That is the split. The rest is architecture, packaging, and who runs the platform after you buy it.
When to use each
Use Zscaler if your users already reach the internet and private apps through Zscaler Internet Access (ZIA) and Zscaler Private Access (ZPA). Zscaler describes ZIA as a proxy architecture that inspects TLS traffic at scale, with a secure web gateway, zero trust firewall, IPS, DNS security, cloud sandbox, browser isolation, CASB, and inline DLP. ZPA brokers one-to-one connections between authorized users and specific apps, so users never join the corporate network and apps are not exposed to the public internet.
Use Cloudflare One if you want SASE on the same network that serves and protects your public websites and APIs. Cloudflare One combines Access for Zero Trust application access, a Secure Web Gateway for DNS, network, HTTP, and egress filtering, Cloudflare Tunnel, the Cloudflare One Client on devices, CASB, DLP, Remote Browser Isolation, Email security, and Cloudflare WAN for branches and data centers, under one control plane.
If you only need to secure workforce traffic, both can do the job, so test them with your own users, apps, and identity provider. If you also want one vendor for the public edge, look at scope: Zscaler's product list covers users, workloads, branches, and private apps, and does not include a CDN or a web application firewall for your public websites.
How ZIA and ZPA map to Cloudflare One
Zscaler Internet Access protects users when they browse the internet or use SaaS apps. Its closest Cloudflare One counterpart is the Secure Web Gateway, with CASB, DLP, and Remote Browser Isolation for SaaS and data controls.
Zscaler Private Access connects users to private apps without a VPN. Its closest Cloudflare One counterparts are Access, which authenticates every request to an application, and Cloudflare Tunnel, which connects your apps to Cloudflare through outbound-only connections from the lightweight cloudflared daemon, so the app needs no public IP address.
For user experience, Zscaler Digital Experience (ZDX) detects app, network, and device issues, and Cloudflare One has Digital Experience Monitoring (DEX) for the same job. For branches, Zscaler offers Zero Trust Branch, and Cloudflare offers Cloudflare WAN over IPsec, GRE, or direct interconnect, with Cloudflare Network Firewall as firewall-as-a-service.
These mappings are approximate. Feature depth differs by product and plan, so compare the controls your policies actually use.
Network and coverage
Zscaler says its platform runs in more than 200 data centers. Cloudflare's network page lists 348 cities in more than 100 countries and says every service runs in every data center. The counts are measured differently and do not tell you the latency your users will see. Pilot from the offices and countries where your people work, with your identity provider and your heaviest SaaS apps in the test.
Pricing and packaging
Zscaler's pricing page lists two platform bundles, Essentials Platform and Zscaler Platform, with add-ons for capabilities such as digital experience monitoring, privileged remote access, and Zero Trust Branch. Some products, including ZPA, are also sold on their own. The page lists no prices; buyers contact Zscaler for a quote.
Cloudflare One subscriptions are made of seats. A user consumes one seat when they authenticate through Access or when their device connects through Gateway, however many apps they use. Cloudflare asks SASE buyers to contact its sales team for packaging. Through Vigilbase, Cloudflare One is licensed as Cloudflare Enterprise, in our Interna package for staff and internal apps, and scoped together with Managed Cloudflare operations.
Already run Zscaler?
You do not have to replace Zscaler to use Vigilbase. Vigilbase OS, the cybersecurity operating system, has a native Zscaler connector. Zscaler events land in one auditable, queryable record alongside your other security tools, and the Vigil agent investigates high-severity incidents while Vigilbase analysts handle exceptions.
Log collection and analysis differ by provider, and live response actions run only where Vigilbase OS supports them, which is Cloudflare today. For Zscaler, the investigation returns the steps for your team to complete.
How Vigilbase fits
Vigilbase licenses Cloudflare Enterprise and operates it as Managed Cloudflare; we are not a Zscaler reseller. We can scope Cloudflare One for your users and apps, plan a phased move off VPN or another security service edge, and run Access, Gateway, and incidents after go-live. Agents work from evidence and remediate in scope. Humans set the authority, approve changes when required, and handle exceptions.
If Zscaler is working and the requirement is only workforce access, keep it and connect it to Vigilbase OS. If you want Zero Trust and the public edge on one Cloudflare deployment with an operator on it, that is the conversation we will have.
