Tessian Raises Approx. $9M in Series C Extension

Tessian, a London, UK-based human layer security company, raised approx. $9m in Series C extension funding.

Backers included strategic investment from Okta Ventures, Citi Ventures and Sozo Ventures.

The extension, which also sees investment from executives at CrowdStrike as well as Fortune 500 CISOs, brings the total Series C funds raised to $74m.

The company intends to use the funds to expand its platform’s capabilities beyond email, securing other interfaces like messaging, web and collaboration platforms from incidents of human error.

Led by Tim Sadler, CEO and co-founder, Tessian uses machine learning technology to automatically predict and eliminate 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.

Founded in 2013, the company is backed by renowned investors like Sequoia, Accel, March Capital and Balderton Capital, and has offices in San Francisco, Boston and London.
