The procurement aims to engage a contractor capable of delivering comprehensive personnel security services, including background investigations, continuous vetting, incident monitoring, risk analysis, and adjudication support for Department of Defense personnel, all while adhering to established security guidelines. This initiative is crucial for maintaining national security and readiness, as it aligns with the authority granted by the Fiscal Year 2018 National Defense Authorization Act for security vetting. Interested businesses are encouraged to submit a detailed Capability Statement by April 25, 2025, to the primary contact, Deborah Hagan, at deborah.l.hagan.civ@mail.mil, as part of the market research process.
