There was a download of PortsLock® 2.0 on the developer's website when we last checked. We cannot confirm if there is a free download of this software available. The PortsLock® installer is commonly called PLManager.exe.
We recommend checking the downloaded files with any free antivirus. This software was originally designed by DeviceLock, Inc. The program lies within Internet & Network Tools, more precisely Network Tools. Also the tool is known as "PortsLock". The following versions: 2.0 and 1.5 are the most frequently downloaded ones by the program users.
From the developer:
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.
You may want to check out more software, such as Plesk for Windows, FRITZ! or JaSFtp7, which might be related to PortsLock®.
