If you’re evaluating Palo Alto Prisma Access 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 Palo Alto Prisma Access sometimes isn’t the right pick: Non-Palo-Alto-anchored buyers (Zscaler / Cloudflare / Netskope better), mid-market without dedicated network team, or buyers wanting transparent published pricing. See full “worst for” verdict →
