GDPR Compliance in Power BI: Data Privacy and Residency Guide

<h2>Why GDPR Compliance in Power BI Is Non-Negotiable for European Operations</h2>

<p>The General Data Protection Regulation (GDPR) imposes strict requirements on how organizations collect, store, process, and transfer personal data of EU/EEA residents. Power BI, as a cloud-based analytics platform that ingests, models, and visualizes data—frequently including personal data such as employee records, customer transactions, patient information, and citizen service interactions—falls squarely within GDPR's scope. Non-compliance carries fines of up to 4% of global annual revenue or EUR 20 million, whichever is greater. Beyond fines, GDPR violations damage enterprise reputation, erode customer trust, and can trigger individual lawsuits from affected data subjects.</p>

<p>This guide provides a comprehensive, actionable framework for achieving and maintaining GDPR compliance across your Power BI deployment. It covers the technical controls, governance processes, and architectural decisions required to satisfy GDPR's core principles: lawfulness, purpose limitation, data minimization, accuracy, storage limitation, integrity and confidentiality, and accountability. Our <a href="/services/power-bi-consulting">Power BI consulting</a> and <a href="/services/data-governance">data governance</a> teams implement these frameworks for enterprises across healthcare, financial services, and government sectors where compliance failures carry the highest consequences.</p>

<h2>Data Residency: Multi-Geo in Power BI Premium</h2>

<p>Data residency—controlling the geographic location where data is stored at rest—is one of GDPR's most frequently cited requirements, particularly for organizations operating across EU member states, the UK post-Brexit, and countries with national data localization laws (Germany, France, Russia, China, India).</p>

<h3>How Power BI Stores Data</h3>

<p>By default, Power BI stores all tenant data (semantic models, reports, dashboards, dataflows) in the Azure region associated with the tenant's home country at the time of Microsoft 365 tenant creation. For a tenant created with a German billing address, data is stored in the EU (typically West Europe or North Europe Azure regions). For a US-based tenant, data resides in US regions.</p>

<p>The challenge arises for multinational organizations: a US-headquartered company with EU employees and customers needs EU personal data to remain in EU data centers, while US operational data stays in the US. Without Multi-Geo, all Power BI data is stored in the tenant's home region regardless of data origin.</p>

<h3>Multi-Geo Configuration</h3>

<p>Multi-Geo is a Power BI Premium feature that allows assigning specific workspaces to specific Azure regions. Configuration steps:</p>

<ol> <li><strong>Enable Multi-Geo</strong>: In Power BI Admin Portal, navigate to Tenant Settings, then Workload Settings, and enable Multi-Geo support. Requires Power BI Premium Per Capacity (P1+) or Fabric capacity (F64+).</li> <li><strong>Assign workspace region</strong>: When creating or editing a Premium workspace, select the desired Azure region from the "Storage region" dropdown. Options include specific EU regions (West Europe - Netherlands, North Europe - Ireland, France Central, Germany West Central, Switzerland North) and many others.</li> <li><strong>Data at rest guarantee</strong>: With Multi-Geo, the following data stays in the assigned region: imported data in semantic models, cached query results, dataflow data, semantic model metadata. Report and dashboard definitions (the visual layout, not the data) may be stored in the home region.</li> <li><strong>Verify data residency</strong>: Use the <code>Get-PowerBIWorkspace</code> PowerShell cmdlet with the <code>-Scope Organization</code> parameter to audit workspace region assignments across the tenant.</li> </ol>

<h3>EU Data Boundary</h3>

<p>Microsoft's <strong>EU Data Boundary</strong> commitment (phased rollout 2023–2025) provides an additional layer: for EU/EFTA-based tenants, all customer data processing—not just storage—occurs within EU data centers. This addresses GDPR concerns about data being processed (even temporarily) in US data centers. The EU Data Boundary covers Power BI along with other Microsoft 365 and Azure services. For organizations where EU data residency is a strict regulatory requirement, combining Multi-Geo workspace assignments with the EU Data Boundary provides defense-in-depth data residency controls.</p>

<h2>Right to Be Forgotten: Implementation in Power BI</h2>

<p>Article 17 of GDPR grants data subjects the right to request erasure of their personal data. Implementing this in a Power BI environment requires a systematic approach because Power BI is a downstream consumer of data—personal data typically originates in source systems (CRM, ERP, HRIS, clinical systems) and flows into Power BI through ETL pipelines.</p>

