TupSight

TupSight is a sniffing program that will make direct and reliable web monitoring.
Unlike many other packet sniffing programs that use WinPcap library (www.winpcap.org) as the driver to capture live network data, TupSight is an NAT router technology-based EIM (Employee Internet Management) product realizing direct and reliable web monitoring and control at the Internet gateway.
TupSight can be installed on one of the computer hosts on any LAN
infrastructures (i.e., no mater they are switched or wireless); and is NIC (network interface card)-independent (for example, it works with such as a gigabit network adapter that is usually not compatible with WinPcap).
TupSight not only logs in real time URL visits, Email, chats, games, FTP, and data flows, but also takes webpage snapshots, duplicates Email and FTP copies, records MSN messenger content, and gives statistical reports. It freely restricts online activities with preset time schedules and according to customized filtering Internet policies.
As an NAT router by nature, TupSight provides DNS forwarding and proxy functions and shares a single Internet connection to all computer hosts on a LAN. It also supports port mapping for reverse proxy services so as to provide Web-based applications to the Internet.
TupSight is also equipped with an easy-to-use and reliable switch sniffer to suit the needs of the "Tech Dummies."Limitations in the unregistered version15 days trial
