Why choose us?

From our London HQ we work with clients around the world to mitigate security risks and devise innovative solutions that harness technology, personnel and procedures for a holistic approach to Security.
We deliver outstanding solutions to world-class clients

At CornerStone, Customer Service is not a department, it’s embedded in everything we do. When your client list includes many of the worlds leading companies your standards have to be high. The on-going investment we make in our unique delivery process is all about providing excellence at every stage and ensuring outstanding results.

We save our clients money

Our clients choose to use an Independent Security Consultant for a number of reasons. It might be to perform a specialist task that they don’t have the in-house expertise or resources to deliver. It might be because they need the assurance of engaging a respected subject matter expert but what our clients all appreciate is our ability to save them money and deliver value wherever we can.

Independent Security Consultants

We are completely independent of any product manufacturer, system installer or other type of Security Company. We do not supply equipment, install products or provide commissioning services. Our solutions are based on your operational requirements - there’s no other agenda influencing our design or advice.

We reduce our client’s security risk profile

Before change can be implemented it is essential that the current position is understood and quantified. Improving our clients risk profile starts with a comprehensive analysis of their current situation. Only once we know what security threats they might be exposed to and what vulnerabilities exist can we define a risk rating and devise a plan of how to mitigate and where possible, eliminate security risks.

We protect our client’s property, people and profits

Looking after our client’s interests is in our DNA. As Independent Security Consultants we exist to help our clients protect their assets. We identify security risks, threats and vulnerabilities and then provide innovative ways to mitigate using a mixture of technology, personnel and procedures. The result is a holistic, joined-up response that improves our clients security posture.
