At Guardian National Security, we go the extra mile to provide customer care that is accessible 24 hours a day, 7 days a week. Our goal is to create clear channels of communication between our clients, guards, and management team. We accomplish this through our Management Customer Service Program (MCSP), which provides clients with incident reports, daily activity reports, and random onsite visits to assess the performance of your assigned guards and ensure adherence to your contracted security services. We also monitor our guards using a GPS-enabled Detex app and electronic time clocks, and require our guards to check-in every 30 minutes. All our guards and management staff carry pagers, radios, and cell phones, and can be reached through our dispatch operators any time of the day or night.
