The executives, officials, and senior leaders who operate here require personal security that is professional, unobtrusive, and built around how they actually work.

WHAT OUR CLIENTS SAY
★★★★★
“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 because the original company failed to provide required documents. They provided all the paperwork super fast at an affordable price. On the day, the security guards were very responsible and helpful. If you’re looking for a security company, Cornerstone is the best one. 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 for patrol. We have noticed a lot of improvement: no unwanted trespassers in our premises after hours and they responded to emergencies within 30 minutes. We are happy with our choice and highly recommend Cornerstone to anyone in need of security.”
