What Windows Guardian does

Guardian helps you inspect your PC’s network activity and available protective settings.

Connection monitoring

View connections, remote addresses, network traffic and reported suspicious events. Monitoring is available when the relevant Guardian component is active.

Protected DNS

Review and adjust available DNS provider settings, including filtering options where supported. A DNS filter can block known malicious domains but not all threats.

Botnet-address checks and alerts

Review warnings and events linked to suspicious or known botnet addresses. A warning is not proof that a connection has been blocked; blocking depends on the installed implementation and settings.

Guardian is not a replacement for your Windows firewall or antivirus. Continuous monitoring and automatic blocking must not be assumed when the app is closed.
