Best Zscaler Alternatives for 2026: A Buyer's Shortlist

If you're shopping for Zscaler alternatives, you probably already know why. Maybe it's the renewal quote. Maybe users in Singapore keep complaining that the internet feels slow. Maybe you need to govern ChatGPT and Claude, and URL categories can't tell a corporate login from a personal one.

Disclosure: dope.security makes an on-device secure web gateway and competes with vendors discussed in this post. We've linked independent sources so you can check our claims.

The reason you're leaving should pick the replacement. This shortlist organizes the leading Zscaler alternatives for 2026 by the problem each one actually solves, then gives you a checklist to hold every option against. Want the full market map instead? See Zscaler competitors in 2026.

The short answer

• Best if latency or privacy is the problem: dope.security, which inspects on the device instead of in a vendor's data center.
• Best like-for-like cloud proxy with stronger CASB: Netskope.
• Best for Palo Alto firewall shops: Palo Alto Prisma Access.
• Best for Cloudflare-native teams: Cloudflare One.
• Best for Microsoft 365-first teams: Microsoft Entra Internet Access.
• Best if you're replacing MPLS too: Cato Networks.
• Best for Fortinet estates: Fortinet FortiSASE.
• Best for DLP-led buyers: Forcepoint ONE.
• Best for Cisco-standardized teams: Cisco Secure Access.

Why teams look for a Zscaler alternative

Zscaler is a capable platform and a 2026 Gartner SSE Leader. Teams don't leave because it doesn't work. They leave for these reasons:

• The detour. Every request goes from the laptop to a Zscaler data center, then to its destination. For a remote, laptop-first workforce, that hop is a daily tax, and it gets worse the farther users are from a point of presence.
• Packaging and price. Zscaler doesn't publish list prices, and capabilities are split across editions and products (ZIA, ZPA, ZDX, data protection, and now AI security). Getting to full coverage usually means buying more of them.
• Operational weight. Client Connector, forwarding profiles, PAC files, GRE or IPsec tunnels, and App Connectors all need care and feeding.
• AI governance. Zscaler shipped a lot of AI security in 2026 (AI Protect, AI Broker, Endpoint AI Security). The question is whether you want those as more modules on a cloud proxy, or built into the agent that already sits on every laptop.

Change the vendor, or change the architecture?

Here's the decision most shortlists skip. Almost every Zscaler alternative is another cloud proxy: traffic still detours through someone's data center or edge for inspection. Swapping one for another can fix price, console, or features. It won't fix the detour.

If the detour is the problem (latency, data residency, regional performance, decryption privacy), you need an alternative that inspects on the device. That's the main architectural difference between dope.security and the other options here.

What a Zscaler replacement has to cover

Before you compare vendors, write down your actual Zscaler footprint. At most companies, it's some mix of:

• ZIA (Zscaler Internet Access): SWG, URL filtering, SSL inspection, cloud firewall.
• ZPA (Zscaler Private Access): ZTNA to internal apps, via App Connectors.
• Zscaler Client Connector: the agent on every endpoint.
• Tunnels and PAC files: for offices and the long tail of unmanaged traffic.
• Add-ons: data protection, sandbox, browser isolation, digital experience monitoring, AI security.

Then hold every alternative against this checklist:

• SSL inspection without sending every byte to a third-party data center, if privacy or residency matters to you.
• Tenant-level Cloud Application Control: allow corporate Microsoft 365, Google Workspace, ChatGPT, and Claude, and block personal logins on the same domains.
• DLP for uploads and AI prompts that classifies content, not just destinations.
• One agent and one console.
• A plan for private apps: a ZTNA replacement, or keeping ZPA (or another ZTNA tool) for a renewal cycle.
• Predictable pricing you can model without a spreadsheet from your account team.

The best Zscaler alternatives for 2026

1. dope.security: if the detour, privacy, or AI governance is the problem

dope.security replaces ZIA with dope.swg, a secure web gateway that runs on the device. SSL inspection, URL filtering, Cloud Application Control, and Dopamine DLP all happen on the laptop (Mac and Windows), and traffic flies direct to its destination. No stopover data center, no tunnels to build, no PAC files.

