California is the largest private security market in the country. Security companies and their officers are licensed by the Bureau of Security and Investigative Services (BSIS): companies hold a Private Patrol Operator (PPO) license and officers a guard card. Demand spans corporate campuses in the Bay Area, entertainment and logistics in Greater Los Angeles, the Inland Empire's warehouse corridor, and agriculture and energy in the Central Valley.
