Zscaler is a San Jose-based maker of cloud security products with about 2,500 customers. Their product scans internet traffic at a company site and applies that company's security policies to that data.
This $38M infusion is their first outside round. Until now they have been entirely run on internal investment. The money is going to be used to expand sales, marketing, and product development. Sounds like that means more job openings. The company also announced that they are cash flow positive which is always a good sign.
