DISS serves as the enterprise-wide solution for personnel security, suitability, and credentialing management for DoD military, civilian, and contractors. DISS replaced the Joint Personnel Adjudication System (JPAS) as the System of Record on March 31, 2021. An innovative, web-based application, the platform provides secure communications between adjudicators, security officers, and components, allowing users to request, record, document, and identify personnel security actions. DISS will be an integral step toward the National Background Investigation Services (NBIS) platform currently in development and full implementation of the government-wide policy to overhaul the personnel vetting process known as Trusted Workforce 2.0.
