Guardian Security Systems is the leader in residential and commercial life safety solutions. Established in 1976, Guardian specializes in comprehensive security, fire and life safety systems for installations ranging from single-family homes to major retail centers throughout Washington State. 

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. 

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 140 residents in Western Washington. 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.
