CallerIP monitors activity on open ports, which are often not protected by firewalls, on your computer so you can identify hackers before damage is done. A click on a connecting IP address shows where the connection originates on a world map, along with the necessary domain and network registration details -- including abuse-reporting information -- so you can report the intruder to the authorities. CallerIP scans the ports on your system and alerts you to active and open 'backdoors' which can provide unauthorized access to launch harmful attacks or steal confidential information. CallerIP Professional includes automated alarms for instant notification of suspect connections, the ability to plot all connections on a world map, and a server option to monitor connections to a remote system.
