What Is Themis?

Modified on Thu, Apr 16 at 6:49 AM

Themis is IRONSCALES’ AI-powered analysis engine. It automatically analyses every incident and assigns a confidence score — for example, “90% Phishing” or “70% Spam” — based on email similarity, sender behavior, community data, and historic classifications.

What Does Themis Do?

If the confidence score reaches or exceeds your auto-classification threshold, Themis will automatically classify the incident as Phishing or Spam — no human action needed. This saves time and speeds up incident response.

Themis will never auto-classify an incident as Safe. That decision is always reserved for a human.

Auto-Classification Thresholds

You can set the minimum confidence percentage required for Themis to auto-classify. The recommended defaults are:

ClassificationRecommended ThresholdWhat Happens
Phishing80%Emails quarantined automatically
Spam70%Emails moved to Spam/Junk
VIP Impersonation80%Emails quarantined automatically

Auto-classified incidents appear in the Classified Incidents tab with an Auto-Classified tag. Themis’ algorithm is continuously learning and adapting, so its accuracy improves over time.