<h3>Erasure Architecture</h3>

<ol> <li><strong>DSAR intake</strong>: Establish a process for receiving and validating data subject access/erasure requests. Microsoft provides the <strong>DSAR tool in the Microsoft 365 compliance center</strong> for managing requests across Microsoft services.</li> <li><strong>Source system erasure</strong>: Delete or anonymize the data subject's personal data in all source systems (CRM, ERP, databases). This is the primary erasure action—Power BI mirrors source data.</li> <li><strong>Trigger Power BI refresh</strong>: After source system erasure, trigger a dataset refresh in Power BI. Import mode datasets will re-import data without the erased records. DirectQuery datasets will immediately reflect source changes on the next query.</li> <li><strong>Verify erasure in Power BI</strong>: After refresh, verify that the data subject's records no longer appear in Power BI reports. Check all semantic models that may contain the individual's data.</li> <li><strong>Handle cached data</strong>: Power BI caches query results (dashboard tiles, Q&amp;A results, query caching). These caches refresh automatically over time but can be forced by triggering a tile refresh or clearing the cache via the Power BI REST API.</li> <li><strong>Exported reports and screenshots</strong>: Data exported from Power BI (PDFs, Excel exports, screenshots, email subscriptions) cannot be automatically erased. Your DSAR process must include a manual step to identify and delete any exported copies.</li> <li><strong>Document the erasure</strong>: Record the DSAR, actions taken in each system, refresh timestamps, and verification results. Retain documentation for 3 years as evidence of GDPR compliance.</li> </ol>

<h3>Anonymization vs. Deletion</h3>

<p>GDPR allows anonymization as an alternative to deletion when the data is needed for statistical purposes. In Power BI, this means replacing personal identifiers with anonymous tokens in the source system, then refreshing the Power BI model. The analytical value of the data is preserved (aggregated trends, statistical patterns) while the individual is no longer identifiable. Implement anonymization at the ETL layer, not in Power BI itself—Power BI should receive already-anonymized data.</p>

<h2>Data Minimization in Power BI Semantic Models</h2>

<p>GDPR's data minimization principle requires that you process only the personal data that is strictly necessary for the specified purpose. In Power BI, this means:</p>

<ul> <li><strong>Exclude unnecessary PII columns</strong>: If your analytics do not require individual names, email addresses, social security numbers, or other direct identifiers, exclude them from the semantic model entirely. Query the source for only the columns needed for analysis.</li> <li><strong>Aggregate at the source</strong>: If report consumers only need department-level headcount, do not import individual employee records. Aggregate in the <a href="/blog/modern-data-lakehouse-fabric">ETL pipeline</a> or source view and import only the aggregation.</li> <li><strong>Use surrogate keys</strong>: Replace natural keys (email addresses, social security numbers) with surrogate integers in the semantic model. If a report needs to show individual-level data for authorized users, use <a href="/blog/power-bi-row-level-security">Row-Level Security (RLS)</a> to restrict access.</li> <li><strong>Separate PII from analytics</strong>: Design a <a href="/blog/power-bi-star-schema">star schema</a> where dimension tables containing PII are separate from fact tables containing metrics. Apply stricter access controls to PII dimensions than to metric facts.</li> <li><strong>Regular PII audits</strong>: Quarterly, review all semantic models for unnecessary personal data. Use Microsoft Purview's data classification scanning to automatically detect PII columns in Power BI datasets.</li> </ul>

<h2>Sensitivity Labels in Power BI</h2>

<p>Sensitivity labels from Microsoft Information Protection (MIP) extend to Power BI, enabling consistent classification and protection of analytics assets alongside Office documents, emails, and files.</p>

<h3>How Sensitivity Labels Work in Power BI</h3>

<ul> <li><strong>Label assignment</strong>: Apply sensitivity labels (e.g., "Public," "Internal," "Confidential," "Highly Confidential") to Power BI semantic models, reports, dashboards, and dataflows. Labels can be applied manually by content owners or automatically by policy.</li> <li><strong>Label inheritance</strong>: When a report is built on a labeled semantic model, the report inherits the model's sensitivity label automatically. This ensures downstream artifacts carry the source classification.</li> <li><strong>Export protection</strong>: When a user exports data from a labeled Power BI report to Excel, PDF, or PowerPoint, the sensitivity label travels with the export. An Excel file exported from a "Confidential" Power BI report is automatically labeled "Confidential" in Excel, with the associated MIP protections (encryption, access restrictions) applied.</li> <li><strong>Visual indicator</strong>: Sensitivity labels display as a banner at the top of reports and dashboards, making the classification visible to all viewers. This supports GDPR's accountability principle by making data classification transparent.</li> </ul>

