What makes us different?

CornerStone are award winning, Independent Security Consultants.

We have developed a comprehensive range of services that are delivered through our unique security consultancy process which ensures high quality outcomes and happy clients. We are different from our competitors in many ways but here are six reasons why selecting CornerStone will always be a good decision.


We are the best at what we do. The CornerStone ethos is all about delivering the highest quality service we possibly can. Over recent years we have won numerous awards including winning the Security Consultants of the Year category at the Security Excellence Awards on a number of occasions. It is testament to our unique delivery process as well as a highly focussed and dedicated team that our clients experience a 5 Star service across all areas of our business, throughout every engagement.


Our independence is an essential part of our proposition. When you speak to us it is safe in the knowledge that you will receive unbiased, expert advice that is not influenced by a relationship with a particular manufacturer or installer. Our only goal is to deliver our clients objectives as comprehensively as we can.


We specialise in Security Consultancy, it’s all that we do. Under one of three business streams we can offer a broad based and joined-up approach to addressing even the most complex of requirements. Our dedicated team of security professionals are on hand and ready to support you wherever you are and on whatever you want – so long as it’s about security of course.


There are many aspects of security and there are many small companies that can deliver in one or two of these niche areas. There are very few organisations in the world who can offer expertise, experience and a delivery process that covers the full spectrum of security consultancy requirements. So whether it’s a system design, a security risk assessment, development of a new security strategy or any other area of security consultancy support, you can be certain that CornerStone will deliver a valuable contribution.

Client Focussed

Our unique delivery process is how we manage the quality of our service and retain our client focussed approach. We understand that without our clients we are nothing so we place our client relationships at the top of our agenda. Our team of Consultants have been carefully selected to ensure that this desire to delight our clients is embedded in everything we do.


Our clients recognise that above all we deliver value for their investment. That’s why 92% of our client engagements lead on to us providing additional services. It’s the value that we offer that our clients tend to appreciate and ensures that our ‘approval rating’ remains so high. Our ability to find creative solutions to some of the toughest challenges, work with stakeholder teams and understand the cultural context of key security decisions or offering advice and support whilst we’re delivering other projects, CornerStone understands the importance of delivering value to our clients.
