Tessian raises $42m led by Sequoia to protect enterprises from security threats caused by people

Sequoia Capital has backed a London-based cybersecurity startup founded by a trio of former banking analysts, who were surprised how often documents such as deal-term sheets were accidentally emailed to the wrong person.

Tessian Ltd. has received $40 million to fund its growth, according to a statement Wednesday. U.S.-based Sequoia is leading the new funding round. Existing investors Balderton Capital, Accel Partners and LocalGlobe are also participating, the company said.