<h3>Configuring Sensitivity Labels for GDPR</h3>

<table> <thead><tr><th>Label</th><th>Description</th><th>Power BI Protection</th><th>GDPR Relevance</th></tr></thead> <tbody> <tr><td>Public</td><td>No personal data, publicly shareable</td><td>No restrictions</td><td>Outside GDPR scope (no personal data)</td></tr> <tr><td>Internal</td><td>Business data without PII</td><td>Org-only sharing</td><td>Minimal GDPR impact</td></tr> <tr><td>Confidential</td><td>Contains personal data (names, emails, IDs)</td><td>Restricted sharing, export encryption, audit logging</td><td>GDPR personal data—requires legal basis, minimization, security controls</td></tr> <tr><td>Highly Confidential</td><td>Special category data (health, financial, biometric)</td><td>No external sharing, encrypted exports, mandatory justification</td><td>GDPR Art. 9 special category—requires explicit consent or specific legal basis</td></tr> </tbody> </table>

<h3>Mandatory Labeling Policy</h3>

<p>Enable <strong>mandatory labeling</strong> in Power BI Admin Settings to require all published semantic models and reports to have a sensitivity label. This prevents unclassified data assets from being shared without going through the classification process. Combined with <strong>default labeling</strong> (automatically applying "Internal" to new assets), this ensures 100% label coverage across your Power BI tenant.</p>

<h2>Data Loss Prevention (DLP) Policies for Power BI</h2>

<p>DLP policies detect and prevent the sharing of sensitive data in Power BI. Configured in the Microsoft Purview compliance portal, DLP policies for Power BI can:</p>

<ul> <li><strong>Detect sensitive information types</strong>: Automatically scan Power BI semantic models for credit card numbers, social security numbers, passport numbers, health record identifiers, and 200+ other built-in sensitive information types. You can also define custom sensitive information types matching your organization's data patterns.</li> <li><strong>Policy tips</strong>: Display a warning banner on Power BI datasets that contain detected sensitive information, alerting content owners that the data requires GDPR-appropriate handling.</li> <li><strong>Block sharing</strong>: Prevent sharing of datasets containing certain sensitive information types with external users or specific user groups that should not access PII.</li> <li><strong>Admin alerts</strong>: Notify compliance administrators when sensitive data is detected in Power BI, enabling proactive review and remediation.</li> <li><strong>Override with justification</strong>: Allow authorized users to override DLP blocks with a documented business justification, creating an audit trail of intentional sensitive data sharing decisions.</li> </ul>

<h3>DLP Policy Configuration for GDPR</h3>

<ol> <li>Navigate to <strong>Microsoft Purview compliance portal, then Data Loss Prevention, then Policies</strong></li> <li>Create a new policy scoped to <strong>Power BI</strong> (available as a DLP location alongside Exchange, SharePoint, Teams, etc.)</li> <li>Select sensitive information types relevant to GDPR: EU National Identification Numbers, EU Passport Numbers, EU Social Security Numbers, EU Tax Identification Numbers, EU Debit Card Numbers, EU Health Insurance Numbers</li> <li>Configure actions: Policy tip (warning), block external sharing, send incident report to DPO (Data Protection Officer)</li> <li>Test in <strong>simulation mode</strong> first to identify false positives before enforcing</li> </ol>

<h2>Microsoft Purview Integration for Power BI Governance</h2>

<p><a href="/blog/microsoft-purview-power-bi-governance">Microsoft Purview</a> provides the unified governance layer required for GDPR accountability across your Power BI estate.</p>

<h3>Data Catalog and Classification</h3>

<ul> <li><strong>Automatic scanning</strong>: Purview scans Power BI semantic models, identifying tables, columns, measures, and their sensitivity classifications. The scan results appear in the Purview Data Catalog alongside data assets from Azure SQL, Synapse, Fabric Lakehouse, and other sources.</li> <li><strong>Classification labels</strong>: Purview automatically classifies columns containing PII (names, emails, addresses, phone numbers, financial identifiers) using built-in and custom classification rules. This provides an automated inventory of personal data across all Power BI models.</li> <li><strong>Business glossary</strong>: Define GDPR-relevant terms (personal data, special category data, data subject, processing purpose) in the Purview business glossary and link them to specific columns and tables. This creates a living GDPR data inventory that maps directly to your Power BI assets.</li> </ul>

