On-Site Security Officers
Professional On-Site Security Services by Diligence Security
On-site Security Officers provide continuous physical presence at a property to monitor activity, control access, and respond immediately to developing situations. Unlike patrol-based coverage, on-site Security places a trained Officer directly at the location to maintain consistent oversight throughout operating hours or overnight periods.
Diligence Security provides professional on-site Security services throughout Pierce County and King County, including Puyallup, Tacoma, and surrounding communities. Our Officers help deter criminal activity, support property operations, and provide reassurance to tenants, employees, and visitors through visible and professional presence.
What On-Site Security Officers Do
On-site Security Officers actively monitor property conditions and respond to issues as they occur. Responsibilities are tailored to each location but commonly include:
-
Monitoring entrances and controlling access points
-
Observing and reporting suspicious activity
-
Assisting tenants, staff, and visitors when needed
-
Performing interior and exterior patrol checks
-
Responding to alarms or disturbances
-
Documenting incidents with detailed reporting
Continuous presence allows faster response and consistent monitoring compared to periodic inspections alone.
When On-Site Security Is the Right Solution
On-site Security is typically recommended when properties require ongoing supervision or frequent interaction with occupants or visitors.
Common situations include:
-
High traffic commercial properties
-
Healthcare facilities and assisted living environments
-
Active construction projects
-
Residential communities requiring overnight monitoring
-
Locations experiencing recurring incidents
-
Properties needing controlled access or visitor management
​Many clients combine on-site Security during peak hours with mobile Security patrol services after hours to maintain cost efficiency while preserving coverage.