What it offers:

• Speed. Up to 4x faster than legacy SWGs, in under 100 MB of RAM.
• Privacy. SSL inspection happens on the device, so user traffic isn't decrypted in a vendor's data center.
• AI governance you can act on. AI Analytics shows which AI apps are in use, by which users, on personal or enterprise accounts. Block an app or enforce enterprise-only access from the same screen. Cloud Application Control allows your ChatGPT and Claude tenants and blocks personal logins. Dopamine DLP classifies uploads with an LLM instead of regex rules, covering PII, PCI, PHI, and IP. Ask the Dopamine agent a plain-language question ("is anyone using DeepSeek?") and get an answer in seconds.
• One console. SWG, Dopamine DLP, CASB Neural, SSPM, and AI Analytics, with instant policy push to every endpoint.
• Fast rollout. A Fortune 100 company scaled from 900 to over 18,000 devices in weeks, averaging about 3,000 devices per week through Intune. A mid-market healthcare organization replaced Zscaler and took backhaul out of clinical workflows.

Trade-off: dope.security covers internet, SaaS, and AI traffic. If you rely on ZPA for private apps, keep it (or another ZTNA tool) while you move ZIA. The agent runs on Mac and Windows endpoints, so plan separately for other device types.

2. Netskope: best like-for-like cloud proxy

Netskope is the closest swap for a ZIA customer: another cloud-delivered security platform, with CASB and SaaS data protection as its long-standing strengths. Gartner placed it at the top on execution in its 2026 SASE Platforms Magic Quadrant and praised its "broad and deep" networking and security capabilities and its PoP strategy (SDxCentral). It fits large enterprises that want deep data-centric controls without retraining their team on a new operating model. Watch for: because the model is the same, traffic still steers to Netskope's cloud, so the detour stays, and capabilities span several modules you'll need to map against your ZIA footprint. See top 10 Netskope alternatives.

3. Palo Alto Prisma Access: best for Palo Alto shops

If Palo Alto firewalls already run your perimeter, Prisma Access extends the same policy model to remote users and branches. It has been named a Leader in Gartner's SSE Magic Quadrant three years running, including 2025, alongside Zscaler and Netskope (CRN). It fits organizations that want one vendor and one policy language from the data center to the remote laptop, and already have PAN-OS skills in house. Watch for: you're buying a platform, and the full value assumes more of it, so it's a weaker fit if your goal is less vendor commitment rather than more. See Prisma Access alternatives.

4. Cloudflare One: best for Cloudflare-native teams

Cloudflare One puts Gateway, Access, CASB, and DLP on Cloudflare's global edge, and it's strongest when Cloudflare already runs your DNS and CDN. Gartner placed Cloudflare as the only Visionary in its 2026 SASE Platforms Magic Quadrant and applauded its AI and post-quantum cryptography security work (SDxCentral). It suits developer-led and distributed teams that like API-driven configuration and want one vendor at the edge. Watch for: a Visionary placement reflects a younger enterprise SSE business; DLP depth still trails the long-standing SSE leaders, so test your real DLP use cases in a pilot.

5. Microsoft Entra Internet Access: best for Microsoft 365-first teams

Entra Internet Access is Microsoft's identity-centric secure web gateway, built into Entra ID. It applies Conditional Access to internet traffic, adds web-category and FQDN filtering, and uses universal tenant restrictions to curb data exfiltration, so admins don't manage users and apps in a separate tool (Petri). It fits Microsoft 365- and Entra-heavy organizations that want web security managed alongside identity. Watch for: coverage is strongest inside Microsoft's ecosystem, AI prompt controls require TLS inspection to be on, and the product is younger than dedicated SSE platforms. See What is Microsoft Entra Internet Access?