<h3>Data Lineage</h3>

<p>Purview automatically maps the complete data lineage from source systems through ETL pipelines to Power BI semantic models and reports. For GDPR, lineage answers critical questions:</p>

<ul> <li><strong>Where does personal data originate?</strong> Trace a PII column in a Power BI report back through Fabric pipelines to the source database and table.</li> <li><strong>Where does personal data flow?</strong> Identify every Power BI report, dashboard, and dataflow that consumes a specific personal data column.</li> <li><strong>Who has access?</strong> Combined with workspace permissions and RLS, lineage shows the complete access chain from source to consumer.</li> <li><strong>What happens during erasure?</strong> When processing a DSAR, lineage shows every system and Power BI artifact that needs to be refreshed after source deletion.</li> </ul>

<h2>Data Protection Impact Assessments (DPIAs) for Power BI</h2>

<p>Article 35 of GDPR requires a Data Protection Impact Assessment (DPIA) when processing is likely to result in high risk to data subjects. Power BI deployments that process personal data at scale—especially in healthcare, financial services, or government—typically require a DPIA.</p>

<h3>When a DPIA Is Required for Power BI</h3>

<ul> <li>Processing special category data (health, biometric, genetic, racial/ethnic, religious, political, sexual orientation, trade union membership) in Power BI reports</li> <li>Systematic monitoring of employee performance or behavior through Power BI dashboards</li> <li>Large-scale profiling or scoring of individuals (customer segmentation, risk scoring, credit assessment) visualized in Power BI</li> <li>Combining personal data from multiple sources into a Power BI semantic model for cross-referencing</li> <li>Processing personal data of vulnerable populations (patients, students, welfare recipients) in Power BI</li> </ul>

<h3>DPIA Template for Power BI Deployments</h3>

<table> <thead><tr><th>DPIA Section</th><th>Power BI-Specific Content</th></tr></thead> <tbody> <tr><td>Processing description</td><td>Describe the Power BI semantic model, data sources, refresh frequency, and who accesses reports</td></tr> <tr><td>Necessity and proportionality</td><td>Justify why personal data (not anonymized or aggregated data) is required for the analytical purpose</td></tr> <tr><td>Data minimization assessment</td><td>Document which PII columns are included and why each is necessary; document excluded columns</td></tr> <tr><td>Risks to data subjects</td><td>Unauthorized access to PII in reports, data breach via export, re-identification from aggregated data, cross-border transfer risks</td></tr> <tr><td>Mitigating controls</td><td>RLS, sensitivity labels, DLP policies, Multi-Geo, audit logging, export restrictions, workspace access controls</td></tr> <tr><td>Residual risk assessment</td><td>Evaluate remaining risk after controls; determine if residual risk is acceptable or requires DPA consultation</td></tr> <tr><td>DPO sign-off</td><td>Data Protection Officer review and approval with date</td></tr> </tbody> </table>

<p>Store completed DPIAs in your organization's compliance repository and review them annually or whenever the Power BI deployment changes significantly (new data sources, new user populations, changes to data residency).</p>

<h2>Consent Management in Power BI Analytics</h2>

<p>When processing personal data based on consent (GDPR Article 6(1)(a)), you must ensure that only data with valid, specific, informed consent is included in Power BI analytics.</p>

<ul> <li><strong>Consent as a data attribute</strong>: Include a consent status column in your data model (ConsentGranted: Yes/No, ConsentDate, ConsentScope). Use this column in <a href="/blog/power-bi-row-level-security">Row-Level Security</a> rules to automatically exclude records without valid consent from Power BI reports.</li> <li><strong>Purpose-specific consent</strong>: GDPR requires consent to be specific to each processing purpose. If a customer consented to marketing emails but not analytics profiling, their data should be excluded from profiling models. Implement purpose-specific consent flags in the source system and filter at the Power BI model level.</li> <li><strong>Consent withdrawal</strong>: When a data subject withdraws consent, update the consent status in the source system, and the next Power BI refresh automatically excludes their data. Ensure refresh frequency is sufficient to honor withdrawal within a reasonable timeframe (GDPR does not specify an exact timeframe, but regulators expect "without undue delay").</li> <li><strong>Consent audit trail</strong>: Maintain an immutable log of consent grants and withdrawals in the source system. Include consent metadata in Purview data lineage to demonstrate that Power BI analytics only process data with valid consent.</li> </ul>

