PortsLock®

PortsLock® is an endpoint security solution that allows system administrators to specify network policy rules based on user and group membership.

It provides user-level network policy restrictions for Windows workstations and servers. Once PortsLock® is installed, administrators can assign permissions to TCP/IP connections, just as they would in managing permissions on an NTFS partition of a hard disk. It lets you control which users or groups can access what TCP/IP based protocols (HTTP, FTP, SMTP, POP3, Telnet, etc.) on a local computer, depending on the time of day and day of the week. You can also set allowed/denied TCP/UDP ports and IP addresses for incoming and outgoing connections on a per-user basis.
