Crimson Security Service is a locally owned and operated security staffing firm headquartered in Smyrna, Tennessee, proudly serving clients throughout Middle Tennessee. We were founded on a simple observation: too many security firms in this industry fall short on the one thing clients value most — genuine, responsive customer service.
Our leadership team brings decades of combined experience in both the security industry and law enforcement, giving us a firsthand understanding of what it takes to protect people and property effectively. That experience shapes everything we do, from how we train our officers to how we manage every client relationship.
We built Crimson on the traditional values of honesty, integrity, hard work, and accountability. Unlike national security firms that treat clients as account numbers, we offer something different: local decision-making, flat-rate pricing you can count on, and a single point of accountability for every contract we manage. When you call Crimson, you're talking to the people who actually run your account — not a call center.
We provide armed and unarmed security officers, patrol services, event security, and specialized training programs to a wide range of industries across Rutherford, Davidson, Sumner, Wilson, and surrounding counties — including apartment communities, hotels, industrial and warehouse facilities, healthcare, construction sites, corporate campuses, and government properties.
At Crimson Security Service, we believe security is more than a service — it's a relationship built on trust, responsiveness, and results.
