Tessian pulls in $42m in Sequoia-led Series B round

Machine intelligent security platform Tessian has raised $42m in a Series B funding round led by Sequoia.

The investment round follows a period of rapid expansion for the company, with Tessian reporting growth of over 300 per cent. The company has said it intends to use the new funding to invest in research and development and to expand their product offering.

The tech investment giant Sequoia was joined in the round by Latitude and existing investors Balderton Capital and Accel.

Tessian’s mission is to automatically protect individuals and enterprises from cybersecurity threats, keeping the world’s most sensitive data and systems private and secure.

The machine intelligent email security platform automatically prevents security threats like misaddressed emails, data loss and non-compliance. Its technology analyses enterprise email networks to understand normal and abnormal email sending patterns and behaviours. The startup then detects anomalies in outgoing emails and warns users about potential mistakes, before the email is sent.

Tessian co-founder and CEO Tim Sadler said, “We’ve entered the third era of enterprise cybersecurity. In the early days, network security sufficed. Then cloud apps and mobile devices proliferated, and we adopted endpoint protection. But in spite of these protections, data breaches are at an all-time high. The reason is humans.

“People are the most important decision makers in the enterprise and process extremely sensitive information on a daily basis, yet they’re more vulnerable than ever before. Tessian’s mission is to help organisations protect people processing data using technology that empowers, rather than restricts the way they work.”

Earlier this week, data security start-up Ionic Security raised $40m in a Series E funding round led by JPMorgan Chase & Co, as the company secured a number of strategic partnerships.
