Black Diamond Security

What Black Diamond Security does

Black Diamond Security Services Ltd is a UK private security company founded in 2010 and headquartered in Armthorpe, Doncaster, operating as a subsidiary of the Black Diamond Group. It provides integrated manned guarding and proprietary technology-led security solutions to enterprise and public-sector clients across the United Kingdom, with regional offices in London, Birmingham, Bristol, Glasgow, Doncaster and Manchester.

Its core offering combines three layers. First, manned services include SIA-licensed static and mobile guarding, canine patrols, close protection and corporate surveillance, with security officers trained sector-specifically and recruited with a military-veteran emphasis. Second, the company designs, builds and maintains its own hardware — Rapid Deployment Cameras (RDC), the Security Eye detection unit, Solar Cameras, the RSI System and a Live Feed Video Analytic System — all monitored through an in-house 24/7 National Control Centre (NCC) running the IMMIX platform, which integrates with more than 500 third-party video, audio, alarm and GPS systems. Third, it delivers professional security services such as cyber and physical penetration testing, due diligence, executive digital profiling, risk advisory, and technical surveillance counter measures.

Revenue is generated through subscription-recurring manned guarding and 24/7 monitoring contracts, hardware sales of CCTV, intruder alarms, access control and fire protection systems, and project-based professional services. The go-to-market is direct enterprise field sales with dedicated regional account managers, targeting verticals in which it holds accreditations — rail (Network Rail, LNER, Hitachi, Vinci, Trans Pennine, GB Rail Freight, Sersa, SPL Powerlines), construction and utilities, corporate security, residential, retail and public sector — with a single-contractor partnership model that bundles hardware, monitoring and guarding into one contract.
