Guardian National Security delivers professional security guard services tailored to Chatsworth’s industrial and commercial landscape. We protect warehouses, manufacturing facilities, business parks, distribution centers, retail shops, and office buildings across Chatsworth. Whether your property sits along Devonshire Street, in one of Chatsworth’s industrial zones, or within residential neighborhoods, we design security coverage that fits your needs. Our services include standing guards for high-traffic locations, mobile patrol units for larger properties, or customized combinations that maximize protection while staying within budget.
We don’t just place guards at your Chatsworth location and disappear. Our licensed security professionals actively prevent theft, control property access, deter vandalism, and address the specific risks facing warehouses and commercial facilities. Equipment theft and break-ins become far less likely when our trained team maintains consistent patrols and visible security presence. Every guard we assign completes extensive background screening and receives ongoing training to handle Chatsworth’s unique security challenges effectively.
experience
Guardian National Security maintains strict hiring standards because Chatsworth properties deserve professional security, not just warm bodies in uniforms. We put every candidate through multiple management interviews, comprehensive drug testing (with ongoing random testing throughout their employment), exhaustive background investigations, and verification of personal references.
Candidates who pass these screenings then enter our mandatory training program before ever setting foot on a client’s property. Our training program is led by retired law enforcement officers who bring real-world experience protecting industrial facilities, commercial properties, and businesses throughout areas like Chatsworth.
This comprehensive training 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
Guardian National Security exceeds California’s Bureau of Security and Investigative Services requirements. We continue training and testing our guards both in our offices and in the field to ensure the security team protecting your Chatsworth property stays sharp and current.
