Prevent Advanced Threats and Data Loss

One Cloud Email Security Platform

Providing an Intelligent Approach to Preventing Advanced Email Threats

Strengthen Your Email Security and Unburden Your SOC

Detect and Prevent Threats Coming Into and Going Out of Corporate Inboxes

Advanced Email Threat Prevention

Tessian uses behavioral intelligence modeling, powered by machine learning, to detect and prevent advanced email phishing attacks, ransomware attacks, account takeover (ATO), business email compromise (BEC), and targeted impersonation attacks that legacy email security solutions fail to stop.

Prevent Accidental Data Loss and Insider Threats

Whether accidental or malicious, email related data loss poses significant risk to organizations and rule based DLP solutions are easy to work around. Tessian uses historical email data and behavioral intelligence to detect and prevent email misdelivery and malicious insiders.


Security Teams Work Smarter, Not Harder

Tessian automates and enhances threat detection, prevention and response to free up security teams and allow them to focus on mission critical tasks. Tessian requires zero configuration, and deploys within minutes, integrating with your existing cloud or on-premise email environment.

Build a Smarter Security Culture With In-The-Moment Alerts

Tessian automatically alerts individuals when threats are detected, using tailored and contextualized messages which detail why the threat was flagged and what action to take. Over time, this in-the-moment coaching builds self-efficacy as people get better at spotting threats and drives down risk as end-users are nudged towards safer security behaviors.
