If you’re evaluating Fortinet FortiSASE for zero trust network access (ztna), the three strongest independent alternatives in our editorial ranking are Zscaler, Cloudflare One, Tailscale. Each has a different best-fit buyer — the right choice depends on team size and workflow, not on which has the loudest review-site presence.
Why Fortinet FortiSASE sometimes isn’t the right pick: Non-Fortinet shops (Zscaler / Cloudflare / Netskope better), buyers cautious about recent CVE frequency, or organizations wanting cloud-native architecture without legacy networking heritage. See full “worst for” verdict →

Tailscale
WireGuard-based mesh VPN with developer-first UX.
Engineering teams, devops, and SMB-to-mid-market organizations (10-2,000 employees) wanting frictionless WireGuard mesh access rather than full SASE rollouts.
