The excellent free Windows network monitor GlassWire is now also available in Basic ($49), Pro ($99) and Elite ($199) versions.

All three builds have extra security features. “Ask to connect” blocks new network connections until they’re approved by you; “Lock down mode” blocks everything until you turn it off; a wifi monitor lists everything on your network and alerts you when devices join or leave.

The Alerts pane now also warns you when your webcam or microphone is accessed, and lets you know which application is responsible.

The commercial builds can now monitor network traffic for up to 10 computers

Interface options include new skins, and a “Mini graph”, a desktop gadget with a small view of network activity.

There’s now support for “remote connections”, enabling you to monitor the activity on multiple remote connections (Basic: 3, Pro: 10, Elite: Unlimited).

The individual versions also support different network history (Free: 1 month, Basic: 6 months, Pro: Unlimited) and are licensed for more PCs (Basic: 1, Pro: 3, Elite: 5).

But if you’re an existing user, don’t worry, the good news is that the free version of GlassWire is still available, and it’s not been hobbled or restricted in any way.
