Zscaler 2025 Pricing, Features, Reviews & Alternatives

Zscaler is a cloud-based secure internet and web gateway designed to help businesses manage IT security across multiple devices, users, corporate infrastructure, and locations. Its ByteScan engine inspects each inbound and outbound byte, Secure Sockets Layer (SSL) traffic, and other inline content from within a unified platform. Zscaler immediately blocks detected threats for all customers and provides protection against corrupt web content including scripts, browser exploits, botnets, and malware callbacks. Enterprises can prioritize business applications and enforce bandwidth policies across corporate networks over recreational traffic to improve employees' productivity. Administrators can also access reports to gain insights into web transactions across multiple geographies according to requirements. Using ZScaler, organizations can monitor users' web application access across streaming, social media, email, and other platforms. Businesses can also control Domain Name System (DNS) requests against malicious destinations and limit or block website access for specific users based on location or URL categories.
