Supporting the Nation’s Emergency Services Sector with Proven Security Solutions
The Emergency Services Sector (ESS) is essential to the safety and resilience of our communities. As the Sector-Specific Agency, the Department of Homeland Security oversees this critical infrastructure, which includes millions of highly trained personnel and the facilities, systems, and resources that support prevention, preparedness, response, and recovery efforts—both in daily operations and during times of crisis.
Advanced Professional Security (APS) is proud to play an active role in this vital sector. With a proven track record of providing reliable, responsive, and professional security services, APS supports both public and private emergency service organizations across a wide range of environments. Our team is trained to work alongside first responders and emergency personnel, offering security solutions that enhance safety, coordination, and operational continuity.

-
City police and fire departments
-
County sheriff’s offices
-
Department of Defense emergency services

Municipal public works and emergency management teams
