About Keystone

How we started
Keystone was founded with a basic premise - The best form of risk, is no risk at all.
We have focused on creating a small, specialised and experienced team and building consistent training and procedures across our business to ensure our customers receive the highest quality service in reducing and mitigating risk.
What we do
Keystone operate across Buckinghamshire, Bedfordshire and surrounding areas. We offer residential and commercial security solutions such as mobile patrols, risk assessment and event security.
All of our personel are experienced former blue light agents, with extensive experience in HM Prison Service and the Police.

Our Philosophy
Our philosophy is to be visible and accountable at all times. Our staff are all highly trained in areas such as risk reduction, conflict resolution and communication, meaning our security agents can assess and reduce risk, rather than reacting to it.
Our mobile app allows customers to view visit reports, risk assessments and patrol visits in real time, as well as tracking any issues that may be highlighted such as broken locks, signs of damage or disturbance and potential intrusion.
Where we work
Keystone offers residential security solutions and commercial security and risk management across Buckinghamshire, parts of Oxfordshire and Bedfordshire.
We are based in Buckingham, Bucks and Aylesbury, Bucks - allowing us to attend customers and schedule patrols across the county and beyond.
