The human layer security software provider has added about $9m to its latest round from investors including Okta Ventures and Citi Ventures.

US-headquartered cybersecurity technology developer Tessian lifted its series C round to $74m yesterday having secured an extension featuring identity authentication technology provider Okta and financial services firm Citi. Venture capital firm Sozo Ventures filled out the participants along with executives at cybersecurity services group CrowdStrike and unnamed chief information security officers at unspecified Fortune 500 companies. Okta and Citi took part through their respective investment arms, Okta Ventures and Citi Ventures, in the close likely sized at $9m. It came after a $65m series C round in May this year led by March Capital and backed by Accel, Balderton Capital, Latitude, Schroder Adveq and Sequoia Capital. Founded in the UK in 2013 as CheckRecipient, Tessian provides human layer cybersecurity software which uses machine learning to help organisations prevent data breaches from clerical errors including misdirected emails, misattached files and phishing attacks. Sequoia Capital led a $42m series B round for Tessian in early 2019, investing alongside Latitude, Balderton Capital and Accel, shortly after it was included in Tech Nation’s accelerator scheme Upscale 4.0. Balderton Capital and Accel co-led a $13m series A round for the company the year before featuring Amadeus Capital Partners, Crane Venture Partners, LocalGlobe, Winton Ventures and Walking Ventures. The company secured $2.7m in a 2017 round co-led by Accel and LocalGlobe and filled out by Winton Ventures, Amadeus Capital Partners and Crane Venture Partners.
