History and Development

Zscaler was founded in 2008 with the goal of redesigning enterprise network security for the cloud era.

In its early years, the company focused on building a cloud-native security platform capable of protecting distributed corporate environments without relying on traditional firewall infrastructure.

During the 2010s, Zscaler expanded its product capabilities and customer base, introducing solutions for zero-trust access, secure internet gateways, and cloud-application protection.

In 2018, the company completed its initial public offering (IPO) on the New York Stock Exchange, providing capital to support global expansion and product development.

Since then, Zscaler has continued investing in cloud security platforms, threat-intelligence systems, and data-protection technologies, strengthening its role in the enterprise cybersecurity market.
