Military, Defence & Government Security
Mission-grade cybersecurity for defence contractors, federal agencies, and public sector organisations. CMMC readiness, GCC High tenant hardening, Microsoft sovereign cloud, Adam Networks source-verified networking, and nation-state defence aligned to ITAR, FedRAMP, NIST SP 800-171, and ITSG-33.
Operating Context & Regulatory Pressures
Regulatory Landscape
- CMMC 2.0 (L1–L3) – Cybersecurity Maturity Model Certification 2.0 across Levels 1, 2, and 3 for the Defence Industrial Base
- NIST SP 800-171 / 800-53 – NIST SP 800-171 controls for Controlled Unclassified Information and SP 800-53 baselines for federal systems
- ITAR / EAR – International Traffic in Arms Regulations and Export Administration Regulations for defence articles and technology
- FedRAMP / IL4–IL5 – FedRAMP authorisation and DoD Impact Levels IL4 and IL5 for cloud services handling federal and defence workloads
- ITSG-33 / Protected B – Government of Canada ITSG-33 control profiles for Protected B and Secret-level systems
Industry Pressures
- Nation-state actors actively targeting the defence industrial base, federal agencies, and government contractors
- CMMC 2.0 enforcement now blocking DoD contract awards and renewals for non-compliant primes and subcontractors
- CUI and ITAR data routinely mishandled in commercial Microsoft 365 tenants instead of GCC High or sovereign environments
- Generative AI and agentic workloads expanding the threat surface across cleared workforces and mission systems
Common Failure Modes
CMMC Level 2 Assessment Failure
A defence prime contractor failed its C3PAO assessment when 38 of 110 NIST SP 800-171 controls were scored as Not Met. The shortfall blocked an $80M contract renewal and triggered a 12-month remediation programme under DoD oversight, with daily liquidated damages.
Root cause: No System Security Plan, missing POA&Ms, CUI processed in commercial M365, no continuous monitoring, evidence not aligned to assessment objectives
Nation-State Intrusion via Contractor Endpoint
An advanced persistent threat group compromised an unmanaged engineering laptop belonging to a tier-2 subcontractor, then pivoted into the prime's GCC environment and exfiltrated weapons system technical data over an 11-month dwell period before detection.
Root cause: No zero-trust segmentation between contractor and prime, missing EDR on subcontractor devices, DNS exfiltration unblocked, no source-verified networking enforced
ITAR Data Spillage in Collaboration Tools
Engineering teams shared ITAR-controlled drawings via a commercial Teams tenant accessible to foreign nationals on the licence. The State Department investigation resulted in a $3.2M civil penalty, mandatory consent agreement, and three-year compliance monitor.
Root cause: No tenant separation for ITAR workloads, missing information barriers, no data classification, no citizenship-aware conditional access, no GCC High migration

Case Example: Defence Industrial Base Prime Contractor
A defence prime supporting multiple DoD programmes engaged CriticalMatrix to recover from a failed CMMC pre-assessment, migrate ITAR workloads off commercial Microsoft 365, and harden against nation-state intrusion. Within 180 days we delivered:
- Full Microsoft 365 GCC High tenant build with Defender, Sentinel, Purview, and Entra ID Government configured to DoD baselines
- CMMC Level 2 readiness with System Security Plan, POA&Ms, SPRS scoring, and evidence library mapped to all 110 controls
- Adam Networks source-verified networking deployed across primes, subcontractors, and OT segments — blocking known nation-state C2 and DNS exfiltration
- Privileged access workstations, citizenship-aware conditional access, and Semperis-protected directory recovery for both Entra ID Government and on-prem AD
