## Overview

Zscaler defined [Zero Trust Network Access](https://startwithidentity.com/guides/fundamentals/what-is-zero-trust/) at enterprise scale and is the reference Security Service Edge (SSE) platform. Zscaler Internet Access (secure web gateway), Zscaler Private Access (ZTNA), and Zscaler Digital Experience together replace the legacy stack of VPNs, web proxies, and backhauled traffic with identity-aware access delivered from a large global cloud.

## What it is good at

Scale and breadth. Zscaler operates one of the largest security clouds, with points of presence worldwide, which is decisive for global enterprises that need consistent, low-latency access everywhere. ZPA delivers true per-application access that never exposes the network, shrinking the attack surface and eliminating lateral movement that VPNs allow. The platform is mature, well integrated with major identity providers for policy signals, and backed by deep support and a large partner ecosystem.

## Where it falls short

This is enterprise-tier software with enterprise-tier pricing and a real deployment program; it is rarely the right fit for cost-sensitive mid-market or small teams. It is an access and network-security platform, not an identity provider, so it consumes identity from your IdP rather than managing it. Developer-centric, self-serve infrastructure access is better served by lighter tools like [Tailscale](https://startwithidentity.com/vendors/zero-trust/tailscale/) or [Cloudflare](https://startwithidentity.com/vendors/zero-trust/cloudflare/).

## Pricing

Quote-based and premium, by user and module across the ZIA, ZPA, and ZDX suite. Budget for a multi-quarter migration off legacy gateways and VPN.

## Best for, and who should look elsewhere

Choose Zscaler for large, global enterprises consolidating secure web gateway, VPN, and ZTNA onto one proven SSE platform. Mid-market and developer-led teams should look at Cloudflare or Tailscale; compare [Cloudflare vs Zscaler](https://startwithidentity.com/compare/cloudflare-vs-zscaler/).

## Bottom line

The enterprise SSE leader for global organizations replacing legacy network security, priced and scoped accordingly.
