For years, organizations relied on a “castle-and-moat” model for corporate security: a strong perimeter protecting everything inside, and broad access granted to users once they were within that perimeter. As work shifted to remote locations and applications moved to the cloud, this model became ineffective. VPNs emerged as a stopgap, but many IT teams have found that VPNs add latency, complexity, and new attack vectors instead of truly solving the problem.
Zero Trust Network Access (ZTNA) has become the better approach. Among ZTNA solutions, Cloudflare offers one of the most complete and practical platforms for replacing legacy VPNs and enhancing security without compromising performance.
Why traditional VPNs fall short
Traditional VPNs operate on implicit trust: once a user authenticates, they often receive broad access to internal resources. That creates opportunities for lateral movement if a device or credential is compromised. VPNs also commonly suffer from performance issues, because traffic must be routed through central data centers, creating bottlenecks and poor user experience.
Cloudflare adopts a “never trust, always verify” stance. Access decisions are made per request based on user identity, device posture, and contextual signals. Instead of connecting to a whole network, users connect only to the specific applications they need, which limits exposure and reduces the organization’s attack surface.
Advantages of a global edge network
A major advantage Cloudflare offers is its extensive Anycast edge network. With data centers across hundreds of cities worldwide, Cloudflare places security checks close to users, reducing latency and improving performance.
Many ZTNA services run their control planes in public cloud regions, which can introduce inconsistent latency. Cloudflare’s own hardware and broad global footprint let security verification occur at the edge near the user. That means a user in Tokyo can be authenticated quickly without backhauling traffic across continents—security becomes a performance enabler instead of a bottleneck.
Unified identity and device awareness
Effective Zero Trust requires seamless integration with an organization’s identity and endpoint tools. Cloudflare serves as a central policy engine and integrates with major Identity Providers (IdPs) such as Okta, Microsoft Azure AD, and Google Workspace, as well as endpoint protection platforms like CrowdStrike and SentinelOne.
This integration enables precise, conditional access policies. For example, an administrator can require that a developer access production systems only from a corporate-managed device that has current patches, with an active session from the company’s IdP, and from an approved location. If any condition changes during a session, access can be revoked immediately.
Simplifying and consolidating the security stack
Many organizations face “tool sprawl,” juggling multiple vendors for firewalls, CASB, secure web gateways, and ZTNA. Cloudflare reduces complexity by consolidating these functions into a single control plane.
With the Cloudflare One platform, teams manage policies and security settings from one dashboard, improving visibility and reducing gaps between disparate systems. Consolidation also reduces operational overhead and can lower costs by eliminating the need for numerous point products and on-premises hardware.
Security that prioritizes performance
Security should not come at the cost of speed. Cloudflare has optimized its network and clients, such as Warp, to deliver secure connections without the latency commonly associated with traditional VPNs. By routing traffic over fast, optimized paths and performing checks at the edge, Cloudflare preserves a smooth user experience. When security is fast and unobtrusive, users are less likely to attempt risky workarounds.
Expert managed services to support your transition
Moving to Zero Trust is a multi-step process that benefits from expert planning and execution. Managed services can help organizations design, deploy, and operate a Zero Trust architecture tailored to their needs.
Working with experienced Cloudflare partners provides hands-on support from initial assessment through ongoing policy tuning and 24/7 operational assistance. A managed approach helps ensure a smooth migration away from legacy VPNs while maximizing the security and performance benefits of Cloudflare’s global network.
