CST VerdictBased on our analysis of core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise teams replacing legacy VPN with zero trust will prefer Cato Networks ZTNA for its cloud-native architecture that eliminates the need to manage on-premises infrastructure while enforcing identity-based access across hybrid IT. The platform covers both NIST PR.AA (identity and access control) and PR.IR (infrastructure resilience), meaning you get access policy enforcement without sacrificing visibility into whether your security perimeter actually holds under load. Skip this if your organization runs primarily on-premises and needs deep microsegmentation of internal networks; Cato shines at securing remote access to distributed resources, not re-architecting the datacenter.
