GlassWire vs Observium
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.
Observium is a network monitoring platform that automatically discovers devices and services on a network and collects real-time and historical performance data, presenting it through a web-based dashboard. It supports over 450 device operating systems and vendors, including Cisco, Juniper, HP, Dell, Windows, and Linux, and provides threshold, state, and syslog-based alerting. Beyond monitoring, Observium includes traffic accounting and billing features, rule-based automatic device grouping, network mapping, and a RESTful API for integrating with other tools. It ships in a free Community edition, alongside paid Professional and Enterprise editions that add real-time SVN updates and support hours, and is used by organizations including Twitch, eBay, and Spotify.
