Tessian protects every business's mission by securing the human layer

We're building intelligent security that works for human beings as they are, not how security policies would like them to be. Using machine learning technology, Tessian automatically predicts & eliminates advanced threats on email caused by human error - like data exfiltration, accidental data loss, business email compromise & phishing attacks - with minimal disruption to employees' workflow. As a result, employees are empowered to do their best work, without security getting in their way. You can read more about Human Layer Security here.

Tessian has raised a $74m Series C led by renowned security investors, March Capital (Crowdstrike, Knowbe4), with follow-on from Sequoia, Accel, Balderton, Latitude, Okta, Sozo, Citi & Schroder Adveq, to further our mission to secure the human layer.

Founded in 2013, Tessian is backed by world-class venture capital investors, has hubs in London, San Francisco, Boston, & Austin, & London, & is one of the Top-3 2021 Best Places to Work for Women.
