Squidblacklist.org is the worlds leading publisher of blacklists tailored for squid proxy. The data that we use to generate the blacklists that we offer is compiled from various sources including some of the top security researchers and threat mitigation organizations. We incorporate all of the best publicly available data, as well as aggregate from our own research. Then, the data is combined, parsed for dupes & errors, formatted for squid, ultimately the lists are tested and reviewed in a production environment before being published.
Squid Prime Blacklist
The Squid Prime blacklist is one that contains all threats, it is compiled from various sources, from other publicly available lists across the web, and compiled from our own aggregate. I also monitor the traffic of few open access points, which gives us a nice edge when it comes to blocking porno and proxies. I have drawn from the best and most thorough available lists, expanded on them, formatted them for squid as well as your hosts file. You are free to download and use these blacklists in any way that you like, you may reproduce them and share them with your friends or do anything with them that you desire (subject to the terms of our creative commons license).
Squid Porn Blacklist
When combined with a squid proxy, we are confident that our porn blacklist is the strongest and most effective filter you will find for blocking porn, that is to say, over any other free porn blacklist on the web readily available at this time. We have found that none of our competitors even come close to matching what we have done with this list. It contains adult sites, dating sites, cp sites, pedophile sites, zoophilia and more. Did I forget to mention that its free?
United States Government, Law Enforcement, Military and Intelligence Agency, Defense Contractor Blacklist
Our United States government blacklist is directed towards users and administrators who wish to block unwanted communications with sensitive United States government networks. It does not include networks that are home to useful hosts or sites such as the social securtiy administration, the us postal service, or your local unemployment office website. This list is not intended be used to block government service type websites that we all use. But it is designed to block the sensitive US Government networks that you likely, really do not want traffic from your network reaching. It is a simple CIDR formatted list. You could use it for your firewall rules just as easily as you could for a squid acl. Note that this list is in no way meant to be used for malicious purposes. This list is intended to be used for legal network security only. No other public source has published a more thorough list of US Government ip ranges, undoubtedly there are many more undiscovered networks that are not yet known and thus, not included in our list, However, it is the most complete list of USG ranges publicly available, and we update it regularly. It is available for download at iblocklist.com (requires an iblocklist subscription).
