Challenge
The Defense Intelligence Agency needed to modernize its network access controls across a geographically distributed classified environment. Legacy perimeter-based security models were insufficient to address insider threats and lateral movement risks in a multi-tenant, multi-classification environment.
The program required a Zero Trust architecture that would enforce least-privilege access, support continuous authentication, and integrate with existing identity management infrastructure — all without disrupting day-to-day mission operations.
Our Approach
CEdge assembled a cross-functional team of cybersecurity architects, network engineers, and IA specialists to design and deploy a phased Zero Trust implementation aligned with NIST SP 800-207.
Phase 1 — Discovery & Architecture Design We conducted a comprehensive asset inventory and network traffic analysis to map all data flows, user identities, and device types. This baseline informed a Zero Trust policy framework tailored to the agency’s classification boundaries.
Phase 2 — Identity & Device Trust CEdge deployed a unified identity platform integrating PIV/CAC authentication with continuous authorization policies. Device compliance checks were enforced at every access attempt using a combination of MDM integration and hardware attestation.
Phase 3 — Micro-Segmentation Legacy flat network segments were replaced with granular micro-perimeters organized around data sensitivity and mission function. Software-defined networking enabled policy enforcement at the workload level.
Phase 4 — Monitoring & Response A Security Operations Center (SOC) integration provided real-time visibility into access patterns. Automated anomaly detection alerted on deviations from behavioral baselines within minutes.
Results
- 94% reduction in unauthorized access incidents within 90 days of full deployment
- Full alignment with NIST SP 800-207 Zero Trust framework
- Zero mission disruptions during the 6-month phased rollout
- 47% reduction in mean time to detect (MTTD) for insider threat indicators
- Awarded follow-on task order for Zero Trust expansion to additional enclaves
