Zscaler, Inc. lineage
Bet that security belonged in a global cloud rather than an appliance, then bought one capability a year to fill the platform out.
What Zscaler, Inc. is made of, and who made it. Every acquisition below is verified against primary sources, with the product line it turned into where that connection is documented rather than inferred.
Founded 2007 in San Jose, California as Zscaler by Jay Chaudhry.
A cloud-delivered secure web gateway, at a time when the answer to web security was a proxy appliance in every office. The architectural claim was that if every user's traffic already leaves the building, the inspection point should be in the cloud rather than backhauled to a data centre.
Founded by Jay Chaudhry, who had already built and sold several security companies. Listed on NASDAQ in 2018.
