MarineGuard

What MarineGuard does

MarineGuard Systems Limited is a privately held UK security integrator founded in 1998 and headquartered in Southampton. The company designs, engineers, installs and maintains bespoke integrated security systems for assets at the land-water boundary, serving four sectors: superyachts, ports and terminals, refineries and industrial sites, and commercial shipping and offshore (vessels, rigs, FPSOs). All work is delivered by MarineGuard's own security-cleared engineers with no subcontractors, under bespoke quote-based pricing on multi-year engagements.

The company's core technology is a proprietary Command and Control (C2) software platform developed entirely in-house, which fuses long-range polarimetric radar (12nm+), AIS, 360° throughhull diver detection sonar (900m), RF + radar drone detection (1.7km) and disruption (500m), PTZ/thermal/panoramic cameras with AI analytics, and multi-modal access control (biometric, card, fob, Bluetooth, NFC, keypad) onto a single operational map. The platform is SAPIENT-compliant (BSI Flex 335, the UK Ministry of Defence's open interface standard), supports on-premise deployment with data kept on site, and includes event-driven camera auto-cueing and look-back. MarineGuard also delivers the full ISPS certification pathway for port facilities.

The revenue model combines one-time bespoke design, hardware and installation revenue with recurring maintenance and support contracts, supplemented by professional services (survey, risk assessment, consultancy, training) and ISPS compliance work. The customer base is anchored by tier-1 superyacht shipyards including Lürssen, Feadship, Oceanco, Blohm+Voss, Heesen, Nobiskrug, CRN and Armon, with active operations spanning 14+ countries across Europe, the Middle East and further afield. MarineGuard reports more than 30 bespoke builds across vessels ranging from 40m to 140m+.

Core offering

MarineGuard designs, engineers, installs, and maintains bespoke integrated security systems for maritime and infrastructure assets such as superyachts, commercial vessels, ports, and refineries. Each system is built around a proprietary in-house Command and Control (C2) software platform that fuses radar, sonar, cameras with AI analytics, drone detection and disruption, AIS, and multi-modal access control onto a single operational map. Delivery is turnkey, with site survey, custom design, installation, training, and ongoing support carried out by MarineGuard's own security-cleared engineers.

Product overview

MarineGuard offers a unified C2 (Command & Control) platform architecture with modular detection subsystems. The core C2 Platform integrates long-range radar, 360-degree diver detection sonar, drone defence, surveillance cameras with AI analytics, and access control onto a single map interface. This platform is configured across four sector solutions: Superyacht Security (protecting private vessels 40m+), Commercial Shipping & Offshore (for vessels, rigs, and FPSOs), Refineries & Industrial (for high-consequence sites), and Ports & Terminals (with ISPS certification pathway). All systems are engineered, installed, and maintained by MarineGuard's own team, with no subcontractors.

Direct peers

• MARSS: UK-headquartered integrator of AI-driven C2 platforms for maritime and critical infrastructure security, with overlapping customer base in ports and high-value assets. Directly comparable in scope (proprietary C2 fusing sensors, drones, cameras) and end-markets.
• Kelvin Hughes (HENSOLDT): Long-established maritime radar and integrated bridge/security systems supplier, now part of HENSOLDT. Overlaps with MarineGuard's radar, surveillance and integrated bridge/security offerings for naval and commercial vessels.
• Sonardyne: UK-based specialist in underwater acoustics including diver detection sonar, positioning and maritime security. Directly comparable on the sub-surface detection layer of MarineGuard's stack (900m throughhull diver detection sonar).
• OSI Maritime Systems: Supplier of integrated bridge, navigation and tactical C2 systems for naval and commercial vessels. Comparable in delivering unified situational-awareness software fused with radar, AIS and sensor inputs on maritime platforms.
• Navtech Radar: UK-based specialist in high-resolution surveillance radar for critical infrastructure, ports and perimeter security. Comparable on the long-range radar detection subsystem that MarineGuard integrates into its C2 stack.
• Anschütz (Raytheon): Specialist in integrated bridge systems, navigation and ship security for commercial and naval vessels. Comparable in delivering a unified operational picture (radar, AIS, cameras, alarms) to vessels — directly competing for shipyard spec-ins.

Broad incumbents

• Saab (Maritime Security): Large defence prime with a maritime portfolio spanning naval radar, port security and integrated C2. Competes for the same port and high-end vessel security tenders but as part of a much broader defence offering.
• Thales: Global defence and digital identity group with significant maritime surveillance, port security and naval systems. Overlaps with MarineGuard's port, refinery and vessel security business, particularly for ISPS and high-consequence sites.
• Teledyne FLIR: Global supplier of thermal imaging, surveillance cameras and integrated security platforms with strong maritime and port security references. Overlaps with MarineGuard's thermal/PTZ camera layer and AI video analytics capability.
