Tarzana has a lot going for it as a neighborhood, but the crime numbers tell a story that business owners and residents here know too well. Burglaries have been a persistent problem across the area, with small businesses along Ventura Boulevard getting hit repeatedly and residential break-ins remaining a weekly occurrence under the LAPD’s Topanga Division. Vehicle theft and smash-and-grabs are regular issues too, and the reality is that police resources are spread thin across the entire San Fernando Valley. If you own property or run a business in Tarzana, waiting for something to happen before thinking about security is a risk you probably cannot afford to take.
Guardian National Security provides Tarzana security guard services built around the way this neighborhood actually operates. Whether you need a standing guard at a medical office, mobile patrols for a residential community, or overnight coverage for a retail location that keeps getting targeted, we put the right people in place and hold them accountable. We are not here to sell you a generic package. We learn your property, understand your risks, and build a plan that works.

About Us
Highly Trained, Thoroughly Vetted Security Guards Serving Tarzana, CA
Guardian National Security has a screening process that is designed to filter out the people who treat security work like a temporary gig. Every candidate sits through multiple interviews with our management team, submits to a full drug screening program that includes random testing for as long as they work here, clears a detailed background investigation, and provides personal references that we actually call. The majority of applicants do not make it through, and we are fine with that.
The ones who do get placed into a training program run by retired law enforcement professionals who spent their careers working real security situations across the Valley and greater Los Angeles. They do not teach from a textbook. They prepare our guards to handle the types of problems Tarzana properties actually face, from late night break-in attempts at storefronts on Ventura Boulevard to access control at gated communities and medical buildings. Our Tarzana security guard services are staffed by people who passed every test we put in front of them and continue to be held to that standard every shift.
Our training program covers:
- Power to arrest
- Observe and report
- Terrorism and WMD awareness
- Communications
- Public relations
- Post order duties
- Patrols
- Batons
- Pepper Spray
- CPR and first aid
