Open Network Connections with DNS Names
Shows active TCP/IP connections with owning process name, remote DNS name and remote port, allowing you to filter by any of these parameters.


Check open network connections instead of running a command to check for open ports in Windows of each endpoint you have. Shows all active IP connections with all relevant details, such as destination IP address and DNS name for that IP address (if available). Use this free tool instead of Windows Network Monitor or PowerShell scripts (Get-NetTCPConnection cmdlet) to understand TCP/IP statistics, monitor TCP connections on Windows endpoints and create alerts when connections to certain hosts are established.

Sign-up for Action1 Free Edition to install/uninstall software and patches, receive real-time alerts and view instant data from your endpoints, or run live or scheduled queries with the ability to export to CSV or Excel. Action1 Endpoint Security Platform is entirely SaaS, with online web interface (no management tools to install) and it has zero cost for basic functionality. Running in the Cloud, Action1 discovers all of your endpoints in seconds and you can query your entire network in plain English.