6. Cato Networks: best if you're replacing MPLS too

Cato runs SD-WAN and security on its own private global backbone, managed from one console. In Gartner's 2026 SASE Platforms Magic Quadrant it moved up to second place among the four Leaders, with Gartner citing above-average customer experience and planned shadow-AI and agentic-threat controls, aided by its Aim Security acquisition (SDxCentral). It fits mid-to-large enterprises replacing MPLS and SSE in one move. Watch for: it's a networking project as much as a security one, and inspection still happens in a Cato PoP. See What is Cato Networks?

7. Fortinet FortiSASE: best for Fortinet estates

FortiSASE extends FortiGate policy to remote users. Gartner named Fortinet a Challenger in the 2025 SSE Magic Quadrant, and coverage notes that FortiSASE runs on Fortinet's single FortiOS operating system with one console, endpoint agent and data lake, plus integrated SD-WAN, per Fortinet (TelcoNews). It fits teams that already run FortiGate firewalls and want SSE to reuse their policy objects and operations staff. Watch for: value is highest inside the Fortinet fabric; outside it, you're evaluating a Challenger-placed SSE on its own merits. See What is FortiSASE?

8. Forcepoint ONE: best for DLP-led buyers

Forcepoint brings a long data-protection heritage to SSE, combining DLP, CASB, SWG, and ZTNA in one data-security-centric platform. As of October 2026 it's rated 4.2/5 on G2 across 103 reviews, where it's now listed as Forcepoint Data Security Cloud in the DLP, CASB, SSE, and SASE categories (G2). It fits buyers for whom data protection is the reason for the project and who want classification at the center of policy. Watch for: policy-driven DLP takes tuning to keep false positives down, so budget analyst time after rollout. See What is Forcepoint?

9. Cisco Secure Access: best for Cisco-standardized teams

Cisco Secure Access is Cisco's SSE platform and the destination for Umbrella customers, now that Umbrella SIG and DNS reach end of sale on January 31, 2027. In Gartner's 2026 SASE Platforms Magic Quadrant, Cisco was placed as a Challenger and credited for its PoP infrastructure and sales execution (SDxCentral). It fits teams standardized on Cisco networking that want SSE from the same vendor. Watch for: the same report noted management complexity, and moving SWG and private access from Umbrella to Secure Access isn't a one-click upgrade, so it's worth comparing against other options.

How long does it take to replace Zscaler?

With a cloud-proxy alternative, plan for a re-architecture: new tunnels, new forwarding profiles, new connectors, and a parallel run. With dope.security, there's nothing to forward. Push the agent through your MDM (Intune, Jamf, and the like), confirm policies, and expand. A practical plan:

• Week 1: Start a free trial with Google or Microsoft SSO and deploy to 25 pilot endpoints next to ZIA.
• Weeks 2 to 3: Mirror URL policy, turn on Cloud Application Control for AI tools, and run Dopamine DLP in monitor mode.
• Week 4: Expand fleet-wide and turn off ZIA forwarding.

FAQ

What is the best Zscaler alternative for 2026?

It depends on why you're leaving:

• Latency, data residency, or decryption privacy: dope.security, which inspects on the device and sends traffic direct, with no built-in ZTNA today.
• You want to stay on a cloud proxy with deeper CASB: Netskope is the closest like-for-like option.
• You're replacing MPLS at the same time: Cato Networks.
• You're standardized on one ecosystem: Palo Alto, Microsoft, Fortinet, or Cisco usually make the most sense.

Can I replace ZIA without replacing ZPA?

Yes. Many teams replace ZIA first and keep ZPA or another ZTNA tool for private apps through the next renewal. Check your contract, since bundles can change the math. Background: Zscaler ZIA vs. ZPA.

How much does Zscaler cost compared to alternatives?

Zscaler doesn't publish list prices. Pricing depends on edition, user count, and add-ons. Our Zscaler pricing guide breaks down what drives the quote. dope.security publishes pricing on its website.

Which Zscaler alternative is best for governing ChatGPT and Claude?

Look for three layers: discovery of which AI apps are in use, tenant-level control (corporate account allowed, personal blocked), and DLP that reads prompts and uploads. Several vendors on this list address these layers in their clouds; dope.security does all three on the device with AI Analytics, Cloud Application Control, and Dopamine DLP.
