GlassWire vs ZoneAlarm
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.
ZoneAlarm is a long-running personal security brand now owned by Check Point Software Technologies, built around a two-way firewall that inspects both inbound and outbound traffic. It pairs that firewall with real-time antivirus and anti-spyware scanning, anti-phishing protection, and threat emulation aimed at catching zero-day threats before they execute. The product line ranges from a free firewall and free antivirus up through paid tiers like ZoneAlarm Pro Antivirus + Firewall and ZoneAlarm Extreme Security NextGen, which adds ransomware protection and broader coverage. Apps are available for Windows, Mac, Android, and iOS, and the suite has picked up awards such as PCMag Editors' Choice and AV-Test certifications over the years.
