What Dualog does

Dualog is a Norwegian maritime software company founded in 1994 in Tromsø, providing purpose-built connectivity, communications, and cybersecurity software for commercial shipping fleets. Its core platform, the Dualog Connection Suite, runs on more than 5,000 vessels worldwide and bundles a set of modules addressing the specific constraints of ship-shore data exchange over intermittent satellite links: Dualog Mail (maritime email with unlimited accounts and audit trails), Dualog Drive (automated file transfer and IoT data collection with carrier awareness, compression, and breakpoint restart), Dualog Quota (fair-share internet management across Starlink, VSAT, and 4G), Dualog Endpoint (onboard device protection via ESET), Dualog Identity (SSO/identity management with SAML, SCIM, and OpenID), and supporting tools such as Dualog Portal, Dualog Fetch (syslog collection), and the Crew Connection mobile app. The company is expanding into adjacent areas such as DNS-based cybersecurity, identity management, and team collaboration chat.

The platform is sold on a per-vessel monthly subscription with unlimited user accounts, supplemented by optional add-ons (Malware Scanner, DNS Protection). The go-to-market is enterprise field sales to shipping companies and third-party ship management firms, supported by free trials (typically 2-4 ships for 1-3 months), webinars, and a presence at major maritime events (Posidonia, Singapore Maritime Week, Nor-Shipping). Dualog monetizes through module attach and integrations with the broader maritime IT stack, including Microsoft SharePoint, AWS S3, and the major crew management systems (Compas, Adonis, Unisea). The company is privately held, incorporated in Norway as Dualog AS, and operates from offices in Tromsø, Oslo, Hamburg, Leer, Singapore, and Athens, serving shipping customers globally.

Scale indicators8 records

Recent moves6 records

Expansion highlights6 records

Emerging players

• ABS (American Bureau of Shipping): ABS is a classification society increasingly offering cybersecurity, asset integrity and digital fleet services. Comparable to Dualog in the maritime cybersecurity and digital operations adjacency, particularly as cyber compliance is becoming mandatory.
• OTAVA (formerly StormGeo / DTN): StormGeo, folded into DTN's maritime division, provides weather routing, vessel performance and fleet IT software to commercial shipping. Comparable where its onboard software and data services overlap with Dualog's Drive and connectivity-management scope.

Broad incumbents

• Inmarsat (Viasat): Inmarsat, now part of Viasat, is the dominant global mobile satellite operator serving maritime. It overlaps with Dualog as a connectivity, network and cybersecurity provider to fleets, but at vastly larger scale and as part of a broader satellite portfolio.
• Iridium Communications: Iridium provides global satellite voice and data services including the Iridium Certus maritime portfolio, often with ship-IT partners. Comparable as a maritime communications backbone that competes and partners around the connectivity layer Dualog also relies on.
• Kongsberg Maritime: Kongsberg Maritime supplies integrated automation, bridge and digital infrastructure to commercial vessels and offshore. Comparable to Dualog where its digital ecosystem includes ship-shore data exchange and vessel IT, but it is a much broader marine-technology vendor.
• Wärtsilä Marine (Voyage & Operations): Wärtsilä's marine portfolio spans engine, propulsion and digital fleet operations including navigation, route optimization and onboard IT. Comparable where its digital layer competes with Dualog on ship-shore data, cyber and crew applications as part of a full ship-systems package.
• Orange Business (Maritime): Orange Business Services provides managed connectivity, cyber and cloud networking to shipping operators globally. Comparable to Dualog as a managed maritime IT and cybersecurity vendor, but operating at far larger scale across multiple verticals.

Direct peers

• Marlink: Marlink is a direct competitor, providing managed satellite connectivity and IT/cyber services to ship operators. Like Dualog, it bundles ship-shore networking, email, cybersecurity and crew-welfare solutions for commercial fleets, making it the closest one-stop-shop rival.
• Speedcast: Speedcast is a direct competitor delivering connectivity, network management and crew-welfare solutions to maritime, energy and enterprise customers. Overlap with Dualog is strongest in managed ship-shore communications and cyber for commercial fleets.
• KVH Industries: KVH provides maritime VSAT connectivity plus onboard IT services such as email, training, content and operations tools. Comparable because KVH competes with Dualog at the ship-IT layer even when bandwidth is delivered separately.
