(sometimes we provide two download links because it may happen that the main server / link is overloaded or slow or non responding - the files are identical. Just choose one, save to the Desktop, double click to install)
Disclaimer: to our best knowledge this download comes from a website that is
safe (the last time we checked it, it was), but for your peace of mind (and better safe than sorry) we advise you to run an
antivirus on the downloaded file. Do not rely on MSWindows, Internet explorer, or on the electronic signature: a unsigned download is usually as safe as a signed one, signed just means the author paid Microsoft or Verisign for a stamp, it does not mean verified. Please kindly
report us problems with detail (click here to report), if any.
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.

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.
Keep in mind that almost 80% of all security breaches come from the inside! PortsLock enhances access control possibilities for system administrators, helps them to build a more secure network environment, and protects corporate networks against attacks from the inside.
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.
