Two key elements of Zscaler's distributed, multitenant architecture are the company's Single-Scan, Multi-Action gateways and NanoLog log-reduction technology. SSMA minimizes latency as Zscaler's various applications filter traffic, while NanoLog compresses Web log size as much as 50 times. Together, they bring speed and scalability to the process of applying a company's IT policies to incoming and outgoing Web traffic. Zscaler functionality comes in four modules: Secure, Manage, Comply, and Analyze.
Zscaler's service addresses threats posed by "user-initiated" Internet access, including viruses, spyware, bots, phishing, and peer-to-peer networks. It also offers URL filtering to block access to prohibited sites and manage access to social networking, blogging, and other Web 2.0 sites and applications. Zscaler protects against data leakage and supports IT policy compliance by monitoring HTTP traffic. Monthly subscription fees range from $1 to $5 per user, depending on services used.
Chaudhry has started a half-dozen companies, including AirDefense, CipherTrust, and SecureIT. Kailash, who also worked at AirDefense and CipherTrust, began his career at Wipro when it was a startup.
