Tessian is worth it if you use it regularly. Behavioral approach catches sophisticated threats that rule-based filters miss entirely provides good value for the right users.
💰 Bottom line: Enterprise gets you ai-powered email security platform using behavioral analysis to prevent phishing, data loss, and misdirected emails
For Enterprise, here's what that buys you:

Quick comparison (not a full review):
Abnormal Security revolutionizes email protection with behavioral AI that understands normal communication patterns and detects sophisticated threats through anomaly detection. Unlike traditional signature-based solutions, Abnormal establishes baselines of organizational behavior and identifies deviations that signal malicious intent, making it exceptionally effective against never-before-seen attacks. The platform integrates seamlessly with Microsoft 365 and Google Workspace via API, augmenting existing security tools without requiring MX record changes or email routing disruption. Ideal for enterprises seeking advanced protection against business email compromise (BEC), executive impersonation, and account takeover attacks that regularly evade conventional email security gateways.
Abnormal Security: Better if you need Mid-market and enterprise security teams on Microsoft 365 or Google Workspace who need behavioral AI to catch business email compromise and social engineering attacks that traditional email gateways miss.
