Tessian uses machine intelligence to automatically prevent cyber security threats like spear phishing, misaddressed emails (data loss), unauthorised emails and non-compliance.

Tessian is a machine intelligent email security platform that helps enterprises counteract human error and significantly reduce the risk of sensitive data loss. Their software analyses historical email data to learn employees’ conventional sending patterns and the behaviours of enterprise email networks. With this contextual information, Tessian is then able to automatically detect anomalies that represent potential threats and stop them in real-time. It does all of this with virtually no change to end-user behaviour.
