GlassWire vs TeamViewer

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.

TeamViewer is a cross‑platform remote‑desktop solution that lets users connect to computers, smartphones, and servers for support, administration, and collaboration. It offers encrypted connections, file transfer, and session recording without requiring VPN or firewall changes. The service provides a free tier for personal use and paid subscriptions for businesses, adding features like multi‑user sessions, mass deployment, and advanced reporting. TeamViewer integrates with ticketing systems and supports mobile devices, making it a versatile tool for IT teams and remote workers.
