Government & Government Contractors
AD Security supports federal, state, and local agencies directly and partners with prime contractors as a specialized, cleared subcontractor for compliance, architecture, incident management, and our three specialist practices.
Federal experience
Our principal has led NIST 800-53 authorization programs for High, Moderate, and Low impact systems at NASA and GSA, designed the identity architecture for the GSA 2024 Presidential Transition, run incident management for a U.S. Army regional center, and directed statewide critical-infrastructure cyber oversight. Our full-time team includes senior associates with extensive ATO assessment experience and active Top Secret clearances.
For agencies: RMF and ATO support, 800-53 control assessment, Zero Trust roadmaps, PQC migration planning, AI risk assessments, and incident management.
For prime contractors: a senior, certified, cleared teaming partner who fills cyber SME roles, strengthens your technical approach with niche capabilities, and delivers on time.
For defense suppliers: CMMC and NIST 800-171 readiness from gap assessment through SSP, POA&M, and SPRS scoring, with mock assessments before your C3PAO engagement.
