Yes, 1 Cerberus Security & Patrol is fully licensed (License: PPO 121682) by the California Bureau of Security and Investigative Services (BSIS) and carries comprehensive insurance coverage. Our guards are also individually licensed and trained to meet state and industry standards.
Armed security guards are equipped with firearms and are trained to handle high-risk situations where an elevated level of protection is required, such as banks or high-value asset protection. Unarmed security guards provide a visible deterrent and manage lower-risk environments, such as retail stores or office buildings, using non-lethal methods like de-escalation and surveillance.
Our guards undergo rigorous training, including state-mandated courses, specialized certifications (e.g., firearm training for armed guards), and ongoing education in areas like conflict resolution, emergency response, and customer service. We ensure they are prepared for any situation.
Our event security services cover a wide range of occasions, including corporate events, concerts, festivals, weddings, private parties, and more. We handle everything from crowd control and VIP protection to emergency response and coordination with local authorities.
