What Landguard Systems does

Landguard Systems is a UK-based specialist designer and manufacturer of custom radio systems, founded in 2006 and headquartered in Fareham, Hampshire, with a US subsidiary (Landguard Systems Inc.) operating from Tampa, Florida. The company serves government, defence and law enforcement customers globally, delivering bespoke radio systems built around Software Defined Radio (SDR) technology implemented on open industry standards — notably OpenCPI and OpenVPX. Its product portfolio centres on intelligence, surveillance, target acquisition and reconnaissance (ISTAR) solutions, small-form-factor SDR transceivers, and Blue Force and Red Force tracking devices that operate across multiple bearers including Iridium and Kinéis satellite networks, cellular and conventional RF.

The business model combines custom hardware sales with a recurring services annuity. Landguard sells bespoke radio systems via direct enterprise sales to government and defence customers, supplemented by after-sales support covering 24/7 operational assistance, planned maintenance, training programmes, and satellite airtime services for Iridium and Kinéis networks. Pricing is quote-based and not publicly disclosed. Go-to-market relies on direct enterprise field-sales teams in both UK and US offices, with brand visibility generated through major defence, security and law enforcement exhibitions including Milipol Paris, Security & Policing, SOF Week, GPEC, and Police Security Expo.

In June 2025, Chemring Group announced a conditional acquisition of Landguard Nexus Limited (the parent holding company), bringing approximately 30 specialist engineers into Chemring's Roke business. The transaction is positioned to merge Landguard's modular SDR expertise with Roke's Cyber and Electromagnetic Activities (CEMA) capabilities, creating a UK sovereign portfolio spanning defence, national security and law enforcement. The deal was pending UK National Investment and Security Act approval at the time of disclosure.
