Total Protection.
One Partner.
One Security Group is a new, Gloucestershire-based security provider delivering manned guarding, construction site security, specialist protection and electronic security systems — built around your site, your risk and your budget.
About One Security Group
A fresh start-up, built on established standards
We’re a new security partner launching in Gloucestershire — but our standards aren’t. Every officer we deploy is individually SIA licensed, every solution is designed around your specific site and risk profile, and every client works directly with people who know their business, not a call centre.
From manned guarding and construction sites to specialist protection and electronic security systems, we bring a single point of accountability to every contract — total protection, one partner.

SIA Licensed & Vetted

24/7/365 Availability
Security doesn’t keep office hours. Our teams and Control room are reachable around the clock, every day of the year.
Bespoke, Not Off-The-Shelf
We assess every site individually and build a risk-led plan — not a generic guarding package.
A Direct Relationship
As a new, focused provider you deal directly with the people managing your contract — not layers of account management.
