Serving Washington State For Over 40 Years.



From our Seattle-based Central Station, we serve one of the largest customer bases of locally monitored accounts, coordinating dispatch of police, fire, and medical emergency services for our customers.

Frank Close, CEO


No other security company can match Guardian's range of experience in integrated system design. And because we also install and service the systems we design, we understand the value of intelligent and farsighted planning. 



Our company employs over 170 residents in Washington State. We are committed to supporting our region. Locally owned and operated, we’re big enough to do the job, but small enough to care about the details of your system.
