Corporate & Commercial Building Security
Corporate security is judged at the front desk and proven after hours. We staff headquarters, office towers, and business parks with Officers who look sharp, speak well, and still know exactly what to do when something goes wrong.
Corporate Security Built Around Your Building
Corporate campuses, Class A office towers, and suburban business parks share the same exposure: the building empties at 6 p.m. and becomes an easy target. Diligence Security builds programs that cover both halves of the day — a professional, business-appropriate presence during tenant hours, and hard, verifiable Patrol coverage once the parking structure goes quiet. We protect corporate properties in Seattle, Bellevue, Kirkland, Redmond, Tacoma, and across the King County Eastside.
Corporate Headquarters & Single-Tenant Offices
A corporate headquarters has a reputation attached to its front door. Our Officers work the reception position as part of your Team: badge verification, visitor logs, vendor escorts, conference-room access, and quiet enforcement of the policies your HR and facilities leaders have already written. Termination standbys, restricted-floor coverage, and executive-arrival support are handled without drama and documented the same shift.
Multi-Tenant Office Towers & Business Parks
In multi-tenant buildings, the Officer is the one person every tenant sees. That means uniform standards, clear radio discipline, and consistent answers at the desk. For business parks with detached buildings and shared lots, a marked vehicle running randomized laps is usually the highest-value dollar a property manager spends — it changes the calculation for anyone casing the garage.
What Property Managers Get
- Lobby, front-desk, and reception coverage with badge, visitor, and vendor verification
- Garage, stairwell, and loading-dock sweeps to deter vehicle prowls and loitering
- Opening and closing procedures, including lock, gate, and alarm confirmation
- Camera and alarm-panel monitoring from the desk, with escalation to law enforcement
- GPS-verified Patrol check-ins that prove each lap happened
- Written incident reports suitable for ownership, counsel, and insurers
Common Corporate Risks We Plan Around
- Vehicle prowls, catalytic converter theft, and package theft in tenant parking structures
- Tailgating through badge doors and propped stairwell or loading-dock doors
- After-hours trespass, encampment activity, and vandalism on unlit exteriors
- Escalating visitors, former employees, and domestic situations reaching the lobby
- Unescorted contractors and cleaning crews in restricted areas
Trained for the Tenant Conversation
Every Officer completes the Diligence Officer Integration Program, which goes beyond the state minimum on verbal de-escalation, report writing, and lawful authority. That matters most in corporate settings, where the right outcome is a calm exit rather than a confrontation in front of employees or Clients. Our Supervisors audit posts in person, so standards hold on the third month the way they did on the first.
How Corporate Programs Are Staffed
Most Clients start with a Mobile Patrol program on randomized routes, then add a dedicated On-site Security post at the lobby desk once tenants see the difference. Tenant meetings, shareholder functions, all-hands events, and holiday parties are covered by our Event Officers, and alarms, lockouts, and after-hours break-ins route to our 24/7 Emergency Services line. Buildings under renovation or with an impaired fire system are covered by certified Fire Watch Officers.

Commercial & Corporate Security Questions, Answered
- What does a corporate security Officer do day to day?
- A corporate Security Officer staffs the lobby or front desk, verifies employee badges and visitors, escorts vendors and terminated employees, monitors cameras and alarm panels, walks garages and stairwells, confirms locks at close, and files a written report for every shift.
- Do you provide unarmed corporate security Officers in Seattle and Bellevue?
- Yes. Diligence Security deploys uniformed, unarmed corporate Security Officers throughout Seattle, Bellevue, Redmond, Kirkland, Renton, Tacoma, and the wider Puget Sound region, for single-tenant headquarters as well as multi-tenant office towers.
- Can we start with after-hours coverage instead of a full-time post?
- Most corporate Clients begin with randomized Mobile Patrols between close and open, then add a fixed On-site post once tenants see the value. Coverage can be scaled by floor, by building, or by season without changing providers.
- How quickly can corporate coverage start?
- Standard corporate posts are typically staffed within a few business days after a walkthrough and post orders are approved. Emergency and short-notice coverage is handled through our 24/7 Emergency Services line.
- Do your Officers handle workplace terminations and restricted-access situations?
- Yes. Termination standbys, restraining-order enforcement support, and restricted-floor access are common assignments. Officers are trained in verbal de-escalation and documentation so the outcome is a calm exit and a defensible written record.
