While NetResident is similar to network analyzers in many respects, it focuses on high-level protocols that are used to transfer content over the Internet or LAN. With NetResident, you don't need a profound understanding of networking technologies, have to use complex packet capturing and analysis software, or dig through network packets trying to reconstruct the actual data; NetResident does all the work for you and presents only the Web pages, e-mail messages, or downloaded files as requested.
NetResident is used by network administrators to enforce IT policy, by parents to monitor their children’s communication on the Internet, and also by forensic experts to gain important information.
