Protecting Northern Virginia'sFinest Homes Since 1979
For nearly five decades, Dominion Security Systems has been the trusted name in home protection across Northern Virginia and the greater Washington DC region. What began as a father-and-son company has grown into one of the most respected independent security firms in the DMV — built on a foundation of integrity, personal accountability, and hands-on service that national chains simply cannot replicate. We are not a call center. We are not a franchise. We are your neighbors.
Our Story & Philosophy
When you call Dominion, you reach someone who knows your home.
Dominion Security was founded in 1979 on a straightforward belief: that protecting a family's home deserves more than a templated system and a 1-800 number. From day one, we have operated with a single standard — treat every client as if they are our only one.
Nearly 50 years later, that standard has not changed. Technology has evolved dramatically, and our systems reflect it — from advanced intrusion detection and monitored fire protection to smart home automation and whole-home audio. But through every evolution, the principles that defined this company on day one remain intact: precision installation, thoughtful consultation, and direct access to the people responsible for your system.
Our PhilosophyEvery home is different. Every family's needs are different. That is why we design every system from the ground up — built around how you live, not pulled from a catalog. We begin with a thorough consultation to understand not just your property, but your lifestyle. We account for how you use your space, what matters most to you, and how protection, automation, and integration can work together seamlessly and intuitively.
The result is a system engineered specifically for your home — one that enhances daily life while safeguarding everything within it. Precision matters. Personalization matters. And knowing our clients by name — not by account number — matters most.
