Armorblox, a US-based provider of email security software, has received $30m in a series B round led by Next47, a corporate venture capital arm of industrial equipment and consumer appliance producer Siemens.
Investment firm Polaris Partners filled out the round alongside venture capital firms Unusual Ventures and General Catalyst in addition to undisclosed others.
Armorblox has developed a cybersecurity platform that uses natural language processing and deep learning technology to prevent cyberattacks on businesses’ email communication networks.
The company said more than 9,000 organisations use its platform to prevent attacks on their business email accounts. The funding will be used to expand its engineering, data science and go-to-market teams.
General Catalyst led Armorblox’s $16.5m series A round in February 2019, investing with asset management firm Point72’s VC arm, Point72 Ventures. Its backers include angel investors Ramu Arunachalam, Ron Conway, Robin Vasan, John Thompson, Gerhard Eschelbeck, Oliver Friedrichs and DJ Patil.
