Zscaler Private Access vs. Tailscale

Zscaler Private Access (ZPA) is a cloud-based zero trust solution that securely connects users to private applications hosted in public clouds, data centers, or on-premises environments without relying on traditional VPNs or exposing them to the internet. Built on the principles of zero trust, ZPA ensures that users are authenticated and authorized before granting access, providing application-specific access rather than exposing the network.

Tailscale is a modern, secure, zero-trust connectivity platform. It provides an easy and fast way to securely connect from and to any device or service, anywhere. Built on the WireGuard® protocol, Tailscale enables organizations to create secure mesh networks that communicate between devices and services without the complexities and centralized gateway bottlenecks associated with legacy VPN and networking solutions. Tailscale’s modern identity-native approach allows for end-to-end security, ensuring that data remains protected as it travels between endpoints.
