Enhanced message groups: Improving efficiency in email incident response

Sublime has enhanced its message grouping algorithm to improve the detection and remediation of email attack campaigns by grouping similar messages, even when attackers introduce variations in subject, sender, and content to evade detection. This update leverages set similarity algorithms to identify related messages, enabling faster and more efficient triage and remediation by security analysts. By grouping messages with subtle differences, Sublime reduces alert fatigue, decreases false negatives, and improves overall herd immunity, allowing for automatic remediation across all mailboxes once a single message in a group is flagged as malicious. The improved system helps analysts prioritize and investigate attacks more effectively, streamlining the incident response process and reducing the median time to remediate (MTTR) email-originated incidents.
