GlassWire vs Paessler PRTG Network Monitor

GlassWire is a network traffic monitor and personal firewall for viewing network activity and controlling app connections. Its desktop traffic analysis breaks usage down by IP or host, app, traffic type, and other categories. Alerts flag unusual network or app changes that could indicate malware and unknown devices joining Wi-Fi. The Android app graphs app data use, alerts when apps access the network, and can block connections over mobile or Wi-Fi. GlassWire says Android app and data usage information stays on the phone and the app itself uses no data. The free tier limits network history to 24 hours, bandwidth usage history to one day, and alert logs to the current day. Premium provides unlimited network history, bandwidth history, and alert logs, along with bidirectional firewall controls, custom profiles, Ask to Connect, and Lockdown Mode. The Personal Plan costs $2.99 per month when billed annually. The desktop download requires Windows 10 or later and supports x64 and ARM64 architectures.

Paessler PRTG Network Monitor monitors systems, devices, network traffic, applications, and other infrastructure metrics from an on-premises installation. It runs on Windows servers and includes more than 250 preconfigured sensors, each measuring one or more aspects of a device. Monitoring tools include customizable alerts, scheduled reports, distributed monitoring, and dashboards with live status information. Paessler also lists adaptive AI-driven anomaly detection and smart sensor recommendations. PRTG provides an API for monitoring data and custom features, and can send webhook notifications to Slack and Microsoft Teams. Its free iOS and Android apps display monitoring data and send push notifications, but do not support cluster setups. The free plan covers up to 100 sensors; paid plans start at $200 per month paid annually. Each server accepts one license key, so license sizes cannot be combined on a server.
