Our Company Values
Serving Washington State For 50 Years.


Technical Excellence

We love being great at what we do! Our team, from technicians, and sales engineers, to customer care representatives and project accountants, takes pride in our work. Our technical excellence comes from our tenured staff, ongoing trainings, diverse project experience, and strong product knowledge.

Frank Close, CEO

Customer Heroes

We provide life safety solutions and service our customers when they need us the most. We love to be the hero and solve customers’ problems both out in the field, from our desks, and with our internal customers, our own employees.


Predictable Success

We consistently deliver results for our customers by hitting targets day by day, week by week, month by month. We do our job every day and to do this we rely on all our team members. Employees own their role and predictably execute every day.



We practice kindness with our co-workers and with our customers. We believe that kindness in business is a virtue and not a vice–we believe in the lifetime value of our customers and our employees. Being clear and truthful with people is kind, being unclear is unkind.


Growth Mindset

We are not complacent. We want to ask tough questions. We continue to learn, are humble in interactions, and seek constant improvement.



Not only do we provide safety to our customers, but we practice it daily ourselves. If something is unsafe we stop it until it is safe again and report it.

Enterprise Systems Integration Solutions

Because we're skilled in all types of life and property protection systems, we can design integrated systems that combine your intrusion detection system with fire alarm systems, video security and access control systems in a single command and control center. Our integrated systems provide a greater degree of protection and alarm verification.

Only approved users (employees, trusted vendors, etc.) can scan their official credentials at a digital access device attached to the entryway – and you can rest assured that only authorized occupants are in the building.
Whether your needs are for a one or two camera installation or whether you require several hundred cameras, we have a solution for you. From a single color camera, to a camera with pan/tilt/zoom capacity, we can meet your needs.
When a camera is triggered, a Guardian monitoring professional will immediately check the video and call you to confirm an intrusion. If an unwanted intrusion is verified, Guardian will quickly call the police to report a robbery in progress.

Guardian Security can be your single-source provider for multiple fire and life safety solutions that can be integrated and networked for granularity of information.

The men arrived on time, were conscious of our request to test the alarms later so that our residents would not be frightened. They worked the better part of the day, not even stopping for lunch. They were polite and very professional. I was very impressed."

bug_logo-sm  "Our company underwent a state survey, and as a result we were required to have additional testing on our smoke alarms and zoned fire alarm system. The survey requirements needed to be met per state code as well as on a specific, quick, timeline. Guardian Security was extremely responsive. I made contact with Guardian, and was moved quickly and efficiently to the appropriate persons. Testing was completed in our office setting, during business hours, without hassle or disruption to our business. Everyone from reception, to scheduling, and the service technicians who performed the testing were exceptionally helpful. Very professional service, top to bottom!"

"There are many fire safety companies in the Seattle/King County area. Some who charge a bit less than Guardian Security. For the last thirty years, I have chosen Guardian Security to service and repair our buildings because of their knowledge and quality. Their advance notice of upcoming renewals takes scheduling off my busy "To Do" list and gives me plenty of time to alert the residents of the upcoming service. Their capability of quickly attending to an emergency is most comforting. I cannot imagine managing this aspect of our buildings without Guardian Security."
