What it does
GlassWire visualizes network activity, application connections and data usage, with alerts and connection-control features.
Use GlassWire’s graph and time-machine view to see which applications and hosts were active during a traffic spike. Usage breakdowns and first-activity alerts help identify what to investigate, while connection controls depend on the selected edition. The pricing comparison lists 24 hours of network history, one day of bandwidth-usage monitoring and current-day alert logs for Free, with expanded history and additional controls in Premium. Check that window before expecting to investigate an older event. The PC and Android products have different feature scopes. A graph or an unfamiliar remote address provides investigation context; it does not by itself establish that an application is malicious.
