Zscaler is a global cloud-based information security company that provides Internet security, web security, next generation firewalls, sandboxing, SSL inspection, antivirus, vulnerability management and granular control of user activity in cloud computing, mobile and Internet of things environments. As of 2015, Zscaler provides automated threat forensics and dynamic malware protection against advanced cyber threats, such as advanced persistent threats and spear phishing for more than 6,000 corporate, government and military organizations with more than 15 million paying users. It provides a cloud-based approach to security as a service. The company was founded in 2008 by Jay Chaudhry, a serial security entrepreneur that previously founded and later sold AirDefense, CipherTrust, CoreHarbor and SecureIT and Kailash, the former chief architect of NetScaler. The company is unique among the private technology company "unicorns" in that it is almost entirely self-funded, has significant recurring revenue, is cash-flow positive, and is more than doubling its business year over year. In 2012, Zscaler raised $5 million in venture capital from Lightspeed Venture Partners plus received a strategic investment from EMC Corporation as part of a $38 million expansion round. Zscaler has a reported company valuation of "well north of $1 billion." On August 3, Zscaler announced a $100 million pre-IPO fundraising led by TPG Capital Growth. On September 23, 2015, Zscaler announced that the $100MM round had been oversubscribed and has been raised to $110 million including a $25 million investment from Google Capital. Zscaler is unusual for a Software as a Service company in that it started out serving the very high end of the market and is now growing downward - most SaaS companies start with the mid-market and grow upward. As of 2015, more than 50 of the Fortune 500 are standardized on Zscaler for their Internet security. The companys largest deployment is the National Health Services of the UK, with 1.6 million employees protected by Zscaler. This is reported to be the largest SaaS deployment of any kind in the world. Other large organizations that have deployed Zscaler include General Electric, United Airlines, Air France, Barclays, Procter and Gamble, Nestle, Huawei, VMware, Epson America, Inc., NBC, Newscorp, the State of North Carolina, the United States Marines and NATO.
