The Department of Defense (DoD) Chief Information Officer (CIO) Zero Trust Portfolio Management Office (ZT PfMO) has issued a Request for Information (RFI) seeking automated Zero Trust (ZT) Threat-Based Cyber Assessment (TBCA) solutions. This RFI is for market research purposes only and does not constitute a solicitation. The DoD aims to transition from manual, compliance-based cybersecurity assessments to continuous, automated, and threat-based approaches. The objective is to identify solutions that can emulate adversarial activities to assess ZT implementations on UNCLASSIFIED and SECRET networks, validate adherence to the DoD Zero Trust Strategy, reduce assessment time and costs, and support continuous TBCAs. The ZT PfMO is looking for solutions applicable across various environments (on-prem, cloud, hybrid) that can run within a Component's environment, be ready for production by Q2 FY26, and be procurable by DoD Components. Industry input is requested on strategies for onboarding, impact level access, threat frameworks, aid to cyber teams, replacement of manual assessments, existing government deployments, total cost of ownership, continuous analysis capabilities, assessment of Advanced level ZT activities, earliest deployment timeframe, and reporting capabilities. Responses, limited to ten pages, must be unclassified and submitted electronically by 12 PM ET on February 10, 2026.
