Secure Defence Collaboration

DISX SECURE COLLABORATION

DISX Secure Collaboration is a managed, sovereign Microsoft 365 environment designed for all organisations operating within regulated, policy-constrained or high-assurance environments including defence, government and critical national infrastructure.

DISX establishes and operates a clearly defined collaboration boundary, governing identity, device posture, access policy and configuration change to support stable and predictable programme delivery.

Delivered by security-cleared personnel within a sovereign cloud environment, DISX Secure Collaboration enables regulated teams to communicate, share information and manage documentation within a controlled, defensible operating model and at the OFFICIAL-SENSITIVE classification.
