These alternatives to Zscaler share its cloud-first philosophy but differentiate on global network architecture, SaaS visibility depth, pricing accessibility, and convergence of networking and security capabilities. Netskope leads in CASB and data protection, Cloudflare Zero Trust offers unmatched pricing transparency and the largest global network, and Cato Networks provides the most architecturally pure single-vendor SASE with a private backbone. These are the strongest alternatives for organizations that have committed to a cloud-delivered security model.

Cato Networks

SASE & Zero Trust
Best fit for

Mid-market and large enterprises wanting a true single-vendor SASE platform with a private global backbone and simplified management

Cato Networks is the pioneer of the single-vendor SASE platform, converging SD-WAN, SWG, CASB, DLP, ZTNA, FWaaS, and advanced threat prevention into a single cloud-native service built on a private global backbone. Unlike competitors that bolt together acquired products, Cato built every SASE component from the ground up on a single software stack and operates its own global backbone of 80+ PoPs connected by SLA-backed private links, providing predictable performance that internet-based SASE solutions cannot guarantee. Cato's architectural purity and simplified management make it particularly attractive for mid-market organizations. In September 2025 Cato made its first acquisition, buying the AI security company Aim Security to add protection for enterprise use of AI applications and agents.

Frequently Asked Questions

A truly cloud-native SASE platform is built from the ground up to run in the cloud rather than being a virtualized version of on-premises appliances. Key indicators include a multi-tenant architecture, global PoP distribution, single-pass inspection engines, and the ability to scale elastically without per-appliance capacity limits. Zscaler, Netskope, Cloudflare, and Cato Networks are all genuinely cloud-native. Platforms from traditional firewall vendors like Palo Alto and Fortinet evolved from on-prem architectures, which can introduce limitations in cloud scalability and feature parity.

Cloudflare actually exceeds Zscaler's network presence with 300+ cities compared to Zscaler's 150+ data centers, though the architectures differ. Cloudflare uses Anycast while Zscaler uses a proxy model. Netskope's NewEdge covers 70+ regions with full compute at every PoP. Cato operates 80+ PoPs on a private backbone with SLA-backed performance. While Zscaler has the largest purpose-built security cloud, Cloudflare's network is larger overall, and Cato's private backbone delivers more predictable performance than any internet-based approach.

Cloudflare Zero Trust is the most accessible, offering a free tier for up to 50 users and paid plans starting at $7/user/month. Cato Networks prices based on sites and users with competitive mid-market positioning. Netskope is priced comparably to Zscaler at the enterprise tier. All three are generally less expensive than Zscaler for equivalent capabilities, with Cloudflare offering the most dramatic cost savings. Often 50-70% less than Zscaler for comparable features.

It depends on your primary requirement. Choose Netskope if CASB and cloud data protection are paramount. It matches or exceeds Zscaler in these areas. Choose Cloudflare Zero Trust if cost and developer-friendly operations matter most. It offers 80% of Zscaler's capabilities at a fraction of the price. Choose Cato Networks if you want the simplest converged networking and security platform with integrated SD-WAN and a private backbone. All three are proven cloud-native platforms that can serve as comprehensive Zscaler replacements.
