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
