Your organisation most likely already owns Microsoft Purview. Most IT decision-makers don’t realise it, and that gap between what you own and what you’re actually using is where data risk quietly accumulates.
Microsoft Purview is Microsoft’s unified data governance and compliance platform, built into Microsoft 365. It covers data classification, information protection, data loss prevention (DLP), eDiscovery, insider risk management, and audit logging across Microsoft 365, Azure, and connected cloud services. Depending on your licence, some or all of this is already available to you right now.
The question most IT managers and CIOs should be asking is not what Microsoft Purview is. It’s whether your organisation is actually using what you’re already paying for, and whether the capabilities you’re missing are creating compliance or security gaps you haven’t yet quantified.
This guide covers what Microsoft Purview does, what it is used for, how licensing works, and whether your business needs additional investment or simply needs to activate what’s already sitting in your Microsoft 365 tenant.
Microsoft Purview: What It Is and Why It Matters
Microsoft Purview is not a single product. It is a suite of solutions that Microsoft consolidated under one brand in 2022, combining what was previously the Microsoft 365 Compliance Centre with the data governance capabilities of the former Azure Purview platform.
In practical terms, Microsoft Purview brings together two distinct but complementary capability sets. The first is compliance and information protection: sensitivity labels, DLP policies, eDiscovery, records management, communication compliance, insider risk management, and audit logging, all operating across Microsoft 365 apps and services. The second is microsoft purview data governance: data cataloguing, data mapping, lineage tracking, and automated classification across multi-cloud and on-premises data sources including Azure, AWS, and SQL environments.
Most Microsoft 365 customers already use some of this without realising it. Basic DLP policies and sensitivity labels are available from E3 upwards. The question is whether the capabilities included in your current licence are sufficient for your organisation’s risk profile and compliance obligations.
What Is Microsoft Purview Used For?
The answer to what is microsoft purview used for depends on your organisation’s size, sector, and data complexity. In practice, Microsoft Purview serves four primary functions:
- Data classification and sensitivity labelling: Automatically or manually classifying documents, emails, and Teams messages by sensitivity level, applying labels that control how information can be shared, copied, or stored across your Microsoft 365 environment.
- Data loss prevention (DLP): Enforcing policies that prevent sensitive information from leaving your organisation’s control, whether via email, Teams, USB drives, printing, or uploads to unapproved services. DLP operates at the app level and at the endpoint level with Microsoft Purview Endpoint DLP.
- Compliance, eDiscovery, and records management: Preserving, searching, and exporting content for legal holds, regulatory investigations, or internal audits across Exchange, SharePoint, Teams, and OneDrive. Relevant for organisations with FCA obligations, legal discovery requirements, or GDPR subject access requests.
- Microsoft purview data governance: For organisations managing data at scale across Azure, AWS, or hybrid environments, Purview’s data map and unified catalogue creates a searchable register of where data lives, how it is classified, and who can access it, which is increasingly essential as Copilot adoption grows across Microsoft 365.
Not Sure Which Microsoft Purview Capabilities You Already Have?
Transputec helps UK organisations understand what Microsoft Purview features are already active in their Microsoft 365 tenant, identify the compliance gaps, and build a data protection posture that fits their risk profile and budget.

Understanding Microsoft Purview licensing is where most organisations get confused, and where they either overspend or leave significant protection gaps. Here’s how it breaks down by Microsoft 365 plan.
Microsoft 365 Business Premium and E3 include core Microsoft Purview capabilities: manual sensitivity labels, basic DLP across Exchange and SharePoint, fundamental eDiscovery, basic audit logging, and foundational records management. These cover the basic compliance requirements for most smaller UK organisations and give you the framework to start classifying and protecting data.
What E3 does not include: auto-classification with machine learning, Endpoint DLP, advanced DLP policies across Teams messages and devices, Insider Risk Management, Communication Compliance, Advanced eDiscovery, or the full audit log retention that regulators typically expect. These capabilities require either Microsoft 365 E5 or the Microsoft Purview Suite add-on (formerly the E5 Compliance add-on, rebranded by Microsoft in 2026).
