The Challenge
The organization was operating a legacy DLP solution with over 300 policies, resulting in:
• High administrative overhead
• Frequent false positives
• Complex policy maintenance
• Fragmented workflows across departments
The goal was to streamline data protection using Microsoft Purview DLP, reduce policy complexity, and improve detection accuracy while maintaining compliance across business units.
The Solution
Amidas delivered a full-scale deployment of Microsoft Purview DLP and Microsoft Information Protection (MIP), including:
-
End-User DLP Policy Design Workshops
Conducted workshops to align business use cases with Microsoft DLP capabilities. -
Microsoft Purview DLP Implementation
Deployed DLP policies across endpoints and Microsoft 365 services, including Exchange, SharePoint, OneDrive, and Teams. -
Purview MIP Implementation
Enabled manual and auto-labeling policies with encryption and visual markings. -
Post-Deployment Support
Provided documentation, skills transfer, and ongoing advisory.
Key Highlights
01
Policy Optimization
Reduced policy count from 300+ to fewer than 50 by consolidating use cases and leveraging MIP and IRM modules.
02
False Positive Resolution
Implemented rule-level network share exclusions instead of global exclusions, resolving alert noise and improving accuracy.
03
User Testing & Validation
Verified expected behavior with end users, confirming that sensitive data copied to whitelisted shares no longer triggered alerts.
04
Token-Based Support Model
Delivered workshops, inbox testing, and user education using a flexible token system, with remaining tokens allocated for future improvements.
The Result
01
Streamlined DLP policy framework with simplified management
02
Significant reduction in false positives, improving operational efficiency
03
Improved user experience with targeted alerts and reduced disruptions
04
Enhanced compliance posture across departments and regions
