AI-powered email security — now part of Proofpoint.
Provides AI-driven email security that scans inbound and outbound messages for data leaks, phishing attempts, and malicious attachments. The system builds user-specific behavior models from historical email metadata, allowing it to flag anomalies without relying on static signatures. It operates as a cloud service that integrates with Google Workspace and Microsoft 365, requiring no client installation. By processing each message in real time, it prevents threats before they reach recipients, reducing the burden on traditional gateway appliances. Key capabilities include automated data loss prevention that redacts or blocks emails containing credit‑card numbers, SSNs, or proprietary code. Phishing detection leverages natural‑language analysis to spot deceptive URLs and impersonation cues. Insider‑threat monitoring watches for unusual bulk‑mailing patterns or off‑hour activity, alerting security teams via Slack or SIEM connectors. Administrators can define granular policies per department, schedule quarterly compliance reports, and audit false‑positive rates through a built‑in analytics dashboard. The service updates its machine‑learning models daily, staying ahead of emerging attack vectors. Tessian serves large enterprises, managed‑service providers, and compliance‑focused teams that need to protect sensitive communications without slowing user productivity. It complements existing email gateways by focusing on behavior‑based detection rather than signature lists. Pricing is available only through a paid subscription, with quotes based on user count and required support level; there is no free tier. Compared with legacy DLP products, Tessian offers faster deployment and continuous model training, though organizations must budget for ongoing license fees and allocate staff to review alerts.
