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. The essence is that users do not 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. What's also important is that PortsLock works perfectly fine alongside other personal firewalls and routers installed on the same computer.


While no software solutions can completely eliminate risks, the combination of DeviceLock and PortsLock significantly reduces the vulnerability of your network to attacks both from outside and from within. These applications were extensively tested in corporate environments and are being relied on by many companies around the world. They win respect and recognition from system administrators and IT security professionals who employ them.
