comparable to GTMaritime as a provider of ship-to-shore communications and managed IT services sold per-vessel to global fleet operators.
• NSSLGlobal: NSSLGlobal is a satellite communications and IT services provider for maritime, government, and enterprise customers, offering managed connectivity and cyber solutions to fleet operators. It is a direct competitor in delivering maritime IT and cybersecurity subscriptions to ship owners alongside satellite connectivity.
• KVH Industries: KVH delivers satellite communications, VSAT, and value-added services including content and operational tools to commercial maritime fleets. It competes in the same ship-to-shore connectivity and vessel-IT space as GTMaritime, supplying enterprise shipping companies with subscription-based connectivity solutions.
• Marlink: Marlink is a major maritime IT, connectivity, and cybersecurity provider serving commercial shipping and offshore with managed communication services. It competes head-to-head with GTMaritime in vessel email, file transfer, and endpoint security delivered over satellite links to enterprise fleet customers.

Broad incumbents

• Thales Group: Thales is a large aerospace and defence incumbent with maritime cybersecurity offerings (including fleet cyber protection and IMO-compliance tooling) alongside its broader portfolio. It is comparable to GTMaritime in maritime cyber risk management and compliance reporting, but competes from a much broader enterprise and defence platform rather than as a maritime IT specialist.
• Inmarsat (Viasat): Inmarsat, now part of Viasat, is a global satellite communications incumbent offering Fleet Xpress and Fleet Secure for maritime operators, including cybersecurity add-ons. It competes with GTMaritime indirectly by bundling connectivity with security and IT services, but operates at the network layer rather than as a maritime IT software specialist.
• Iridium Communications: Iridium provides global L-band satellite communications, including the Iridium Certus maritime service, with partner-built value-added applications. It is comparable to GTMaritime as part of the maritime connectivity ecosystem serving enterprise fleets, though it sells underlying bandwidth rather than specialised IT/cybersecurity software.
