## WARP traffic flow

1717
The WARP client allows organizations to have granular control over the applications an end user device can access. The client forwards DNS and network traffic from the device to Cloudflare's global network, where Zero Trust policies are applied in the cloud. On all operating systems, the WARP daemon maintains three connections between the device and Cloudflare:

## How WARP works
1616

17-
WARP is a lightweight device client, which builds proxy tunnels using either Wireguard or MASQUE, and builds a DNS proxy using DNS-over-HTTPS. WARP supports all major operating systems, all common forms of endpoint management tooling, and has a robust series of management parameters and profiles to accurately scope the needs of a diverse user base.

- WARP daemon (or service): Core background component responsible for establishing secure tunnels (using technologies like WireGuard or MASQUE) and managing all interactions with Cloudflare's network. It ensures traffic is securely directed and policies are enforced.

- **Device posture checks**: The WARP client provides advanced Zero Trust protection by making it possible to check for [device posture](/cloudflare-one/identity/devices/). By setting up device posture checks, you can build Zero Trust policies that check for a device's location, disk encryption status, OS version, and more.

## WARP modes

4545
WARP offers flexible [operating modes](/cloudflare-one/connections/connect-devices/warp/configure-warp/warp-modes/) to suit your specific needs. WARP can control device traffic as a full proxy, manage only DNS traffic as a DNS proxy, or both. WARP is the most common method for sending user device traffic through Cloudflare Gateway for filtering and decryption.
