The Department of Defense, through the Washington Headquarters Services, is seeking information on automated Zero Trust Threat-Based Cyber Assessment (TBCA) solutions as part of a Request for Information (RFI). The objective is to transition from manual, compliance-based cybersecurity assessments to continuous, automated, and threat-based approaches that can emulate adversarial activities to assess Zero Trust implementations on both UNCLASSIFIED and SECRET networks. This initiative is crucial for validating adherence to the DoD Zero Trust Strategy, reducing assessment time and costs, and supporting continuous TBCA across various environments, including on-premises, cloud, and hybrid setups. Interested parties are invited to submit unclassified responses, limited to ten pages, electronically by 12 PM ET on February 10, 2026, to Leanne Condren at leanne.m.condren.civ@mail.mil.
