Your Shield, Our Priority

Protecting Your Property with Trained Security Professionals

A security guard service puts trained, licensed officers on your property to watch, deter, and respond, so your people, property, and peace of mind stay protected 24/7. That is the whole job, and we have done it here since 1995. CAL Security Group covers unarmed security, mobile patrol, fire watch, event and crowd control, and 24/7 dispatch across Los Angeles, Orange County, San Bernardino, Ventura County, and the San Fernando Valley. From one overnight guard to a full multi-site patrol route, we build the coverage around your Southern California property, not the other way around.

Every officer is licensed by the Bureau of Security and Investigative Services (BSIS), background-checked, insured, and bonded. You get a visible guard on post, a fast response when something goes wrong, and a written shift report you can actually read the next morning. Supervisors check in with guards day and night, so no post runs on its own.

Vision

To be the security guard service Southern California owners call first, known for trained officers, reliable patrol, and honest reporting on every shift.

Mission

To put licensed guards on your property who protect people, respond fast, and document every shift in plain language, with no long-term contract required.
