What is Defense Information System for Security (DISS)?

The Defense Information System for Security (DISS) is a web-based application managed by the Defense Counterintelligence and Security Agency (DCSA). It's the system of record for personnel security clearances, access, and visit requests within the Department of Defense and other federal agencies. DISS replaced the Joint Personnel Adjudication System (JPAS) and serves as a centralized platform for managing security clearance information, processing visit requests, and initiating personnel security investigations. It is commonly used by security managers, security professionals, and authorized personnel to verify clearance status, submit visit requests, manage personnel security data, and maintain compliance with security regulations.
