They may be armed or unarmed depending on the employer’s needs and local laws, but they always conduct themselves professionally—by escorting individuals back to their cars if necessary.

      Security guards protect people and property by investigating accidents and other emergencies, rescuing victims, and preventing crimes like vandalism or burglary. With crime rates on the rise and property damage costs continuing to climb, security companies may be tempted to reduce their service levels in a bid to provide clients with low-cost protection.

      Private security guards are an affordable option for people who want extra protection. While police officers are responsible for enforcing laws and maintaining order, private security guards focus on protecting individual people or businesses. Our security guards are trained to respond to a variety of situations, including personal and property protection. Our trained guards help people who are in danger or who have been injured, and they may also be called upon to assist police officers with crowd control or other situations that require additional manpower.

      Superior Training

      Our guards have superior training with a minimum of 40 hours of classroom learning and on the job training. Other more specialized guards have even more training than that. This training allows them to know what to do in emergency situations and gives them options that other less trained guards might not understand or be able to implement.

      We ensure that our guards always have the latest high tech equipment. This allows them to do their jobs more efficiently and allows them to be safer while protecting you and your property. We take pride in the equipment we equip our guards with as it allows them to be the best security guards in Los Angeles California.
