squidwall

If you're in search of a small, fast, and secure squid redirector, then look no further than squidwall. This software was designed with security as its top priority, so you can feel confident that your data is safe.

One of the standout features of squidwall is its pass-through antivirus scanning with clamav. This means that any files passing through are automatically scanned for viruses, providing an extra layer of protection.

In addition to this, squidwall offers user-based access control to squid (the internet), as well as host/IP based access control. This allows you to restrict access to certain users or groups, ensuring that everyone has the appropriate level of permissions.

Another great feature of squidwall is that neither it nor squid require a restart or kill -HUP if something is changed within the ACLs. The ACLs themselves are stored in two directories, with files that follow a specific naming convention: '+filename' for access granted, '-filename' for access denied, and '?filename' for access granted with scanning.

To use squidwall, you'll need PHP, the software itself, and Apache. However, with its impressive security features and ease of use, it's definitely worth checking out.