<h2>Cross-Border Data Transfers in Power BI</h2>

<p>GDPR Chapter V restricts transfers of personal data to countries outside the EU/EEA unless adequate safeguards are in place. Power BI cloud architecture involves Microsoft data centers globally, making cross-border transfer compliance essential.</p>

<h3>Transfer Mechanisms for Power BI</h3>

<table> <thead><tr><th>Mechanism</th><th>Description</th><th>Power BI Application</th></tr></thead> <tbody> <tr><td>EU Data Boundary</td><td>Microsoft commitment to process EU data in EU data centers</td><td>Default for EU tenants; covers Power BI Service processing</td></tr> <tr><td>Multi-Geo</td><td>Workspace-level data residency control</td><td>Assign EU workspaces to EU regions (Premium/Fabric required)</td></tr> <tr><td>Standard Contractual Clauses (SCCs)</td><td>EU-approved contractual framework for transfers</td><td>Microsoft Data Protection Addendum includes SCCs covering all Microsoft cloud services including Power BI</td></tr> <tr><td>Adequacy Decisions</td><td>EU recognition that a country provides adequate protection</td><td>Transfers to countries with adequacy decisions (UK, Japan, South Korea, etc.) are permitted without additional safeguards</td></tr> <tr><td>Binding Corporate Rules</td><td>Intra-group transfer approval from DPA</td><td>For organizations with approved BCRs, Power BI data transfers within the corporate group are covered</td></tr> </tbody> </table>

<h3>Practical Architecture for EU Data Residency</h3>

<ol> <li><strong>EU-resident tenant</strong>: If possible, use an EU-based Microsoft 365 tenant (billing address in EU member state). This makes EU the default data location.</li> <li><strong>Multi-Geo for non-EU operations</strong>: Use Multi-Geo to assign non-EU workspaces to their respective regions while EU workspaces stay in EU regions.</li> <li><strong>Gateway architecture</strong>: Deploy on-premises data gateways in EU data centers for EU data sources. Do not route EU personal data through non-EU gateways.</li> <li><strong>Fabric capacity region</strong>: When using Microsoft Fabric, create EU-region capacities for EU data workloads. Fabric capacities are region-specific.</li> <li><strong>Document the transfer assessment</strong>: Under GDPR Article 46, document a Transfer Impact Assessment (TIA) evaluating the risks of any cross-border transfer and the safeguards in place. Microsoft's Data Protection Addendum and EU Data Boundary commitment provide strong safeguards for the TIA.</li> </ol>

<h2>Audit Logging and Monitoring for GDPR Accountability</h2>

<p>GDPR's accountability principle requires demonstrating compliance—not just being compliant. Power BI provides comprehensive audit logging that forms the evidence base for GDPR accountability.</p>

<h3>Power BI Activity Log</h3>

<p>The Power BI activity log captures every user and admin action:</p>

<ul> <li><strong>Report views</strong>: Who viewed which report, when, from which IP address</li> <li><strong>Data exports</strong>: Who exported data from which report, in which format (Excel, CSV, PDF), and when</li> <li><strong>Sharing actions</strong>: Who shared which report or dashboard with whom, including external sharing</li> <li><strong>Admin actions</strong>: Tenant setting changes, workspace permission modifications, capacity assignments</li> <li><strong>Sensitivity label changes</strong>: Who changed a label, from which label to which, and when</li> <li><strong>Dataset refresh history</strong>: Refresh timestamps demonstrating data freshness for accuracy compliance</li> </ul>

<h3>Integrating with SIEM</h3>

<p>For enterprise GDPR monitoring, export Power BI audit logs to your SIEM (Microsoft Sentinel, Splunk, QRadar) for:</p>

<ul> <li><strong>Anomaly detection</strong>: Alert on unusual data export volumes (potential data exfiltration), after-hours access to sensitive reports, or access from unusual locations</li> <li><strong>DSAR response</strong>: Query audit logs to identify every Power BI report and dashboard a data subject's data appeared in, supporting the Right of Access response</li> <li><strong>Compliance reporting</strong>: Generate periodic GDPR compliance reports showing access patterns, export activity, label coverage, and DLP policy matches for DPO review</li> <li><strong>Retention</strong>: Power BI retains activity logs for 30 days by default. Export to long-term storage (Azure Log Analytics, SIEM) for GDPR's accountability obligation, which may require multi-year retention.</li> </ul>

