PRESS RELEASE

SUNNYVALE, Calif., July 19 /PRNewswire/ -- Zscaler, Inc., the market leader in cloud security, today announced that hundreds of organizations -- large and small -- have selected the Zscaler integrated service to protect both email and web traffic. Customers represent various industry verticals, such as financial, healthcare, insurance, retail, legal, manufacturing, energy and more; and the service works equally well with the largest global enterprise to the smallest business. The rapid adoption of Zscaler's security service has been driven by customers' desire to consolidate point products, features and capabilities, and simplify security, products/solutions, and IT administration and management. They are able to do this most effectively with Zscaler, significantly reducing cost, complexity, inefficiencies and overall risk. In related news, Zscaler also today announced the first fully-integrated and most comprehensive email and web security service, immediately available to customers worldwide; the service leverages a powerful proprietary ultralow latency cloud infrastructure consisting of more than 40 data centers worldwide.

Customers say Zscaler reduces risk to their businesses, and when asked why they switched to Zscaler, they point to its: -- Incomparable integration of email and web security services for holistic visibility and unified real-time reporting --Consolidated, simplified security with extended functionality and technology innovation -- Unmatched multi-tenant architecture with 40 datacenters; No hardware or software needed; Single policy follows mobile users --Lowest cost of ownership; cuts overhead and bandwidth in half

Customers in varied industries comment as follows:

--A leading healthcare institution in New Jersey with 3,000 employees, Raritan Bay Medical Center (RBMC), has been enjoying the benefits of Zscaler web security for over a year after replacing its former web filtering solution. As email security became available, it became natural to eliminate its email security appliance as well.

"We have been a happy Zscaler web security customer," said Bob Fairclough, manager of Technology Services at RBMC. "Replacing our email security appliances with Zscaler's email service was almost effortless. Integrated email and web security has provided us holistic reporting and common security policies as well as saved us time and money."

-- Morrison, Brown, Argiz & Farra, LLP, (MBAF) one of the nation's top 50 certified public accounting firms and the leading independent accounting firm in Florida, found Zscaler's integrated security particularly appealing for its large multi-office mobile work force.

"We needed a high degree of protection for our information assets, regardless of their geographical location; a combination of an appliance and SaaS was not really a good fit for us," said Cristian Kutscherauer, CTO. "After evaluating several SaaS vendors, Zscaler came out with the lowest latency and best throughput overall. Its administrative ease and DLP functionalities made us comfortable in selecting Zscaler as our platform for web and email security."

--Zscaler's highly scalable architecture also seamlessly extends itself to large enterprises. A Fortune 500 company with 22,000 global employees replaced three different point products across multiple locations with the single service. This enabled them to tackle emerging Web 2.0 threats and protect against data loss across all channels, including mobile users. --The versatility of Zscaler also resonates with professional organizations such as the Chambre Interdepartementale des Notaires de Paris (CINP). The organization selected Zscaler for its 400 small and medium businesses throughout France. See related press release.

"We are proud to add a diverse array of customers, from the largest global enterprises to small and medium businesses, to our rapidly growing list of customers," said Shrey Bhatia, senior vice president of Worldwide Field Operations at Zscaler. "The market demands comprehensive and integrated security services with enterprise-class functionality. Our purpose-built multi-tenant architecture sets us apart from competitors that are retrofitting traditional proxies to deliver cloud services."
