Security Patrol Officers

Marked vehicles, randomized routes, and GPS-verified checks that make your property a hard target — without the cost of a full-time on-site post.

A predictable security routine is an invitation. Criminals watch for patterns — the same Officer parked in the same corner, the same lap at the same time each night. Our mobile patrol program is built to be unpredictable. Officers arrive on varied schedules, take randomized routes through your property, and physically inspect the vulnerable points that cameras miss.

What a Diligence Security patrol actually covers

Each visit is a working inspection, not a drive-by. Officers check door and gate integrity, verify lighting, document suspicious vehicles, clear loiterers, and confirm that after-hours access points are secure. Every action is logged with a GPS timestamp and, where relevant, a photo — so you receive verifiable proof of coverage rather than a signature on a paper sheet.

Who patrols serve best

Mobile patrol delivers the strongest return for properties that need a visible deterrent without a 24-hour post: retail centers, apartment and HOA communities, auto lots, business parks, and construction sites. Many clients pair patrols with a dedicated On-site Officer during peak hours and lean on 24/7 Emergency Response for after-hours alarm calls.

We run patrols throughout the region — from Pierce County to King County and beyond. Tell us your property's layout and risk history, and we'll design a route that closes the gaps.

Dependability is a core value at Diligence Security, and it is the value most tested by a Patrol contract. Every tour is verified, every log is auditable, and every route is designed so an Officer is on your property when you were told they would be.

Deployments Behind This Service

Non-profit Healthcare Network

Multi-site Healthcare Coverage That Lowered Use-of-Force Incidents

The Situation: A non-profit healthcare organization with five health centers and an administration building across Pierce County had inherited a security program from a previous provider that leaned on physical intervention. Staff were absorbing the stress of unpredictable encounters in patient areas, entryways, and parking structures.
Our Response: Diligence Security took over the program with a layered model: posted On-site Officers at the highest-traffic facilities, roaming Mobile Patrols connecting the remaining sites, and 24/7 emergency response for escalations after hours. Every Officer assigned to the account completes our Officer Integration Program, where verbal de-escalation and disciplined decision-making are trained well beyond the state minimum.
The Outcome: Use-of-force incidents dropped dramatically compared with the previous security company, and criminal activity on the properties was reduced. Just as importantly, the organization's employees report a markedly better sense of security while they work. This remains our longest-standing Client relationship.

“We have been very satisfied with Diligence Security's excellent service and rapid response. Their Officers are professional, provide a visible deterrent, and have been a proactive partner in improving communication, reporting, and security awareness across our locations.”
Letter of recommendation, Non-profit Healthcare partner — Pierce County, WA

Multifamily Apartment Community

Emergency Standby Coverage During a Serial Arson Threat

The Situation: An apartment community was targeted by an arsonist setting fires in rapid succession, leaving residents exposed and building systems compromised while ownership scrambled for contractors.
Our Response: Diligence Security deployed Officers on an emergency basis and held continuous coverage of the affected buildings — watching the vulnerable areas, documenting each round, and giving management and residents a visible presence during the highest-risk hours.
The Outcome: Coverage was sustained without interruption until the necessary repairs were completed and the property could stand on its own systems again. The deployment gave management a documented record of the response for its insurer and residents.