<h2>Row-Level Security (RLS) for GDPR Purpose Limitation</h2>

<p>GDPR's purpose limitation principle requires that personal data is only used for the specific purpose for which it was collected. In Power BI, <a href="/blog/power-bi-row-level-security">Row-Level Security (RLS)</a> is the primary technical control for enforcing purpose limitation:</p>

<ul> <li><strong>Department-based RLS</strong>: HR users see only HR-relevant employee data. Finance users see only finance-relevant data. Marketing sees only marketing consent-granted customer data.</li> <li><strong>Geographic RLS</strong>: EU data controllers see only EU data subject records. US operations see only US records. Prevents cross-border data access that might trigger additional GDPR transfer requirements.</li> <li><strong>Consent-based RLS</strong>: Filter rows where ConsentStatus = "Granted" for the specific analytical purpose. Users only see records with valid consent for analytics.</li> <li><strong>Time-based RLS</strong>: Combine with storage limitation—filter out records older than the retention period defined in your GDPR records of processing.</li> </ul>

<p>RLS rules are defined in the semantic model using DAX filter expressions and enforced server-side. Users cannot bypass RLS—even direct XMLA endpoint queries respect RLS filters. Test RLS thoroughly using the "View as Role" feature in Power BI Desktop and the <code>Test-PowerBIRow</code> PowerShell cmdlet in the service.</p>

<h2>GDPR Compliance Checklist for Power BI Deployments</h2>

<h2>Common GDPR Compliance Mistakes in Power BI</h2>

<ul> <li><strong>Importing full PII when only aggregates are needed</strong>: If the report shows department-level headcount, do not import individual employee names and IDs. Aggregate at the source or ETL layer.</li> <li><strong>No sensitivity labels</strong>: Unlabeled Power BI assets make it impossible to apply consistent protection policies. Enable mandatory labeling to close this gap.</li> <li><strong>Ignoring exports</strong>: Power BI users can export data to Excel, CSV, and PDF. Without DLP policies and sensitivity label export protection, personal data leaves the governed Power BI environment unprotected.</li> <li><strong>No DSAR process for Power BI</strong>: Organizations often handle DSARs for source systems but forget that Power BI retains cached copies of personal data. Include Power BI refresh in your DSAR workflow.</li> <li><strong>Relying on workspace permissions alone</strong>: Workspace permissions control who can see a report but not which rows within the report. Without RLS, any workspace member sees all data in the model, including data they should not access for GDPR purpose limitation.</li> <li><strong>No audit log retention</strong>: Power BI's default 30-day log retention is insufficient for GDPR accountability. Export to long-term storage from day one.</li> <li><strong>Sharing reports externally without safeguards</strong>: External sharing (B2B collaboration) can transfer personal data to external Azure AD tenants. Ensure external sharing is restricted to appropriate sensitivity labels and that SCCs are in place with external partners.</li> <li><strong>Not updating DPIAs</strong>: A DPIA completed during initial deployment becomes stale when data sources, user populations, or processing purposes change. Review annually or on significant change.</li> </ul>

<h2>GDPR and Microsoft Fabric: Enhanced Compliance Capabilities</h2>

<p><a href="/blog/getting-started-microsoft-fabric-2025">Microsoft Fabric</a> extends Power BI's GDPR compliance capabilities with:</p>

<ul> <li><strong>Unified governance</strong>: Fabric's OneLake provides a single governance layer across data engineering, data science, and BI workloads. Sensitivity labels, access policies, and audit logging apply consistently whether data is accessed via a Fabric notebook, SQL endpoint, or Power BI report.</li> <li><strong>Data lineage across workloads</strong>: Purview integration traces data from ingestion (Fabric pipelines) through transformation (notebooks, dataflows) to presentation (Power BI reports), providing complete GDPR lineage documentation.</li> <li><strong>Managed private endpoints</strong>: Fabric supports managed private endpoints for connecting to on-premises and cloud data sources without public internet exposure, reducing cross-border transfer risk.</li> <li><strong>Git integration for audit trails</strong>: Semantic model definitions, including RLS rules and sensitivity labels, stored in Git provide an immutable change history—supporting GDPR accountability by documenting who changed what, when, and why.</li> <li><strong>Capacity-level region control</strong>: Fabric capacities are created in specific Azure regions, providing data residency control at the compute and storage level.</li> </ul>

<p>GDPR compliance in Power BI is not a one-time project—it is an ongoing operational discipline that spans data architecture, access controls, classification, monitoring, and organizational processes. The organizations that achieve sustainable compliance are those that embed GDPR principles into their Power BI governance framework from the start rather than retrofitting controls after deployment.</p>
