About

Tessian operates as a machine learning-powered email security platform designed to prevent human error and advanced threats in enterprise environments. The platform was acquired by Proofpoint in 2021, integrating its advanced behavioral analysis capabilities into Proofpoint's broader email security ecosystem. Tessian focuses specifically on protecting organizations from email-based risks that traditional security solutions often miss.

The platform employs sophisticated machine learning algorithms to analyze email patterns, user behavior, and communication contexts. This behavioral analysis enables the detection of misdirected emails, data exfiltration attempts, and social engineering attacks. The system learns normal communication patterns for each user and organization, flagging anomalies that could indicate security risks or human error.

Tessian's core offerings include three primary modules addressing different aspects of email security. The Data Loss Prevention module prevents accidental data breaches by identifying when sensitive information might be sent to unintended recipients. The Advanced Threat Protection component detects and blocks sophisticated phishing attempts and business email compromise attacks. The third module focuses on preventing account takeover attacks through continuous behavioral monitoring.

The platform distinguishes itself through its emphasis on preventing human-centric security risks rather than solely focusing on technical vulnerabilities. Traditional email security solutions often rely on signature-based detection or rule-based filtering. Tessian's approach analyzes the human element of email communication, understanding context and intent to identify risks that rule-based systems might miss.

Enterprise organizations across various industries utilize Tessian to reduce email-related security incidents and data breaches. Financial services firms, healthcare organizations, and professional services companies particularly benefit from the platform's ability to prevent accidental data disclosure. The solution integrates seamlessly with existing email infrastructure, including Microsoft 365 and Google Workspace environments.

As part of Proofpoint's security portfolio, Tessian enhances the company's people-centric security approach. The integration provides organizations with comprehensive email protection that addresses both technical threats and human vulnerabilities. This combination strengthens overall email security posture by covering attack vectors that traditional security tools often overlook, making it a valuable component of modern cybersecurity strategies.
