Tessian develops human layer security software that predicts and stops advanced threats caused by human error across enterprise communication channels. Founded in 2013, the firm operates offices in San Francisco, Boston and London.
Tessian has secured £6.5m in a Series C extension round with participation from Okta Ventures, Citi Ventures, Sozo Ventures, CrowdStrike executives and Fortune 500 CISOs.

The company intends to direct the proceeds towards expanding its platform capabilities beyond email to secure messaging, web and collaboration tools against human error.
From the founder
"For too long, cybersecurity software has focused on securing technology and neglected the security of the people who run the organization."
Tim Sadler
CEO and co-founder at Tessian
Investor perspective
"The biggest threat to enterprise security today is people’s identities and behaviors. With more people working remotely, it’s never been more important for companies to know who their most high risk employees are, the threats they pose to company security, and how to keep them safe – without disrupting their workflow. We saw a huge opportunity with Tessian; by securing the human layer, businesses can stop threats and keep operations running."
