Zscaler Competitors in 2026: Who Competes With Zscaler and How They Differ

Zscaler built the cloud-proxy security service edge (SSE) category, and it still sets the bar. That's exactly why every serious security vendor now pitches itself against it. If you're mapping Zscaler competitors heading into 2027, the useful question isn't "who else sells SSE?" It's "who solves the problem differently, and where does each one actually beat Zscaler?"

This guide maps the nine Zscaler competitors that show up most in real evaluations: what each one is, how its architecture differs, where it wins, and where Zscaler still has the edge. If you've already decided to leave and want a ranked shortlist, jump to our best Zscaler alternatives for 2027.

Where Zscaler stands going into 2027

Zscaler isn't standing still. A quick read of the 2026 record:

• Still a Gartner Leader. Zscaler, Palo Alto Networks, and Netskope were each named Leaders in the 2026 Gartner Magic Quadrant for Security Service Edge, according to the vendors' own announcements.
• Growing fast. Zscaler reported fiscal Q4 2026 revenue and ARR each up 25% year over year.
• All in on AI security. AI Protect launched in January 2026. In May, Zscaler announced its intent to acquire Symmetry Systems. At Zenith Live in June, it introduced AI Broker (for agent-to-agent and MCP traffic), Endpoint AI Security (browsers, extensions, and local AI tools), and an AI Access Graph built on the Symmetry technology.

The core architecture hasn't changed: traffic leaves the device through Zscaler Client Connector (or a tunnel, or a PAC file), lands at a Zscaler data center, gets inspected, and continues to its destination. Zscaler Internet Access (ZIA) handles the web. Zscaler Private Access (ZPA) handles internal apps.

So every competitor below is answering one question: do you copy that model and compete on features, wrap it in a bigger platform, or change where inspection happens?

Three ways to compete with Zscaler

Sort the competitive landscape by architecture first. Features change every quarter. Architecture doesn't.

• Cloud-proxy SSE peers. Netskope, Forcepoint, and Microsoft Entra Internet Access route traffic to their own cloud for inspection, the same model as Zscaler, and compete on CASB depth, DLP, or ecosystem fit.
• Platform and network-first SASE. Palo Alto Prisma Access, Cisco Secure Access, Cato Networks, Fortinet FortiSASE, and Cloudflare One bundle SSE with firewalls, SD-WAN, or a global edge network. Inspection still happens in the vendor's cloud or points of presence.
• On-device SSE. dope.security moves the proxy onto the laptop itself. SSL inspection, URL filtering, Cloud Application Control, and AI-powered DLP run on the endpoint, and traffic goes straight to the internet. No stopover data center.

Zscaler competitors at a glance

The 9 Zscaler competitors, head-to-head

Netskope vs. Zscaler

Netskope is Zscaler's closest like-for-like competitor. Both are cloud-proxy SSE platforms, both are Gartner SSE Leaders, and both are public companies (Netskope trades on Nasdaq as NTSK). Netskope's edge has always been CASB and data protection for sanctioned SaaS. In March 2026 it launched Netskope One AI Security, including an AI Gateway, AI Guardrails, and an Agentic Broker for MCP traffic.

The difference that matters: feature emphasis, not architecture. Traffic still steers to Netskope's NewEdge data centers. Deep dive: Zscaler vs. Netskope.

Palo Alto Networks Prisma Access vs. Zscaler

Prisma Access is Palo Alto's cloud-delivered SASE, also a 2026 SSE Leader. It wins when you already run Palo Alto firewalls and want one policy model from data center to remote user. In 2026 Palo Alto pushed hard on Prisma Browser as a control point for agentic AI.

The difference that matters: you're buying into a platform. Great if you're already there, heavy if you're not. More: Zscaler vs. Palo Alto Prisma Access.

Cisco Secure Access vs. Zscaler

Cisco's competitive story changed in 2026. Cisco announced end of sale for Umbrella SIG and DNS, with a last order date of January 31, 2027, and is moving customers to Cisco Secure Access. Renewals run through January 31, 2028, and support ends January 31, 2029, per Cisco's bulletin.

The difference that matters: for Cisco shops, the 2027 decision isn't "Umbrella or Zscaler." It's "migrate to Secure Access, or use the forced migration to re-evaluate." Background: Zscaler vs. Cisco Umbrella.

Cloudflare One vs. Zscaler

Cloudflare One bundles Gateway (SWG), Access (ZTNA), CASB, and DLP on Cloudflare's global edge. It's a natural fit for teams already on Cloudflare for DNS and CDN, and Cloudflare expanded its SASE partner program in 2026.

The difference that matters: inspection runs at Cloudflare's edge instead of Zscaler's data centers. Closer to the user, but still off the device. More: Cloudflare vs. Zscaler.

