Internet security firm Zscaler has announced a $25m continuation of its Series D funding round from Google Capital.

It brings the total raised from the Series D round to $110m. The firm will use the money to fuel further expansion, and build its customer base worldwide.

Zscaler chief executive Jay Chaudhry said: "Our new partnerships will further empower Zscaler to invest in our technology platform and grow our worldwide operations to meet ever increasing demand."

Google Capital Partner Gene Frantz welcomed the investment, saying:

"We are big believers in the two unstoppable technology trends that Zscaler is riding – the rise of mobile computing and the evolution from point solutions hosted on-site to integrated cloud platforms."

Back in August, Zscaler was valued at $1bn,on the back of investment led by Texas private equity firm TPG capital, while earlier this month, Google Capital invested $32.5m in Oscar Health.
