Security done properly.
Protection you can trust.
oSecurity Ltd delivers professional manned guarding, door supervision and mobile patrol services across London and the South East. Every officer is SIA-licensed, BS 7858 vetted, and held to standards that reflect the seriousness of the job.
A full spectrum of security services
Whether you need a single officer on the door or a full coverage plan across multiple sites, we deploy licensed professionals matched to your risk profile, environment, and expectations.
Manned Guarding
Static site officers providing visible presence, access control, patrols, and incident response. Uniformed, radio-equipped, trained to your site-specific assignment instructions.
Door Supervision
Licensed door supervisors for bars, clubs, restaurants and late-night venues. Skilled in conflict resolution, capacity management, and ID verification — calm presence, firm standards.
Event Security
Scalable event teams for conferences, private functions, sporting events and public gatherings. End-to-end: risk assessment, accreditation, crowd flow, medical liaison, close-down.
Key Holding & Alarm Response
24/7 key holding with rapid response to alarm activations. Fully vetted officers attend site, conduct full inspection, liaise with emergency services, and file a detailed report.
Mobile Patrol
Cost-effective marked-vehicle patrols at randomised intervals. Ideal where a full-time guard isn't viable but visible deterrence and periodic checks are essential.
Construction Site Security
Dedicated site security for construction, plant and material protection. Access control, plant register checks, perimeter patrols, and theft deterrence during live builds and shutdowns.
Standards that aren't optional.
The security industry is crowded. What separates us isn't a slogan — it's the things clients rarely get to see: our vetting processes, our documentation discipline, the calibre of the people on shift, and the fact that there is always someone contactable when it matters.
“We treat every assignment — a single-guard retail site or a full event deployment — with the same standard of professionalism. No exceptions.” — oSecurity Operations