Microsoft Entra Internet Access vs. Zscaler

Microsoft's Global Secure Access (Entra Internet Access and Entra Private Access) is generally available and ties web and private access policy directly to Entra ID and Conditional Access. For Microsoft 365-centric shops, that's a real pull.

The difference that matters: coverage is strongest inside the Microsoft ecosystem, and its AI prompt controls depend on enabling TLS inspection. Our explainer: What is Microsoft Entra Internet Access?

Cato Networks vs. Zscaler

Cato runs single-vendor SASE on its own private backbone: SD-WAN, SWG, CASB, ZTNA, and firewall-as-a-service in one console. It's a strong pick when you're replacing MPLS and SSE in the same project. Cato raised a $359 million Series G at a $4.8 billion valuation.

The difference that matters: it competes on networking plus security. The inspection model is still a cloud PoP. More: Cato Networks vs. Zscaler.

Fortinet FortiSASE vs. Zscaler

FortiSASE extends the Fortinet Security Fabric to remote users. Fortinet reported FortiSASE billings more than doubling in Q2 2026. It's the default conversation for FortiGate-heavy organizations.

The difference that matters: ecosystem consistency over best-of-breed SSE. More: Zscaler vs. Fortinet.

Forcepoint ONE vs. Zscaler

Forcepoint leads with data protection. Forcepoint ONE combines SWG, CASB, and ZTNA, and the company expanded its AI-native Data Security Cloud with the ARIA assistant in March 2026.

The difference that matters: pick it when DLP drives the decision. It's still a cloud-delivered proxy model. More: Zscaler vs. Forcepoint.

dope.security vs. Zscaler

dope.security is the competitor that changes the architecture instead of the logo. dope.swg is an on-device proxy for Mac and Windows: SSL inspection, URL filtering (allow, warn, block), Cloud Application Control, and Dopamine DLP all run on the endpoint, and traffic flies direct to its destination.

What that changes in practice:

• No detour. Inspection happens before traffic leaves the laptop, so there's no data-center hop to add latency. Up to 4x faster than legacy SWGs, in under 100 MB of RAM.
• Decryption stays local. SSL inspection happens on the device, so user traffic isn't decrypted in a third-party data center.
• AI governance on the endpoint. AI Analytics shows which AI apps are in use, by whom, and whether on personal or enterprise accounts. Cloud Application Control allows the corporate ChatGPT or Claude tenant and blocks personal logins. Dopamine DLP classifies uploads with an LLM instead of regex rules.
• One console. Policy changes push to every endpoint instantly.

Where Zscaler still wins: private app access. ZPA is mature, and dope.security focuses on internet, SaaS, and AI traffic. Teams replacing ZIA with dope.security typically keep their existing ZTNA tool. Full comparison: Zscaler vs. dope.security.

How to pick among Zscaler competitors

Start with why you're looking:

• "We like the cloud-proxy model, we want better CASB." Netskope.
• "We're standardized on a firewall vendor." Prisma Access (Palo Alto) or FortiSASE (Fortinet).
• "Cisco is forcing a migration anyway." Evaluate Cisco Secure Access against at least one non-Cisco option before you sign.
• "We live in Microsoft 365." Entra Internet Access.
• "We're replacing MPLS too." Cato.
• "The detour is the problem." dope.security, the one competitor that removes the data-center hop entirely.

Then run a real pilot. Put the competitor next to ZIA on the same users for a week and compare page load times, ticket volume, and what each one can actually see in AI traffic.

FAQ

Who are Zscaler's biggest competitors?

The most common Zscaler competitors are Netskope, Palo Alto Networks Prisma Access, Cisco Secure Access, Cloudflare One, Microsoft Entra Internet Access, Cato Networks, Fortinet FortiSASE, Forcepoint ONE, and dope.security. Netskope and Palo Alto are the closest peers in the cloud-proxy SSE model. dope.security is the on-device alternative.

Is Netskope better than Zscaler?

It depends on the job. Netskope is generally stronger on CASB and SaaS data protection. Zscaler has the larger footprint and the more mature private access product (ZPA). Both route traffic through their own cloud for inspection, so neither changes the architecture.

Is Cisco Umbrella still a Zscaler competitor in 2027?

Not as Umbrella. Cisco set January 31, 2027 as the last order date for Umbrella SIG and DNS and is moving customers to Cisco Secure Access. Existing subscriptions can renew through January 31, 2028.

What's the difference between a Zscaler competitor and a Zscaler alternative?

"Competitors" maps the market: every vendor that sells against Zscaler and how they differ. "Alternatives" is the buyer's shortlist: what to switch to based on why you're leaving. For that, see our best Zscaler alternatives for 2027.

Which Zscaler competitor doesn't backhaul traffic?

dope.security. It runs the secure web gateway on the device and sends traffic directly to its destination. Every other vendor on this list inspects traffic in its own cloud, edge, or points of presence.
