I’ve never felt safer than I have since I’ve hired Frontier’s Security Guards!

Frontier Security Guard & Patrol did a great job of discouraging homeless people from camping next to my Auto Repair Business. After multiple patrols, the homeless folks finally gave up and moved on. I would highly recommend their security service

Brian and his teams did a great job meeting our security needs. Friendly, responsive, effective professional security guards and night patrols. I look forward to continue working with Frontier through 2026.

Referred Frontier Security to a customer I have had for many years to do on site security in Denver earlier this year. My customer called me today to thank me for the referral, they have done an excellent job providing top notch security service, I really appreciate it, thanks guys!

We had a construction site in north Denver and were being plagued by theft and vandalism so we hired Frontier Security Guard & Patrol to provide overnight security services. Frontier was successful in deterring further vandalism and theft without incident. We'll be requesting their security services for future projects.
