Use GlassWire's simple to use interface to view all your past and present network activity on a graph. Click the graph to see what applications initiated the incoming or outgoing bandwidth and instantly see what hosts the applications were communicating with. Hosts are automatically resolved and also include their country of origin. Click the Apps and Traffic options to break down network activity by applications and traffic types.

Internet Security
GlassWire adds extra Internet security to your computer or server by visualizing all past and present network data in an easy to understand graph. Instantly see every application or process communicating over the Internet, then dive in deeper to see who or what your computer is communicating with. Whenever anything new on your computer accesses the network GlassWire lets you know with a discreet alert that won't interrupt your workflow or server.
GlassWire also has a toolbox of network security checks like system file change detection, device list change detection, app info change detection, ARP spoofing monitoring, and we're just getting started. Our software also alerts you if your computer or server is communicating with a known IP or domain threat. We're working hard on adding many more intrusion detection rules to GlassWire in the future.
Unfortunately comprehensive malware detection and perfect network intrusion detection does not exist. Our software isn't perfect but we hope that GlassWire's mix of easy to use network visualization, firewall management, and network monitoring rules will do good in the never ending war against spyware and malware. GlassWire's Internet Security is a second line of defense and should always be used with a separate primary antivirus product.

GlassWire is an easy to use tool that can see your past and present network activity. Use the sliders to go back in time and analyze past network activity on the graph. Check your bandwidth usage by day, week, and month in detail with resolved hosts.
Go to the graph or alerts tab to see exactly when an app first accessed the Internet and what hosts it communicated with along with any available geoip country information represented by a small flag. Check the graph for past security alerts along with detailed host information.
It's easy to see past network activity with GlassWire along with detailed network activity on a simple to understand graph.
GlassWire Snooze
Discreet Alerts
We specifically designed the GlassWire alert system so it wasn't annoying to users. It's important to see what network changes are happening on your computer or server but constant pop-ups that need to be closed are frustrating. If you're doing a screencast or don't want any alerts at all for a set period go to the GlassWire menu and choose “snooze” to stop receiving alerts for 24 hours. We understand that in some cases alerts from software can be very annoying. GlassWire alerts appear briefly and then disappear into the background. You can go to the GlassWire alerts tab or check the graph any time later to check out the alert in detail. If you don't like alerts at all you can disable our security alerts in the settings, or just disable our alerts in the main settings window. If security alerts aren't your thing you can disable them all and just use GlassWire as a network monitor, however we don't recommend this.
Bandwidth Usage Monitor

Bandwidth Usage
Monitor

Keeping track of your daily, weekly, or monthly bandwidth usage is easy with GlassWire. Go to the usage tab to see what apps, traffic, or hosts are using the most bandwidth. See something strange? Click the icon of the app or traffic type to see more details about where your bandwidth was going along with any available geoip country ip information.
Please keep in mind that GlassWire only keeps track of bandwidth for the computer and server it's installed on and not total bandwidth usage on your network.

GlassWire Remote Server Monitor

Remote Server
Monitoring

Do you monitor remote servers for business, gaming, VOIP applications, or web applications? GlassWire installs easily on servers so you can monitor their network activity on your local computer via our remote access feature. Go to GlassWire's settings and choose “remote server” to logon to your server after you have installed GlassWire on your local computer and remote server.
GlassWire works exactly the same way on a remote server as it does on your local computer. See security alerts, new app network activity, and much more!

Internet Privacy
Protection

GlassWire shows all your network activity on an easy to use graph to help protect your Internet privacy. Easily see what apps are sending out data to the Internet and what host in what country they are communicating with. When you visit a website click the graph to see every server that your computer communicated with while that web page loaded. Visit a popular website with GlassWire running and you'll be shocked to see how many different hosts are communicating with your computer for just one site.
Every time a new application accesses the Internet GlassWire will alert you. You can then use GlassWire's firewall to block the application.
GlassWire's graph also shows when your computer is in use or idle. Keep track of major network activity when you were away from your computer and try to find out if that means something is wrong or if it's normal behavior.
