Data Loss Prevention via Microsoft Purview: stop sensitive data leaving where it should not.
DLP prevents accidental and intentional data leakage: credit card numbers in emails, PDPL-regulated personal data uploaded to consumer cloud, source code sent to personal accounts, financial data shared externally. We deploy Microsoft Purview DLP across email, M365 apps, endpoints, and SaaS apps, with policies tuned to your regulatory context (PDPL, DFSA, ADGM, DHA, NESA).

Six channels DLP monitors and controls.
Email DLP
Outbound email scanned for sensitive patterns: credit card numbers, ID numbers, PDPL personal data, financial figures, source code. Block, encrypt, or warn based on policy. Email channel is the most common data-leakage vector.
M365 apps DLP (SharePoint, OneDrive, Teams)
Sensitive files in SharePoint and OneDrive flagged or restricted from external sharing. Teams messages and shared files scanned. External-sharing notifications. Sensitivity-label inheritance.
Endpoint DLP
Defender for Endpoint scans for sensitive data being copied to USB, printed, uploaded to consumer cloud (Dropbox, Gmail, WhatsApp Web), screen-captured, or copied to unauthorised apps. Block or warn based on policy.
SaaS app DLP
Microsoft Defender for Cloud Apps (formerly MCAS) extends DLP coverage to non-Microsoft SaaS: Salesforce, Box, Dropbox, Google Workspace, ServiceNow, Slack. Sensitive data uploads, downloads, and sharing flagged.
Sensitivity labelling
Manual and auto-applied sensitivity labels (Confidential, Highly Confidential, Public). Labels travel with documents: encryption, watermarks, access restrictions. AI-powered auto-classification with Purview.
Insider risk monitoring
Insider Risk Management (Purview) detects risky behaviour patterns: data hoarding, unusual access, departing-employee exfiltration. Investigations workflow for HR and security collaboration.
Four reasons clients pick our DLP work.
PDPL-tuned policies
Generic DLP templates miss UAE-specific sensitive-data patterns: Emirates ID, UAE bank account formats, ADCB / Emirates NBD / FAB IBANs, DLD property reference numbers. We tune detection patterns to UAE context.
Low false-positive operating model
DLP fails when alert noise overwhelms the SOC. We pilot policies before enforcement, tune thresholds, suppress known-good patterns, and rotate user education before hard-blocking. End-state: alerts that matter, blocks that are warranted.
Integrated with Sentinel and SOC
DLP alerts feed Microsoft Sentinel SIEM. SOC analysts triage within SLA. False-positive feedback loop back to policy tuning. DLP is part of the security operating model, not a parallel system nobody monitors.
Phased rollout: detect, warn, block
DLP rollouts succeed in three phases: monitor-only (detect what is happening), warn users (educate without blocking), block (enforce). We sequence carefully so business operations are not disrupted on day one.
Six business profiles where DLP is essential.
Financial services
Customer financial data, transaction records, KYC documents. DFSA / ADGM data-handling controls.
Healthcare
Patient records, medical history, clinical data. DHA / DOH data-handling, PDPL alignment.
Retail (PCI scope)
Payment card data, customer profiles, transaction logs. PCI DSS scope reduction via DLP.
Professional services
Client confidential documents, M&A material, IP. BEC and accidental-share risk mitigation.
Manufacturing
Proprietary designs, formulations, customer lists. IP protection from insider exfiltration.
Education
Student records, exam content, research data. KHDA data-handling, PDPL alignment.

Four phases from policy design to enforced DLP in 8-12 weeks.
- 1
Sensitive data discovery and policy design
2-3 weeks
Workshops to identify sensitive data categories. Sample-data classification scan. Policy design: what to detect, what to do (audit, warn, block). Output: written DLP policy framework.
- 2
Monitor-only pilot
2-3 weeks
DLP policies deployed in audit-only mode. Real traffic monitored without user-facing impact. Baseline false-positive rate measured. Policies tuned before user-facing rollout.
- 3
Warn-mode rollout
2-3 weeks
User-facing warnings activated. Users see "this looks sensitive, are you sure?" prompts. User education campaign rolled out. Adoption and behaviour change measured.
- 4
Block-mode and ongoing
2-3 weeks plus continuous
Block enforcement for highest-sensitivity policies. Continuous tuning. Quarterly review of false-positive rate. Annual policy refresh as data landscape evolves.
“Our compliance team had been raising DLP as a gap for two years. We finally deployed Purview DLP across email, OneDrive, and endpoints. The monitor-only phase showed us 200+ accidental external shares of sensitive data per month, none of which we had visibility on before. Warning-mode reduced that to ~50 per month as users adjusted behaviour. Block-mode now stops the residual. Our annual compliance audit went smoother than the prior year.”
