AI-powered email security platform using behavioral analysis to prevent phishing, data loss, and misdirected emails. Now integrated into Proofpoint's email protection suite following the December 2023 acquisition.
Tessian was an AI-powered email security platform that used machine learning and behavioral analysis to protect organizations from email threats caused by human error. Unlike traditional rule-based secure email gateways, Tessian analyzed communication patterns to detect anomalies, catching misdirected emails before they were sent, identifying spear-phishing attempts that bypassed conventional filters, and preventing accidental data exfiltration.
In December 2023, Proofpoint completed its acquisition of Tessian, integrating the company's behavioral AI technology into Proofpoint's email security platform to enhance data loss prevention (DLP) capabilities. The integration resulted in Proofpoint's Adaptive Email DLP offering, announced in March 2024, which combines Tessian's behavioral detection with Proofpoint's threat intelligence and enterprise infrastructure.
