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.

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.