Microsoft 365 E5 includes the full Microsoft Purview premium suite alongside the Microsoft Defender security stack, Power BI Pro, and Azure AD P2. For organisations in regulated sectors, financial services, healthcare, and legal, E5 is typically the more commercially rational choice when you factor in the cost of purchasing the compliance capabilities separately on top of an E3 base.
As a Microsoft Azure and M365 partner, Transputec regularly conducts Microsoft 365 licensing reviews for UK organisations to identify where they are over-licenced or underprotected, and maps a cost-neutral or cost-reducing path to the right configuration.
Microsoft Purview Data Governance: Who Actually Needs It?
Microsoft Purview data governance, specifically the data map, unified catalogue, and lineage tracking capabilities, is a more advanced tier of Purview designed for organisations managing large, complex data estates across multiple cloud environments.
If your organisation’s data sits primarily within Microsoft 365, in SharePoint, Exchange, OneDrive, and Teams, then the compliance and information protection side of Microsoft Purview is what you need. The data governance side (cataloguing data across Azure SQL, AWS S3, Snowflake, on-premises databases, and so on) is designed for organisations with mature data platforms and dedicated data engineering or governance teams.
The clearest signal that you need microsoft purview data governance at this level is this: if your organisation cannot answer the question “where does our sensitive data actually live?” with any confidence, Purview’s data map and automated scanning capabilities provide that visibility. Microsoft’s data governance documentation outlines the scanning and classification process in detail.
For many UK SMEs and mid-market organisations, the more immediate priority is activating and tuning the compliance capabilities they already own but haven’t yet configured, rather than deploying the full data catalogue tier.
Do You Actually Need Microsoft Purview? Three Questions to Answer
Asking whether you “need” Microsoft Purview is, in most cases, the wrong question, because you likely already have it, or a substantial portion of it. The better questions are:
1. Are you using what’s already included in your licence?
Many organisations on Microsoft 365 E3 or E5 have Microsoft Purview capabilities sitting dormant in their tenant. No sensitivity labels have been defined, no DLP policies are active, and audit logs are running on the default short-term retention. If that describes your situation, the priority is not a procurement decision. It is a configuration and deployment one. This is a common finding when Transputec’s managed IT services team carries out Microsoft 365 health assessments for UK clients.
2. Do your compliance or regulatory obligations require capabilities beyond your current licence?
FCA-regulated firms, NHS suppliers, law firms handling privileged client data, and any organisation subject to UK GDPR with significant volumes of personal data should take a close look at what E5-level Microsoft Purview provides. Insider Risk Management alone, which detects unusual data access patterns and potential data exfiltration before they become incidents, is a significant control that regulators increasingly expect. The ICO’s UK GDPR guidance makes clear that organisations must implement appropriate technical measures to protect personal data.
3. Are you deploying or planning to deploy Microsoft Copilot?
This is the most pressing reason Microsoft Purview has moved up the priority list for many UK IT teams in 2026. Copilot accesses data through Microsoft Graph, meaning it can surface whatever the user can access. If your permissions are poorly governed, your sensitivity labels are absent, or your DLP policies are unconfigured, Copilot can expose sensitive information to users who shouldn’t see it. Getting your Microsoft Purview configuration right is a prerequisite for safe AI deployment across Microsoft 365.
Microsoft Purview and the Microsoft Compliance Centre: Understanding the Rebrand
One source of confusion when organisations research Microsoft Purview is the legacy terminology. The Microsoft Compliance Centre, Microsoft Information Protection (MIP), Azure Purview, and Microsoft 365 Compliance were all separate or differently named products before Microsoft consolidated them under the Purview brand in 2022.
If your IT team has previously worked with sensitivity labels, DLP policies, the Compliance portal, or Azure Purview data cataloguing, you have already been working with what is now called Microsoft Purview. The capabilities have not changed fundamentally. The brand has.
What has changed is Microsoft’s intent: the consolidation signals a move towards a single unified compliance and governance platform rather than a patchwork of separate portals and policies. For IT managers and CIOs, the practical benefit is that Microsoft Purview now provides a single administrative surface for data security and governance, reducing the complexity of managing compliance across a Microsoft 365 and Azure environment.
