Eight years ago, Halo Group Security was founded in Farnham, Surrey, on a straightforward idea: that a client should not have to assemble their own protection from half a dozen separate suppliers. Physical security, electronic systems, and cyber defence had long been treated as different disciplines, sold by different companies, and integrated, if at all, by whoever happened to be on site that week. Halo was built to close that gap.
This year marks our eighth. It is a moment to thank the people who made it possible, and to reflect honestly on how much the ground beneath this industry has shifted in that time.
How the threat picture changed
In 2018, the security conversation for a private estate or a superyacht was largely about perimeters, cameras, and people. Access control, guarding, and a monitored CCTV feed covered most of what a client needed. The threats were, for the most part, at ground level.
That is no longer the case. Consumer drones became capable and inexpensive at extraordinary speed, and with them came a category of risk that did not previously exist for private clients: surveillance from above, intrusion without a boundary crossed, and privacy compromised from a distance with no physical trespass at all. Underwater approaches, GPS and AIS spoofing, and cyber intrusion into onboard networks followed the same pattern: threats that were once the concern of navies and governments arrived at the doorstep of private owners and commercial operators.
The industry’s response has often been to sell another box. Our conclusion was different. If the threat now spans land, air, sea, and network simultaneously, then the defence has to be a single, intelligence-led system rather than a collection of unconnected products. That principle has shaped every decision Halo has made since.
From one idea to a full-spectrum capability
Halo was founded on more than 30 years of combined industry expertise, and the technical work began before the company itself. Laser defence development in 2016 was followed by temperature and fever detection systems in 2018. The first HDDS-PM, the Halo Drone Detection System with Pilot Mitigation, reached deployment in 2022, built around a principle we still hold to: never jam, never interfere with a client’s own systems, and locate the operator rather than simply the aircraft.
The years since have been the most productive in the company’s history. The HDDS-PM was unveiled at the Monaco Yacht Show 2025, where live testing saw dozens of drones attempt to breach the perimeter without a single success. The PPE Patrol Dog followed in November 2025, extending autonomous safety oversight into industrial and construction environments. HaloAware launched in January 2026 as a unified command platform bringing CCTV, thermal radar, sonar, anti-drone systems, UAVs, and tender tracking into one interface. In June 2026, the Halo Multi-Delivery System (HMDS) launched in partnership with Vast Integrations, taking autonomous aerial logistics into the superyacht sector and beyond.
Today Halo maintains a portfolio of 18 integrated solutions across land, air, and sea, supported by a 24/7 Security Operations Centre and a dedicated Cyber Operations Centre. Who hold operational capacity in more than 90 countries with rapid deployment teams available within two to six hours.
The people who built it
Technology is the visible part of this business. It is not the part that matters most.
Eight years of work has been carried out by engineers who commission systems at shipyards to the standards that clients like Feadship demand, and by teams who have travelled across the world and boarded a moving vessel off St Kitts inside 48 hours because a client needed them there. It has been sustained by partners who chose to build alongside us, and by clients who trusted us with assets, families, and reputations that could not be replaced.
To every client, partner, and colleague who has worked with Halo over these eight years: thank you. The trust placed in us is the only reason any of the above was possible, and it is not something we take lightly.
What comes next
An anniversary is a poor place to stop, and we do not intend to treat it as one.
The next phase of Halo’s work is focused on deeper integration and greater autonomy: systems that do not merely alert but assess, prioritise, and recommend; AI-driven robotic patrols that extend coverage without extending headcount; and continued development in electromagnetic and counter-UAS defence as aerial threats grow more capable. Our commitment remains to build on our own technology and to deliver it discreetly, because for the clients we serve, security that draws attention has already failed.
The threats will keep evolving. So will we.
