SIA Licensed · London & Nationwide
Zentinel Security provides professional, fully-licensed security personnel across London. Corporate guarding, events, door supervision, mobile patrols, and more — tailored to your requirement.
What we provide
From static guarding to close protection, every service is delivered by trained, SIA-licensed personnel. We build solutions around your site, not the other way around.
Why Zentinel
Every client gets a dedicated point of contact, thorough site assessment, and personnel selected for your specific environment.
Every officer holds a valid SIA licence. We never deploy unlicensed personnel — no exceptions, no compromises.
Round-the-clock availability for emergencies, incidents, and urgent cover. One number, always answered.
No copy-paste contracts. We assess your site, understand your risks, and build a security plan that fits.
Our mission
Zentinel Security was built on the belief that peace of mind is priceless. We work with businesses, venues, and individuals across London who need security they can trust — not just a body on a door.
Our team holds accreditations with SafeContractor, NASDU, ISO, and the Achilles Network. We are fully registered with the ICO for data protection compliance.
