Improved Hashing Detection General Availability

We're excited to announce our new hashing detection capability, designed to simplify how you work with sensitive data across different destinations.

Key Features:

• Automatic Hashing Detection: Segment now intelligently detects when fields contain pre-hashed values and avoids double-hashing them

• Plain Text Support: For un-hashed values, Segment continues to automatically hash according to each destination's requirements

• Simplified Workflows: No configuration needed - the system automatically determines whether values need hashing

This enhancement is valuable for customers with strict data privacy requirements who pre-hash PII before it enters Segment's infrastructure. It prevents match failures caused by double-hashing and eliminates common troubleshooting issues when activating pre-hashed data from warehouses or other systems.

The feature is now available for key advertising and marketing technology destinations, with field-level indicators showing which fields support this capability.
