Tessian

Tessian is building the world’s first Human Layer Security platform to automatically secure all human-digital interactions within the enterprise.

Today, our products use stateful machine learning to protect people using email and to prevent threats like spear-phishing, accidental data loss due to misdirected emails, data exfiltration, and other non-compliant email activity. We’ve raised $60m from legendary security investors like Sequoia and Accel and have over 150 employees located in San Francisco and London.
