Microsoft Data Security & Governance

Microsoft Purview is Microsoft’s family of data security, governance and compliance solutions. It covers data classification and sensitivity labels, data loss prevention (DLP), insider risk management, retention and lifecycle management, eDiscovery and audit, plus data governance with the Purview Unified Catalog across Microsoft 365, Azure, Microsoft Fabric and other sources.

Copilot respects your existing permissions and sensitivity labels, so it can surface anything a user already has access to. Purview helps you find overshared content, apply labels and DLP policies so sensitive information isn’t exposed in Copilot responses, and gives visibility of how AI is being used across the organisation.

Microsoft Defender XDR is Microsoft’s extended detection and response suite. It correlates signals from endpoints, identities, email and collaboration tools and cloud apps into unified incidents, with automated investigation and response, so security teams can see and stop an attack across the whole environment from a single view.

Not necessarily. Many advanced Purview and Defender capabilities are included in Microsoft 365 E5 or its security and compliance add-ons, while E3 and Business Premium include a smaller set. We review your current licensing first, so you make full use of what you already pay for before considering any upgrade.

Security hardening means reviewing and tightening how your tenant is configured: identity and multi-factor authentication, conditional access in Microsoft Entra ID, admin roles, external sharing, email security, device policies and logging. Progress is measured against best practice and tools such as Microsoft Secure Score.

The GDPR requires you to know what personal data you hold, keep it secure, retain it no longer than necessary and respond to requests such as subject access requests. Microsoft Purview helps you discover and classify personal data, apply retention policies, prevent unauthorised sharing and search content efficiently. Tools support compliance. They don’t replace the right policies and processes, which we help you put in place.

Security should be monitored continuously, with a formal review at least once a year and after any major change, such as moving new workloads to Azure, an acquisition or rolling out Copilot. Configurations drift over time, so regular checks keep your protection aligned with how the business uses Microsoft 365 and Azure.
