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.”
EXPERT INSIGHTS
Common Questions
Cornerstone’s primary U.S. coverage includes New York City, Los Angeles, Chicago, Miami, Houston, and Atlanta. Additional markets can be supported through licensed regional partners depending on your itinerary, risk profile, and requirements.
Yes. Licensing requirements vary by state, so assignments are staffed with in-house personnel and regional partners licensed in the relevant jurisdiction for that engagement.
Cornerstone’s U.S. engagements are unarmed. Protection is built around planning, discretion, and risk mitigation rather than a visible armed presence.
Yes. Cross-border coordination is one of Cornerstone’s core strengths as a Canada-based firm. We plan continuous coverage for executives moving between Canada and the U.S., including airport transfers, secure transportation, and advance work on both sides of the border.
Every assignment begins with a consultation and risk assessment, followed by advance work, travel and route planning, and coordination with the client’s schedule. The plan is adjusted throughout the engagement as circumstances change.
Timing depends on the market, the complexity of the assignment, and licensing requirements in that jurisdiction. We prefer advance notice for thorough planning, but we maintain rapid-response capability for urgent needs and can typically begin mobilizing within 24–48 hours.
