Understanding the Zscaler Competitors Landscape: A Deep Dive

The shift towards cloud-based architectures and remote work has fundamentally changed how organizations approach security. This evolution has driven the adoption of Secure Access Service Edge (SASE), a framework that converges network and security functions into a unified, cloud-delivered service. Zscaler has emerged as a prominent leader in this space, offering a comprehensive suite of cloud-native security solutions. However, a dynamic Zscaler Competitors landscape exists, with various players competing for market share. This article provides a detailed analysis of Zscaler’s major competitors, examining their strengths, weaknesses, and market positioning.

What Is Zscaler?

Zscaler is a cloud-based cybersecurity company that helps organizations securely connect users, devices, and applications — regardless of location. Instead of routing traffic through traditional on-premise hardware like firewalls or VPNs, Zscaler delivers security directly through the cloud.

Established in 2007 and based in San Jose, California, Zscaler runs one of the most extensive cloud-based security platforms globally. It processes over 200 billion transactions per day, blocking 150+ million threats daily across 185+ data centers worldwide.
