IPCop is an open source Linux-based network gateway and firewall software that provides protection against malicious traffic and threats on the internet. It is designed to be easy to install and configure, and provides a secure, reliable and cost-effective firewall solution for home and small office networks. IPCop is a Linux-based operating system, and works by allowing or blocking access to the internet for computers in the local network. It can be used to protect the network from threats such as viruses, worms, Trojans, spyware, and other malicious software. It also provides access control, allowing users to restrict access to certain websites, services, and applications. Additionally, IPCop includes features such as web content filtering, network monitoring, and logging. IPCop is highly configurable, allowing the user to customize their settings to their specific needs.
It has actually been actively developed and, moreover, in a country that is not under direct control of the NSA or GCHQ, respectively. As IPCop seems to be dead (no new version for about 2 years now), IPFire has taken the best of IPCop and improved it a lot.
