Now Available: AI-Powered Data Loss Prevention for Microsoft Exchange Online

The Reality Behind Exchange Online DLP: What Customers Actually Experience

Organizations investing in Microsoft 365 E5 licensing expect enterprise-grade email protection. Yet despite premium security features, customer feedback reveals persistent challenges with Microsoft Purview DLP across Exchange Online environments.

Microsoft deployment specialists report seeing clients deploy Purview on their own, discover a wealth of false positives, and turn off the policies or set them to audit mode. Policies never become useful. This pattern occurs so frequently that many organizations abandon their DLP initiatives entirely, asking later, "Why do we even use Purview if it's broken?"

Customer-Reported Limitations in Exchange Online Protection:

Policy Management Complexity: There are so many configuration options in a Microsoft Purview Data Loss Prevention (DLP) policy that Microsoft's own documentation acknowledges "it's not possible to cover every, or even most configurations." Security teams struggle with the overwhelming number of settings required to create effective policies.

False Positive Overload: Organizations report that the built-in DLP generates a high amount of false positives, leading to unnecessary administrative work and potential disruptions in communication. Without a closed feedback loop, these systems cannot learn from mistakes, perpetuating the same detection errors.

Limited File Format Support: Microsoft Purview DLP does not look into any of the documents like PDF, JPEG, JPG, PNG, DOC, DOCX, XLSX, and lacks the ability to process JPEG, JPG, PNG (including all images and screenshots), and ZIP file formats. This leaves massive blindspots where sensitive data can hide.

Inadequate Content Analysis: The native system performs no thorough document support and does not perform in-depth content analysis across all document types, missing sophisticated exfiltration attempts that embed sensitive data in various formats.

Binary Response Limitations: Customer feedback consistently highlights frustration with Microsoft's "block or allow" approach, which creates unnecessary business friction without providing the nuanced controls modern organizations require.

Data Lineage Blindspots: Microsoft's Purview lacks comprehensive data lineage tracking across the entire data lifecycle. Organizations cannot trace sensitive information from its origin through every touchpoint (download, edit, share) to its ultimate destination, leaving critical gaps in understanding how data moves between Exchange Online, endpoints, and external channels.

Microsoft Defender Integration Gaps: While Microsoft Defender provides endpoint protection, it operates in isolation from Exchange Online DLP policies. Organizations cannot correlate email-based data sharing with endpoint activities, missing sophisticated exfiltration attempts that span multiple channels and failing to provide the unified visibility required for modern Data Loss Prevention.

AI-powered DLP for Exchange Online that actually works

Our Exchange Online integration delivers the precise capabilities that Microsoft Purview cannot provide, addressing the specific pain points identified by actual customers:

Advanced Content Detection

• AI-powered content classification that identifies sensitive data in email bodies, not just attachments
• Computer vision based ML models that extracts and analyzes text from images and screenshots
• Recognition of copy/paste data including credentials, PII, PHI, PCI and proprietary information embedded directly in email text
• Support for 150+ file types including complex archives and specialized formats that Purview cannot process

Granular Policy Control

• Sender/recipient/domain filtering that distinguishes between internal and external communications
• Contextual rules that apply different policies based on recipient categories, sender groups and more
• Executive-specific protections for high-value targets without impacting broader operations
• Department-level policies that balance security with operational requirements

Intelligent Remediation Actions

• Automatic encryption of sensitive content based on recipient and context
• Quarantine capabilities with streamlined review workflows
• Real-time user coaching through contextual policy tips that educate rather than frustrate
• Graduated responses including Blocking emails that match protection level to actual risk, eliminating the false positive burden

Copy/Paste Protection

Stop the most common exfiltration method that native tools miss entirely:

• Detect sensitive data copied directly from documents into email bodies
• Identify structured data formats within message text that bypass attachment controls
• Apply consistent protection whether data appears in attachments or message content across SaaS and AI applications, endpoints and browsers
