AI Email Security · Head-to-Head

Abnormal Security vs Proofpoint

Abnormal Security represents a fundamentally different approach to email security compared to Proofpoint. While Proofpoint operates as a full secure email gateway that inspects content, URLs, and attachments, Abnormal uses behavioral AI to detect anomalies in communication patterns. Abnormal excels at catching socially-engineered attacks that contain no malicious payloads, while Proofpoint provides broader protection across the full spectrum of email threats. Many organizations deploy Abnormal as a supplementary layer behind Proofpoint to catch what the gateway misses.

Choose Proofpoint if you need a comprehensive email security platform that covers the full threat spectrum plus DLP, archiving, and compliance in a single solution.
