Tessian

Tessian is an innovative AI-powered email security platform that focuses specifically on preventing human error and protecting organizations from advanced email-based threats. Unlike traditional secure email gateways, Tessian uses machine learning to understand human behavior and communication patterns, enabling it to detect and prevent threats that bypass conventional security measures. The platform excels at preventing data loss incidents, stopping spear-phishing attacks, and protecting against CEO fraud by analyzing the context and intent of email communications. Tessian's behavioral analysis engine learns from billions of email interactions to understand normal communication patterns within each organization, identifying when emails deviate from expected behavior. This behavioral approach allows Tessian to catch sophisticated attacks that use social engineering and contextual information to appear legitimate. The platform provides real-time protection with intelligent warnings that help users make better security decisions without disrupting productivity. What sets Tessian apart is its focus on the human element of cybersecurity, recognizing that people are often the weakest link in security chains and providing tools to strengthen human decision-making. The AI continuously learns from user interactions and feedback to improve accuracy and reduce false positives. Trusted by major organizations including NHS, Schroders, and Greenhill, Tessian has proven its effectiveness in preventing costly data breaches and protecting sensitive information. The platform integrates seamlessly with existing email infrastructure and provides detailed analytics on threat landscape and user behavior patterns.
