Guardian Security Systems, the largest independently owned Washington State security company, got a little larger today by acquiring Mountlake Terrace-based Absolute Security, a strong and local independent security company. Family owned and in business since 2010, Absolute has grown to serve over 1600 residential and business customers in western Washington.


We are excited to welcome the employees and customers of Absolute Security into the Guardian Security family. Like Absolute, we have built our reputation on dedication to our customers and continue our commitment to having a strong local presence. This acquisition will strengthen our ability to deliver on that promise.

– Ainsley Close, President


Our long-term and knowledgeable clients know the difference between the excellent and caring service of a local family owned and operated alarm company. Because of this, we have searched long and hard for a company that can continue to service you in the manner that we feel you have come to expect. We have researched, found, and developed a smooth transition plan with another local, family owned and operated alarm company, that has the ability and desire to service our fantastic clients as we have.
