About Zscaler
What does Zscaler do?
Zscaler is a leading cloud security platform built on Zero Trust principles. It securely connects users to applications, workloads, and branches, regardless of location, through the world's largest inline security cloud. Instead of routing traffic through on-premises appliances, Zscaler validates identity and context to enforce security policies, stopping attacks and preventing data loss.
What problem does it solve?
Traditional network security approaches fail for modern, distributed workforces and a multi-cloud world. Zscaler eliminates the attack surface exposed by direct internet and application access, replacing perimeter-based defenses with a scalable, cloud-native approach. It helps organizations stop cyberattacks, prevent data loss, and securely embrace AI initiatives.
Who is it for?
Zscaler is designed for large enterprises and global organizations with complex security needs, especially those supporting remote or hybrid workforces, heavily regulated industries (finance, healthcare), and companies undergoing digital transformation. It is less suited for small teams or individuals seeking a simple, standalone VPN.
Real use cases
Key use cases include providing secure internet access for employees, enabling zero trust private application access, securing all forms of AI usage, and consolidating multiple security point products (SWG, CASB, ZTNA, DLP) into one platform. Over 40% of Global 2000 companies and 500B+ transactions daily are secured by Zscaler.
