Armed Security

We utilize highly trained, and knowledgeable armed security guards who provide clients with safety and peace of mind. Our armed team members are licensed by the California Bureau of Security and Investigative Services (BSIS). This license verifies that they meet state regulations for providing security services and adhere to strict security protocols and legal regulations; requiring extensive training in firearm handling and emergency response procedures.

Unarmed Security

Our unarmed security guards are equipped with unique skills and knowledge to provide clients with safety and peace of mind. Our unarmed team members are also licensed by the California Bureau of Security and Investigative Services (BSIS). They utilize non-lethal deterrents with a primary focus on maintaining safety and deterring crime through vigilant observation, effecient decision-making skills and high visibility.

Private Patrol

Our private patrol security guards operate out of clean, well-maintained, and fully equipped patrol vehicles to provide dynamic protection. Private patrol can provide an added layer of security to any premises. Our private patrol team members actively patrol designated areas by vehicle (or by foot), monitoring for suspicious activity, enforcing property rules, controlling access to buildings, responding to emergencies, all while aiming to deter criminal activity and maintain safety.

Have peace of mind knowing that our dedicated team members are actively monitoring live video feeds from surveillance technology. Our team members ensure the proper functioning of surveillance systems and are trained and equipped to respond appropriately to security breaches and potential threats.
