Third-party components
In addition to the Squid build itself, Squid Proxy Professional may bundle a small number of supporting third-party libraries and utilities. Each such component remains under its original license. A complete list of third-party components and their respective licenses is provided with the installer and on this page.

Independence and proprietary components
The Squid Proxy Professional management console, the Windows installer, the licensing system, and other components developed specifically for Squid Proxy Professional are separately licensed commercial software and are not distributed under the GNU General Public License. The terms of the commercial license apply to those proprietary components and are provided at purchase.
The boundary between GPL-licensed components and proprietary components is made explicit in the installed product. Proprietary binaries do not statically link or otherwise combine with GPL components in a way that would extend the GPL to those proprietary components.
