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.
