BSIS-LICENSED SECURITY GUARDS
Trusted By Thousands of Los Angeles Businesses
Our professional security guards are all completely licensed by the State of California’s Bureau of Security and Investigative Services (BSIS). Additionally, we provide ongoing, mandatory training in powers to arrest, CPR and first aid, observe and report, baton and pepper spray, terrorism and WMD awareness, patrol, communications, public relations, and emergency situations. We ensure that our guards are always on site and alert through the use of a state-of-the-art time clock system, and through regular, random visits by our management team. We also use Detex GPS equipment to record the exact movements of our guards and patrols throughout their watch.
