Tessian Cloud Email Security 
Security teams can no longer rely on legacy, rule-based email security solutions to keep organizations safe. Tessian uses machine learning and behavioral intelligence modeling to accurately detect and prevent advanced email threats that rule-based Secure Email Gateways and built-in security within Microsoft and Google fail to stop.
Tessian detects and prevents advanced threats and data loss on email including accidental data loss, data exfiltration, and advanced phishing attacks like business email compromise, account takeover and social engineering. Inboxes are protected on desktop and on mobile.
Where traditional gateway deployments take months, the Tessian API enables seamless integration for Microsoft 365 clients, whether on premise, in hybrid, or in cloud environments in minutes so you can easily consolidate your security stack. No configuration is required.
Tessian integrates with leading SIEM, SOAR, IAM, ITSM, SEG and phishing training solutions to enhance security insights and orchestrate your workflows, including triage and remediation. No need for static rules while automated reporting helps security teams demonstrate ROI to the board and other stakeholders.
Tessian automatically alerts end-users to detected threats in-the-moment. Contextualized messages deliver memorable and individualized training, tailored to each person’s unique security needs and behaviors. Over time, end-users get better at spotting threats, demonstrate safer security behaviors and comply with data handling policies.
