About this app

CGuard helps you understand and protect the networks around you. Scan nearby WiFi networks, identify suspicious access points and common network threats,
review risk details, and use security tools to investigate URLs, ports, and
vulnerabilities.

Features include:
- WiFi network scanning and security analysis
- Detection of suspicious networks and threat indicators
- Scan history and risk details
- Security tools for URL, port, and vulnerability checks
- Secure account, device, and notification management
- WireGuard VPN connections to available CGuard servers

### Why CGuard uses Android VpnService

CGuard uses Android's `VpnService` API to provide its optional WireGuard VPN feature. When you choose a CGuard server and approve Android's VPN permission prompt, the app creates an encrypted WireGuard tunnel and routes device network traffic through that selected CGuard server. This helps protect network traffic when using untrusted or high-risk WiFi networks.

You control when the VPN is connected and can disconnect it from the CGuard VPN screen. After a WiFi security scan identifies a high-risk network, CGuard may recommend or automatically start the VPN according to the app's risk protection flow. Android displays the active VPN indicator while the tunnel is running. The VPN feature requires an eligible CGuard plan and an available server.

The VPN is not required to use the WiFi scanner or the other security tools.
You must explicitly approve Android's system VPN permission before CGuard can start a VPN connection.

By installing CGuard, you agree to the applicable terms and privacy policy.
