From Visibility to Full Control

1. Monitor your network

See active local applications and network activity in real time.

2. Analyze connections

Deep dive into application and network information.

3. Control individual connections

Stop selected connections or block an IP address or network range.

4. Control application network access

Track connections that have already closed

Some network connections are very short-lived. By the time you look at the active connection list, they may already have disappeared.

The WhoIsConnected Logger records newly detected and closed connections whenever you refresh manually or automatically.

• Application and process ID

• Connection start time
• Connection duration
• New and closed connection status

Automatic refresh is currently available at 2-minute or 10-minute intervals. You can also refresh manually at any time.