In 2026, Microsoft also rebranded the E5 Compliance add-on as the Purview Suite, available at approximately $12 per user per month on top of an E3 base. Organisations currently on E3 who need the full advanced compliance stack should evaluate whether the Purview Suite add-on or a move to E5 represents better commercial value for their specific situation.
Transputec’s Microsoft Modern Workplace team works with UK organisations to assess their current Microsoft 365 configuration, identify which Microsoft Purview capabilities are already licensed, what remains to be configured, and where additional licensing represents a commercially sound investment given their compliance obligations and risk exposure.
Conclusion
For the vast majority of UK organisations running on Microsoft 365, Microsoft Purview is not a question of whether to buy it. It’s a question of whether you’re using what you already own. Core sensitivity labels, DLP policies, and audit capabilities are available from E3 upwards. The advanced compliance stack comes with E5, and for regulated businesses, it is typically the primary reason the E5 premium is commercially justified.
The sharper question in 2026 is whether your Microsoft Purview configuration is keeping pace with the data risks your organisation actually faces, particularly as AI tools like Copilot move into production environments and create new requirements around data classification, access governance, and DLP policy coverage.
Transputec works with IT leaders across the UK to assess Microsoft 365 environments, identify compliance gaps, and put the right Microsoft Purview capabilities to work, whether that means activating existing licences or building a case for E5 investment.

FAQs
What is Microsoft Purview?
Microsoft Purview is Microsoft’s unified data governance and compliance platform, built into Microsoft 365. It covers sensitivity labels, data loss prevention (DLP), eDiscovery, insider risk management, audit logging, and, for organisations with complex data environments, data cataloguing and lineage tracking across multi-cloud sources. Depending on your Microsoft 365 licence, significant portions of Microsoft Purview are already included in what you’re paying for today. Visit Transputec’s Microsoft Modern Workplace page to find out what’s included in your current plan.
What is Microsoft Purview used for?
Microsoft Purview is used for classifying and labelling sensitive data, preventing data loss across email, Teams, SharePoint, and endpoints, managing compliance for regulatory obligations such as UK GDPR and FCA requirements, conducting eDiscovery for legal holds and investigations, and governing data across multi-cloud environments. In 2026, it has also become a prerequisite for organisations deploying Microsoft 365 Copilot, as Purview’s sensitivity labels and DLP policies control what data Copilot can surface to users. Transputec’s managed IT services team can assess which of these use cases apply to your specific environment.
Is Microsoft Purview included with Microsoft 365?
Yes, partially. Core Microsoft Purview capabilities, including manual sensitivity labels, basic DLP, fundamental eDiscovery, and basic audit logging, are included in Microsoft 365 E3. The full premium compliance suite, including auto-classification, Endpoint DLP, Insider Risk Management, Communication Compliance, and Advanced eDiscovery, requires Microsoft 365 E5 or the Microsoft Purview Suite add-on on top of an E3 base. Most organisations on E3 have access to more Microsoft Purview functionality than they are currently using. Transputec’s Microsoft M365 services team can carry out a licensing review to identify what’s available and what’s dormant in your tenant.
What is Microsoft Purview data governance?
Microsoft Purview data governance refers to the data cataloguing, data mapping, and lineage tracking capabilities within Purview, designed for organisations managing data across multiple cloud environments, including Azure, AWS, on-premises databases, and SaaS platforms. It allows organisations to discover where their data lives, automatically classify it, understand how it flows between systems, and assign data ownership. This is typically most relevant for mid-to-large organisations with mature data platforms and dedicated data teams. For most UK SMEs and mid-market businesses, the compliance and information protection side of Microsoft Purview is the more immediate priority.
How does Microsoft Purview help with UK GDPR compliance?
Microsoft Purview supports UK GDPR compliance in several ways. Sensitivity labels and DLP policies help prevent personal data from being shared inappropriately. eDiscovery capabilities support subject access requests (SARs) by allowing organisations to locate and export personal data quickly. Data retention policies enforce the UK GDPR principle of storage limitation. Audit logs provide the evidence trail regulators expect in the event of an investigation. The ICO requires organisations to implement appropriate technical measures to protect personal data, and Microsoft Purview provides the tooling to demonstrate those controls are in place. Transputec can help configure Microsoft Purview for your specific compliance requirements through our managed IT services.
