I contacted Cornerstone Security after an outstanding recommendation from a colleague who had previously used their close protection services. Justice and Paul handled an unexpected ‘sensitive’ situation with tact and grace. This experience elevated my understanding of the security industry in Vancouver. Respectfully, this is not your average night watchperson patrol company, if you require a professionally-dressed elite team that you would expect in a large global city, Cornerstone is the licensed and fully insured option.


Since Cornerstone Security started working in our building, the service became impeccable!! Concierges are dressed very well, their work ethic is great and they always are nice to our dogs!

Cornerstone is really reliable and really professional. We hired them for a private university event the day before the event bc the original company failed to provide required documents. They were able to provide all the paper work super fast and provide us an affordable price cheaper than other companies. On the day of the event, the security guards are very responsible and helpful. If youre looking for a security company, Cornerstone is def the best one after contacting several other ones. 10/10 recommend

Managing a complex site comes with its challenges. Cornerstone Security has been by our side along the way with all hands on deck. They are knowledgeable, reliable, responsive and get the task done. Simply awesome and a pleasure to work with. Thank you Justice and team for all your hard work.

Great company, we hired them for our dealership and they have been conducting patrol. We have noticed a lot of improvement, no unwanted trespassers in our premises after hours and they have responded to emergencies within 30 minutes. We are happy with our choice of security and recommending them to anyone in need of security.
