Seed investor GV co-led a $15.5m round for the internet-of-things security technology provider that will go to expanding headcount.

GV, a corporate venturing arm of internet and technology conglomerate Alphabet, co-led a $15.5m series A round for US-based networking cybersecurity technology developer Censys on Wednesday.

The round was co-led by Decibel, an independent venture capital firm launched by networking equipment manufacturer Cisco, and included VC firm Greylock Partners.

Censys has developed a cybersecurity software product that searches the internet for devices connected to a client’s network that may be operating without use of a firewall, therefore making them vulnerable to hackers.

The technology is intended to help enterprises keep tabs on systems such as internet-of-things devices. The funding will support a recruitment drive focused on sales, engineering and leadership staff that is expected to double the company’s headcount to 100 within the next year.

GV and Greylock had already co-led a $2.6m seed round for Censys in late 2018 that also featured unnamed angel investors.

Karim Faris, general partner at GV, said: “The Censys team has made substantial progress laying the groundwork for wide-scale internet scanning, and continues to deliver on its promise of providing better security with data.”
