What DSI does

DSI Security Services is a family-owned, national contract security provider founded in 1969 and headquartered in Dothan, Alabama. Operating across 33 states with more than 5,500 employees, the company delivers integrated security programs organized into four divisions: Uniformed Security (armed and unarmed officers, mobile patrols, access control, receptionist services), Technology Solutions (remote video monitoring with machine learning-powered detection, mobile surveillance trailers, wireless access control via SALTO Systems, autonomous robotics, and the acquired Apex360 training and situational-awareness platform), Consulting (facility assessments, crisis management, violence prevention, workplace safety), and a National Security Operations Center (NSOC) for centralized 24/7 monitoring. The customer base spans commercial, industrial, manufacturing, healthcare, aviation, education, data center, entertainment, and HOA/residential segments, with named engagements including BMW (automotive manufacturing), Parkway Bank Park (entertainment district), Gulf Coast Jam (festival), and various food processing facilities.

The business model combines professional services (uniformed guarding and consulting billed via customized quotes and RFP processes) with managed/recurring services (NSOC and technology monitoring). Distribution is enterprise-direct through East and West division field sales organizations, led by regional VPs of Sales and Operations. Pricing is opaque and tailored to client scope. DSI holds private security licenses in 20+ states (Alabama, California, Florida, Illinois, New York, Texas, etc.) and is WBENC-certified as a women-owned business since 2011, currently the largest such employer in Alabama. The company has remained privately held under the Clark family throughout its 57-year history, with second-generation leadership (Marty Clark as Chairwoman, Alan Clark as Vice Chairman) and operational leadership transitioning to Deavours Clark (President) and Eddie Sorrells (CEO), the latter elected 71st President of ASIS International effective January 1, 2026.

Strategic activity has accelerated in 2024-2025: the company completed the acquisition of Chicago-based Apex3 Systems (August 15, 2025) to extend Midwest presence and absorb the Apex360 platform; launched nationwide Executive Protection services in partnership with Buckhorn Advisors (July 2025); introduced Mobile Surveillance Trailers and AI-enabled Remote Video Monitoring as new product lines; and reorganized executive leadership in April 2025. The product portfolio is unified under the "DWYSYWD" service philosophy, combining human security officers with technology-driven solutions to provide scalable protection for complex commercial and industrial clients.
