Automatically scan your network
Do you know for sure how many PC's are connected to your network? Whether you're a network administrator or home user, AutoScan Network will allow you to see instantly who and who is not connected to your network.
AutoScan features fast multithreaded scanning, automatic network discovery and entire subnets can be scanned simultaneously without human intervention. You can monitor equipment such as routers (useful for home users) plus servers and firewalls (excellent for network administrators). Alternatively, you can monitor network services such as SMTP, HTTP and POP.
AutoScan Network can also detect the OS of connected computers, brand and even the model. Possibly the most useful function is an "Intrusion Alert" which means that if you activate it, any new connecting equipment will immediately trigger an alarm - superb if you are trying to protect your wifi network.
As far as protecting networks go, this is a very basic but effective tool probably of most interest and use for home users.
