What’s new
FIPs 140-3 compliance
Trellix DLP Discover integrates with OpenSSL to comply with the FIPS 140-3 standard. This integration automatically activates FIPS 140-3 mode at runtime across enterprise systems without manual configuration. All operations comply with federal security mandates and enterprise security standards.
Through this standard, all hardware, software, and firmware modules meet rigorous, independently tested requirements for encryption, key management, and tamper resistance.
For more information, see FIPS 140-3 compliance in Trellix DLP Network and Trellix DLP Discover.
SharePoint Online and OneDrive for Business update
Uses OAuth 2.0 token-based authentication to scan SharePoint Online and OneDrive for Business. This update replaces legacy username and password methods with modern application-based security. It ensures your data discovery scans remain compliant with Microsoft 365 security standards.
Important
On-premises SharePoint environments are not affected by this change and continue to use existing credentials.
For more information, see Configure Modern Authentication (OAuth 2.0) for SharePoint Online and OneDrive Repositories.
