GlassWire: A Visual Layer Between You and the Network What Is It? GlassWire isn’t a firewall replacement, and it’s not trying to be. What it does — and does well — is give users a clear, visual timeline of how their system is using the network. It shows when things connect, what connects, and how much traffic is moving — all in a smooth, timeline-based UI.

It’s not trying to outgun antivirus software. Instead, it digs where AVs often don’t bother: browser hijackers, leftover adware, sketchy registry edits, and privacy-invasive trackers.
