AI Data Security Posture: Purview DSPM Implementation

Know What Your AI Can See - Before It Becomes a Risk

Microsoft 365 Copilot and AI tools are transforming how organisations work. But most organisations deploying AI have a critical blind spot: they have no visibility into what sensitive data their AI can access, summarise or surface - and no controls in place to stop it from exposing information it shouldn't. Overshared files, unclassified records, forgotten SharePoint content and over-permissioned users don't disappear when you switch on Copilot. They become AI-accessible overnight - creating data breach risk, regulatory exposure and compliance gaps that traditional security tools are not designed to catch. Codec's Secure AI Implementation: Purview DSPM for AI closes that gap. It is a fixed-scope, expert-led engagement that gets your organisation fully operational on Microsoft Purview's Data Security Posture Management for AI - giving your security, compliance and IT teams the visibility and controls they need to adopt AI safely and confidently.

What This Offer Delivers Phase 1 - Assess & Discover (Weeks 1–2) We begin with a full tenant and Microsoft 365 Copilot readiness review, establishing your AI data posture baseline. Using Purview DSPM for AI, we run a comprehensive sensitive data discovery scan across your Microsoft 365 estate - identifying unclassified, overshared and at-risk content that is currently accessible to AI tools. We produce a prioritised data risk map showing your highest-exposure assets by location, owner and AI accessibility.

Phase 2 - Classify & Protect (Weeks 3–5) We deploy sensitivity labels and auto-classification policies across Microsoft 365 and Copilot interactions, configure Data Loss Prevention policies for AI use cases, and establish Copilot guardrails and sensitive data exclusions. The Purview DSPM dashboard is configured to give your security and compliance teams live visibility into AI data activity, access patterns and risk scoring - turning a one-time assessment into an ongoing operational capability.

Phase 3 - Govern & Handover (Week 6) We configure AI usage governance reporting and establish a compliance audit trail - ready for regulatory review under GDPR, NIS2 or ISO 27001. Your security, compliance and IT teams receive targeted enablement sessions. Full operational runbooks and documentation are handed over, and Codec provides 30 days of post-go-live hypercare support.
