GlassWire vs VMware vRealize Network Insight
Side-by-side comparison of features, pricing, ratings, and alternatives.
GlassWire is a network monitoring and personal firewall application for Windows and Android that visualizes current and past network activity to help users spot malware, bandwidth hogs, and unfamiliar devices on their network. Its firewall includes an ask-to-connect mode that lets users approve or deny individual apps' network access, alongside a network time machine for reviewing historical connections. GlassWire also tracks data usage across devices and can alert users before they exceed set data limits, while its network scanner flags new or unknown devices joining a WiFi network. Over 53 million downloads have been recorded for the Windows and Android apps combined.
