The challenge

Corporate meeting

Secure remote access for classified environments

25,000 civil servants requiring access to Official Sensitive applications from any location

Government Department operates under Official Sensitive classification requirements. Civil servants require access to legacy applications—many pre-Windows 10—that cannot run on modern operating systems. VPN-based remote access created complexity and friction.

Freedom of Information (FOI) disclosure risks meant every session must be logged, audited, and retrievable. The engagement required deploying Windows 365 Cloud PCs in GCC High compliance level, integrating legacy apps via app streaming, implementing certificate-based Multi-Factor Authentication (MFA), and automating session archival for audit compliance.

Our approach

Windows 365 GCC High Deployment with Legacy App Streaming and Compliance Automation

Teceze designed a Windows 365 Cloud PC deployment built to meet government-grade compliance from the ground up. Cloud PCs were provisioned at GCC High compliance level with UK data residency, ensuring data never leaves UK borders, and every connection is protected by conditional access policies requiring MFA and end-to-end session encryption.

From challenge to transformation, the solution included:

GCC High Cloud PC Deployment

Windows 365 Cloud PCs provisioned at GCC High compliance level with UK data residency, conditional access requiring MFA for all connections, and end-to-end session encryption.

Legacy App Streaming

App Streaming (MSIX) enabling legacy desktop applications to run without modernization, appearing native to the Cloud PC, with weekly app updates deployed centrally.

Certificate-Based MFA

Government PIK certificates as primary authentication, with automatic enrollment into certificate management and revocation capability for terminated staff.

Automated Session Recording

Automatic recording of every Cloud PC session, archived to secure storage meeting FOI retention requirements, with searchable logs and a compliance dashboard for audit purposes.

Governance and Reporting Cadence

Operational transparency and stakeholder alignment are critical to program success. A layered governance model keeps program health and costs visible:

Cadence Forum Focus
Daily Operations Stand-up Cloud PC availability, session failures, legacy app issues
Weekly Security Review Access control changes, MFA enforcement, threat detection
Monthly Compliance Call FOI audit readiness, data residency verification, session archival status

What the client says

“Government operations require absolute data protection and auditability. Cloud PC with GCC High compliance removed friction—civil servants can work from anywhere while we maintain perfect audit trails. Every session is recorded, every access is logged, and every regulation is satisfied. This is how secure remote access should work.”
