Zscaler is a cloud security platform offering Secure Web Gateway and Zero Trust Network Access solutions. Instead of routing traffic through corporate networks, users connect to Zscaler's cloud, which inspects web traffic for threats and enforces security policies (blocking malicious sites, filtering content). For private applications, Zscaler brokers a secure connection between the user and the app based on identity and context, eliminating the need for VPNs while keeping internal services hidden from the internet. By doing so, Zscaler provides fast, secure access for remote and mobile users and simplifies network security in a cloud-first world.

Frequently replaced when teams want private deployments and lower TCO.
