Our Comprehensive Security Guard Services
Armada Security has protected Bay Area businesses since 1994 — a California-licensed Private Patrol Operator (PPO 120526) with $1M per-occurrence and $5M aggregate liability coverage. Every officer is individually licensed and background-checked, works from a written post order, and files a daily activity report. Dispatch answers 24/7 — a real person, not a phone tree.
Providing Top-Quality Security Services for Businesses and Events in San Mateo
A security program is only as good as its accountability: written post orders, GPS-verified rounds, same-night incident reports, and a supervisor you can actually reach for businesses and events in San Mateo. With our top-quality security services, we are committed to protecting your assets and ensuring the safety of your employees, customers, and attendees.
Coordinated With San Mateo’s First Responders
San Mateo runs its own San Mateo Police Department — 116 sworn officers working out of 200 Franklin Parkway — alongside the San Mateo Consolidated Fire Department, a three-city agency that answered 15,823 incidents in 2024 with a 5½-minute average response to its highest-priority calls. SMPD’s Business Watch program shows how much the city leans on private eyes to extend a stretched patrol force. Our officers plug into that network: we coordinate with SMPD non-emergency dispatch, keep sites covered between patrol passes, and provide time-stamped, photo-logged incident reports that make police filings and insurance claims faster and cleaner.
