GlassWire for Windows

Identify malware and suspicious network behavior

GlassWire is a security and privacy utility that reveals both current and historic network traffic so you can spot malware, spyware, and other hidden threats. It notifies you when network-related components change or when an application behaves unusually, and it lets you block connections that look risky. The app is available for free download, with optional paid upgrades (Basic, Pro, and Elite) that unlock additional capabilities. Recommended alternative: Privatefirewall (free).

Key capabilities and how they help

• Visual network timeline: An easy-to-read graph shows what your PC has been doing online, making it simple to compare present and past activity.
• Threat alerts: Real-time notifications warn you about suspicious network events so you can respond quickly.
• Firewall management: Tools to monitor and control which apps can access the internet and to block unwanted connections.
• Remote monitoring: Keep an eye on servers or external hosts your system communicates with.

Interface tweaks and extras

• Compact viewer: A small “mini” window you can enable to monitor traffic while working, with adjustable size and transparency.
• Appearance options: Customize the look of the traffic graph by choosing color schemes and skins.
• Language support: Multiple localization choices are available so the interface can match your preferred language.
• Bandwidth control: Identify and disable programs that are consuming excessive bandwidth to improve overall connection speed.

Take charge of your network and privacy

Using GlassWire gives you greater visibility into what programs and services are doing on your network. The visual data helps you decide which apps to block or uninstall, and the proactive alerts can help you stop malicious activity before it leads to a data breach. With the combination of monitoring, firewall controls, and customization, you can build extra layers of protection around your system and preserve your privacy.
