Tessian's Human Layer Security platform uses machine learning to understand human relationships and communication behavior in order to protect businesses from threats executed by people on email.

IT Associate
London, GB
Job Description / Skills Required


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 and eliminates advanced threats on email caused by human error - like data exfiltration, accidental data loss, business email compromise and 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.

Founded in 2013, Tessian is backed by renowned investors like Sequoia, Accel and Balderton and has hubs in San Francisco, Boston, and London.
