Serving the Greater Seattle Area
Security Company in Seattle, WA
ProTacOne deploys trained, professional security officers throughout Seattle and the surrounding King County region — protecting commercial properties, multifamily communities, construction sites, and events.
Professional Security Services Across Seattle
Seattle's density, diverse neighborhoods, and active commercial corridors create unique security challenges. From Capitol Hill retail corridors to South Lake Union tech campuses, from Sodo industrial facilities to Eastside multifamily communities, ProTacOne provides security solutions calibrated to the specific risks of each environment.
Our officers are trained, vetted, and Washington State licensed. We don't staff warm bodies — we deploy security professionals who understand de-escalation, emergency response, access control, and the legal boundaries of private security work.
ProTacOne is headquartered in Tacoma and serves clients throughout the Puget Sound region, including Seattle, Bellevue, Renton, Kent, Burien, and surrounding King County communities.
Seattle Security Services
From a single officer to a full security program, ProTacOne scales to fit your property and budget.
On-Site Security Officers
Uniformed security officers stationed at your property — deterring unauthorized access, monitoring activity, and responding to incidents. Available armed or unarmed based on your risk profile.
Mobile Patrol & Roving Security
Scheduled and random patrol routes covering multiple properties or large campuses. Mobile patrol is a cost-effective alternative to full-time on-site staffing for lower-risk properties.
Commercial Property Security
Retail centers, office buildings, warehouses, and mixed-use developments. We work with property managers and building owners to develop security programs that reduce liability and protect tenants.
Multifamily & Apartment Security
Residential communities face trespassing, package theft, parking violations, and after-hours disturbances. ProTacOne provides consistent, professional presence that keeps residents safe and management protected.
Construction Site Security
Equipment theft and vandalism are constant threats on active job sites. Our officers provide overnight and weekend coverage to protect your materials, machinery, and project timeline.
Event Security
Concerts, corporate events, private gatherings, and public functions. ProTacOne provides crowd management, access control, and incident response for events of any scale across the Seattle metro.
Alarm Response
When an alarm triggers, response time matters. ProTacOne provides rapid alarm response services — dispatching officers to assess, secure, and report on your property before police arrival.
Fire Watch
Required when fire suppression systems are offline or during high-risk construction phases. Our certified fire watch officers maintain continuous monitoring and documentation to keep you code-compliant.
Security Consulting
Not sure what level of security your property needs? Our consultants assess your vulnerabilities, review existing protocols, and deliver a practical security plan — without overselling services you don't need.
