Portslock for Windows NT / 2000 / XP

PortsLock is a firewall
with user-level access controls for Windows NT/2000/XP. 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 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.

PortsLock is absolutely transparent to users. Users do not have to set up
rules in their applications to use the network. Only administrators are allowed
to set rules so users without administrative privileges cannot bypass the
PortsLock security. It is important to note that PortsLock works perfectly with
other personal firewalls and routers installed on the same computer.

With PortsLock you can:

  • Block access to network resources (web sites, network services, LAN, etc.)
    for a particular user or user group
  • Control access to network resources, depending on the time of day and day of
    the week
  • Audit network activity for a particular user or user group
  • Monitor applications’ network activities and discovery of malicious programs
    (viruses, Trojans, etc.) in real-time
