Zero Trust in 2026: Operationalizing Software Security for Federal and Defense Missions

Zero trust verifies who is asking for access, not whether the application behind it can be trusted. This Checkmarx white paper translates OMB M-22-09, EO 14144, and OMB M-26-05 into a four-phase roadmap for software-centered zero trust and a mandate-to-evidence table: the SBOMs, application security test results, and records to retain for ATO, cATO, and contractor oversight. Learn how to produce defensible software evidence without reconstructing release history for every authorization review.
