Tessian, an email security company that focuses on human error, today announced that it raised $65 million in Series C funding. The company has raised $123.7 million in total and its valuation is now $500 million.
The London, United Kingdom-based company leverages machine learning to prevent attacks that rely on email and social engineering. It describes its solution as “human layer security.”
The company builds behavioral models for all employees and uses them to automatically detect security threats. Furthermore, by notifying employees of these issues, it aims to help improve individual security behaviors.
Tessian says it can keep enterprises safe from business email compromise, data exfiltration, phishing, and accidental data loss.

The funding round was led by March Capital, with participation from existing investors Accel, Balderton Capital, Latitude and Sequoia Capital, and new investor Schroder Adveq.
“People make 35,000 decisions every day; it just takes one wrong decision or one instance of human error for an employee to cause a catastrophic security breach. We’re tackling the biggest threat to enterprise security,” said Tim Sadler, co-founder and CEO at Tessian.
