What Comprehensive Security Services does

Comprehensive Security Services, Inc. (CSSI) is a family-owned private security contractor founded in 1989 in Elk Grove, California, providing armed and unarmed guard services, vehicle patrol, firewatch, and AI-augmented mobile surveillance across California and Nevada, with state licensure also held in Louisiana, Massachusetts, and Puerto Rico. Core offerings are organized into a three-tier guard force — unarmed Security Officers, armed Protection Officers, and off-duty or retired Law Enforcement Officers — supplemented by a GPS-tracked marked patrol fleet (including hybrid Toyota Prius, Ford Maverick, and Ford Explorer 4x4 vehicles) and solar-powered AI surveillance trailers with active computer-vision detection, thermal imaging, and automated deterrent triggers. The business model is project- and contract-based professional services billing (long-term contracts plus month-to-month), with revenue drawn from federal/state/local government accounts (FEMA, DOT, USDA, U.S. Army Corps of Engineers, City of Sacramento, Sacramento County, Sacramento Unified School District, UC Davis), regulated utilities (PG&E), commercial and industrial properties, construction sites (including the 2024–2028 Folsom Dam Raise Project), high-rise buildings, home builders, and gated communities. Distribution is primarily direct enterprise field sales with a consultative assessment model, supported by inside-sales phone intake, a self-service website booking flow, government RFP bidding, and a referral network. Regulatory positioning — DBE, MBE, California Small Business, DIR, SAM UEI, CAGE Code — is actively leveraged as a competitive asset for diversity set-aside and prevailing-wage government work.
