Darktrace Says Microsoft 365 API Plus Journaling Can Reduce Email Threat-Detection Delays

· Original article ↗

Summary

Darktrace says its API-plus-journaling integration for Microsoft 365 receives messages faster than API-only ingestion, reporting lower median and average latency in customer deployments and recommending the approach for organizations that can use journaling.

Key points

  • API-only integrations may analyze messages after delivery and can experience delays from Microsoft Graph notifications and retries, according to Darktrace.
  • With journaling, a copy of the raw email is received during transport for analysis before the message reaches the inbox.
  • Darktrace’s customer-deployment measurements reported median latency of 0.53 seconds with API plus journaling versus 1.31 seconds with API-only.
  • The company reported a raw mean of 0.75 seconds with journaling versus 21.88 seconds with API-only, attributing the difference to reduced long-tail delays.
  • Darktrace says journaling can operate alongside Microsoft’s native defenses and avoid variability from API notification delivery.
  • The company recommends API plus journaling for speed and reliability, while retaining API-only deployment for organizations unable to use journaling.
