Government Network Isolation and Classified Data Paths

Public sector organisations manage citizen data, classified information, and critical government services. Nation-state actors and criminal groups increasingly target government networks for espionage, disruption, and data theft.

"The ransomware encrypted 28 years of social services case files. We could not access safeguarding records for 4,000 vulnerable adults and children. For three weeks, social workers were operating blind on the highest-risk cases in the borough."

Physical governance for government networks.

Government organisations gain physical separation between citizen-facing services, sensitive data systems, and classified information zones. Ransomware cannot propagate from email to safeguarding records. Nation-state actors cannot traverse from public services to classified systems. Recovery from sophisticated attacks is guaranteed.

• Physical separation between government network zones
• Classification boundary enforcement for sensitive data
• Multi-party authorisation for citizen data access
• Independent management communications for incident response
• GovAssure and NCSC CAF compliance evidence
• Air-gapped recovery for rapid service restoration

UK Sovereign Infrastructure

All government data remains within the agreed UK jurisdiction in NATO-approved Firevault Bunkers, meeting Cabinet Office and NCSC data sovereignty requirements.

Role-Based Zone Access

Access to different government zones requires authorisation appropriate to the classification and sensitivity of the data within each zone.

GovAssure Compliance

Automated compliance logging maps directly to GovAssure, NCSC CAF, and Cyber Essentials Plus requirements for government organisations.

Independent Communications

Out-of-band management via dedicated communications ensures governance capability independent of the government network infrastructure.

Government Audit Trail

Every access to citizen data and government systems is recorded in tamper-proof logs meeting National Audit Office evidence requirements.

Rapid Service Recovery

Air-gapped copies of government systems enable rapid restoration of citizen-facing services during ransomware or state-sponsored attacks.

Government Network Assessment

Map all network paths between citizen services, sensitive data systems, corporate IT, and classified zones against GovAssure and NCSC CAF requirements.

Zone Architecture Design

Design physically separated zones aligned to data classification and service criticality with Control modules at each boundary.

Priority System Pilot

Deploy for the highest-risk systems first, typically safeguarding and social services data, with full zone separation and compliance logging.

Department-Wide Deployment

Phased deployment across all government systems with air-gapped recovery, continuous GovAssure evidence, and independent management communications.
