The Department of Defense (DoD) Chief Information Officer (CIO) is issuing a Request for Information (RFI) for market research purposes to explore how Artificial Intelligence (AI) and Machine Learning (ML) can enhance and automate Zero Trust (ZT) assessments across the DoD enterprise. The ZT Portfolio Management Office (ZT PfMO) seeks industry insights on Commercial Off-the-Shelf platforms and services that leverage these technologies to scale ZT Purple Team evaluations on UNCLASSIFIED and SECRET networks. The objective is to accelerate assessments, validate compliance with 91 Target Level Zero Trust Activities and ten Acceptance Criteria (detailed in Appendix A), identify limitations, and achieve Target Level ZT by FY27. The RFI poses 13 questions covering the use of automation and AI in ZT Purple Team activities, obstacles, suitable tasks, attack path identification, simulation of attack scenarios, analysis of detection effectiveness, report generation, valuable data sources, emerging trends, innovative technologies, barriers to entry, implementation friction points, and neural network training data. Responses are limited to ten pages, due by 12 PM ET on Feb. 9, 2026, and must be submitted electronically.
