v1.109

New and Noteworthy

• New correlation rule enhancements:
  • It’s now possible to test correlation rules.
  • Group correlation rules can now specify a minimum number of rules that must match in order for the correlation rule to pass, using MinMatchCount.
  • It’s important to note that both correlation rules and signals can greatly increase Snowflake compute costs. Please see the guidance on both correlation rules and signals on how to ensure you are using them effectively.
• Safeguard against alert storms with the alert limiter functionality.
• Use the CrowdStrike Event Streams log source to ingest logs pulled from CrowdStrike’s Event Streams API.
  • This feature is in open beta, and is available to all customers.
• Use the new Sublime Security integration to ingest Audit, MessageEvent, and Message Data Model (MDM) logs into Panther.
  • Panther-managed detections for Sublime Security logs are coming soon!
• Ingest Apache Avro files into Panther—this enables you to onboard Azure Monitor and Microsoft Defender logs.
  • This feature is in open beta, and is available to all customers.
• Use the event.lookup() function to dynamically fetch Lookup Table and Enrichment Provider data in Python detections.
• The left-hand navigation bar in the Panther Console has been reformatted. For example, the Build option has become Detections, and MITRE ATT&CK is now a tab on the Dashboard homepage. Additionally, Data Models, Helpers, and Packs are now tabs within Detections.

Now Generally Available
