Cloudflare One Client is a Windows connectivity agent that links devices to Cloudflare for managed internet filtering, device health checks, and authorized access to an organization’s private applications.
Cloudflare One Client connects Windows devices to Cloudflare’s network so organizations can apply internet security policies and provide access to private applications. Formerly called WARP, the client combines encrypted connectivity with device information that administrators can use when deciding who may reach protected resources. Employees enroll their computers in an organization, then work through the connection settings and policies assigned to them. Its main role is to extend centrally managed protection to devices outside the office, including people working from home or travelling. Available inspection and access capabilities depend on the selected operating mode, account services, and administrator configuration.
Cloudflare One Client requires deliberate configuration because its operating mode determines which traffic and security signals reach Cloudflare. Readers comparing personal browsing protection with managed workplace access may also consider Proton VPN when evaluating different connection models. Traffic and DNS mode handles both network traffic and name resolution, while DNS-only mode leaves application traffic on its normal route. Administrators can also select modes intended for existing DNS infrastructure or device checks without tunneling. Private resources require configured connectivity on the organization’s side. Installing the application alone does not create access permissions, publish internal services, or automatically enable every inspection feature.
Cloudflare One Client can reduce the effort of supporting secure work across office and remote locations by giving administrators a consistent endpoint connection to manage. Teams can define how enrolled devices connect instead of asking employees to reproduce network settings for each application or location. This makes onboarding more repeatable and gives support staff a clearer starting point when investigating access problems. Device health signals also let organizations tie resource access to practical requirements, such as encryption or an acceptable operating system version. For employees, correctly configured private routing means internal tools can remain part of their normal workflow without being opened to the public internet. Different operating modes allow staged deployments around existing infrastructure, which can reduce the disruption of adopting new controls. These benefits depend on accurate policies, enrollment, and testing; the client supplies the connection and device signals, while the organization determines the protection and access outcomes.
Key capabilities and highlights.
Cloudflare One Client establishes an encrypted connection from the endpoint to Cloudflare’s network for traffic routed through the tunnel. This provides the transport used by organization-managed security services and private access. The scope of that connection depends on the chosen mode and routing rules, so administrators should verify what is actually included.
DNS-only mode forwards name resolution to the Cloudflare account resolver while leaving ordinary application traffic on its existing network path. Organizations can apply DNS filtering without deploying full traffic inspection at the same time. This mode is useful for a narrower rollout, but it does not provide network or HTTP filtering.
Cloudflare One Client can send device traffic to Gateway, where configured DNS, network, and HTTP policies determine how requests are handled. In Traffic and DNS mode, this supports a broader set of controls than DNS filtering alone. Inspection capabilities depend on the organization’s setup, including certificates where required for encrypted web inspection.
The client reports device properties that Access and Gateway policies can evaluate before allowing protected activity. Supported Windows checks include operating system version, disk encryption, antivirus, and firewall status. Cloudflare One Client supplies these signals, while administrators define acceptable results and the policies that use them to make access decisions.
Enrolled devices can reach internal networks and applications through configured Cloudflare connectivity, including Cloudflare Tunnel. This lets organizations provide access without making those resources publicly reachable. Routes, user permissions, and relevant policies still need to be configured; installing the endpoint client is only one part of a working private-access deployment.
Cloudflare One Client offers Traffic only, Local proxy, and Posture only modes for deployments with different requirements. Traffic only retains operating-system DNS handling; Local proxy accepts explicitly directed application traffic; Posture only collects device signals without forwarding traffic or DNS. Administrators can choose a mode that fits existing network and security tools.
Managed networks let administrators apply particular device profiles when a computer connects to a recognized location, such as an office. This allows connection behavior to reflect the network environment instead of relying on employees to change settings manually. Cloudflare One Client uses the organization’s configured detection and profile rules to determine the applicable setup.
Organizations can distribute the client and its configuration through supported device-management tools, making installation and enrollment more repeatable across Windows computers. Cloudflare One Client supports deployment parameters for managed settings. Administrators should account for configuration precedence, because settings supplied through device management can override corresponding dashboard profile choices on the endpoint.

Common questions about Cloudflare One Client.
It is the renamed WARP client in Cloudflare’s organizational documentation. Consumer WARP and organization-enrolled use have different purposes and configurations; joining an organization enables its assigned policies and services.
The proprietary client works with Cloudflare services that offer free and paid plans. Available organizational features, limits, and support depend on the selected plan; downloading the application does not include every paid service.
Cloudflare lists Windows 10 LTSC, Windows 11, and Windows 365 Cloud PC running Windows 11. The client requires .NET Framework 4.7.2 or later. This download targets x64; Cloudflare also documents ARM64 support.
Cloudflare identifies the release as 2026.7.1376.0. It fixes invalid registrations that could prevent connections or organization switching after changing installed versions, and addresses intermittent DNS query failures.
No. It forwards DNS resolution to Cloudflare but leaves application traffic on the device’s ordinary network path. Use the appropriate traffic-routing mode when the deployment requires traffic to pass through Cloudflare.
