California's Standard in Protection
For over a decade, Cal-Best Security has been the trusted choice for businesses, communities, and individuals who demand professional, reliable security across the state of California.
Built on Trust. Proven by Results.
Cal-Best Security was founded with a single mission: to raise the standard of private security in California. We saw an industry where clients were underserved, officers were undertrained, and accountability was an afterthought. We built Cal-Best to be different.
From our first contract protecting a small retail corridor in the Central Valley, we've grown into a statewide operation trusted by hundreds of businesses, HOAs, event organizers, and private clients. Every engagement — large or small — receives the same level of professionalism and care.
Today, Cal-Best Security is fully licensed by the California Bureau of Security and Investigative Services (BSIS), bonded, and insured. Our officers are background-checked, trained beyond state minimums, and held to a strict code of conduct that puts client safety first.

- ProfessionalismUniformed, trained, and held to the highest standards of conduct.
