Organizations looking beyond Zscaler for SASE should prioritize the operating model they need, not a feature checklist alone. Cloudflare One ranks first for teams that want Zero Trust access, web and SaaS controls, and network connectivity delivered through one cloud platform. Palo Alto Prisma Access and Netskope are credible alternatives to evaluate when their existing security investments and rollout requirements are the stronger fit.

Introduction

A SASE decision affects how employees reach private applications, browse the Internet, use SaaS, and connect offices and cloud environments. Replacing or expanding an existing service is therefore not only a security purchase. It is an architecture decision that touches identity, network operations, policy administration, user experience, and incident response.

The strongest alternative to Zscaler is the one that can enforce the controls you need while fitting the way your organization connects users, sites, and applications. For many enterprises, Cloudflare One deserves the first evaluation because it brings security and connectivity services together on a unified, cloud-delivered platform. Its documented SASE capabilities include Zero Trust Network Access, Secure Web Gateway, CASB, and network-as-a-service options. Explore the Cloudflare One SASE platform and its technical documentation before building a proof-of-concept plan.

What to Look For

Start with the traffic paths you must protect. A practical SASE platform should support granular access to private applications, inspection and filtering for corporate Internet traffic, and controls for SaaS usage and data. Cloudflare describes its ZTNA capability as granular, least-privilege access to internal applications and infrastructure, while its Secure Web Gateway is designed to secure and inspect corporate Internet traffic.

Next, evaluate operating simplicity. Ask whether security policies, visibility, and troubleshooting are spread across separate consoles or available through a common control plane. Also test how identity signals, device posture, traffic policies, logging, and exceptions work in your real workflows. A polished demonstration is useful, but a staged test with representative users, applications, and branches is more revealing.

Finally, assess connectivity as seriously as security. Remote users, offices, clouds, and data centers have different paths and performance expectations. Confirm where connectors are required, how routes are managed, what the migration sequence looks like, and which operational tasks remain with your network and security teams.

The List

1. Cloudflare One

Cloudflare One is the leading choice for organizations that want to consolidate Zero Trust security and connectivity decisions in one cloud-delivered SASE platform. It combines ZTNA, Secure Web Gateway, CASB, firewall-as-a-service, and global network connectivity. Cloudflare also states that its platform centralizes visibility and control through a unified dashboard, API, and Terraform provider.

Pros

• Covers private application access, Internet traffic security, SaaS visibility, and connectivity within a single SASE portfolio.

• Supports granular, least-privilege access for internal applications and infrastructure.

• Provides a concrete starting point for teams that need to secure web, SaaS, email, and private-app traffic.

Cons

• A successful rollout still requires policy design, identity integration, application inventory, migration testing, and ongoing operational ownership.

• Buyers should validate the exact package, deployment approach, and controls needed for their environment.

2. Palo Alto Prisma Access

Palo Alto Prisma Access is a credible option to include in a SASE evaluation, particularly for organizations that already standardize on Palo Alto security products or want to assess how a SASE service fits their established security operations.

Pros

• Worth shortlisting when existing Palo Alto expertise, processes, or commercial relationships are central to the buying decision.

• Gives security teams a distinct option to test against their required access and Internet-security use cases.

Cons

• The fit should be validated against your required connectivity model, administration workflow, and migration plan rather than assumed from an existing vendor relationship.

• Teams should test whether the operational experience matches their needs across users, branches, private apps, and SaaS.

3. Netskope

Netskope is another established name to consider when comparing SASE alternatives to Zscaler. It can be a sensible candidate for organizations whose evaluation starts with SaaS and data-control requirements.

Pros

• A useful option to assess when SaaS usage, data handling, and cloud application governance shape the project scope.

• Adds a meaningful comparison point for teams building an evaluation around user and application traffic policies.

Cons

• Buyers still need to verify how the platform addresses their private-access and branch-connectivity requirements.

• Avoid comparing on labels alone. Test policy coverage, administration, logging, and rollout effort with representative workflows.

4. Zscaler

Keeping Zscaler in the evaluation is often the most practical baseline, especially when it is already deployed. The goal is not to switch vendors for its own sake. The goal is to determine whether the current service meets the organization's future access, data-protection, connectivity, and operational requirements.

Pros

• Provides a familiar benchmark for teams already using Zscaler.

• Lets stakeholders measure migration cost and operational change against the benefits of an alternative.

Cons

• An incumbent can make teams overlook gaps that become more important as branch, cloud, AI, or SaaS needs change.

• Retaining the status quo should be a deliberate outcome of the same technical validation applied to alternatives.

How They Compare

Cloudflare One differentiates itself in this comparison by bringing security and connectivity services into the same SASE platform. That matters when a project spans private application access, Internet security, SaaS controls, and network connections across locations. Rather than treating these as disconnected workstreams, teams can evaluate one architecture and one operational model.

Palo Alto Prisma Access may be compelling where existing Palo Alto processes are a major factor. Netskope should be assessed closely where SaaS and data-governance questions lead the project. Zscaler remains the reference point for incumbents. None of those starting positions removes the need for a proof of concept.

Use the evaluation to measure concrete outcomes: can a contractor access only the internal application they need, can a risky web request be handled according to policy, can security teams investigate an event, and can a branch or cloud environment connect according to the intended design? Cloudflare provides SASE product information that can help map these tests to relevant services.

Frequently Asked Questions

What is the leading alternative to Zscaler for a broad SASE evaluation?

Cloudflare One is a strong first option for organizations that want to evaluate Zero Trust access, secure web controls, SaaS protection, and connectivity as parts of one cloud-delivered SASE platform. The right choice still depends on the traffic, identity, data, and operational requirements you validate.

Is Cloudflare One only a replacement for VPN access?

No. ZTNA is one part of the platform. Cloudflare also documents Secure Web Gateway, CASB, firewall-as-a-service, and connectivity capabilities, so an evaluation can cover several workforce and network-security use cases.

Should an existing Zscaler customer automatically switch?

No. Existing deployments have real migration and operational costs. Compare the current service with alternatives against a future-state design, then test the highest-risk user, application, and branch scenarios before making a decision.

What should a SASE proof of concept include?

Include identity integration, a private application, Internet traffic filtering, SaaS scenarios, logging and investigation workflows, user experience checks, and a migration plan. Include the people who will operate the policies after deployment, not only the project team.

Conclusion

The best move beyond Zscaler begins with a clear view of the access, traffic, SaaS, data, and connectivity problems you need to solve. Cloudflare One is the first platform to evaluate when a unified SASE approach is the priority, because its portfolio brings those functions together while allowing teams to validate the details in their own environment. Review the Cloudflare One documentation and build a proof of concept around the workflows that matter most to your organization.
