A little bit about us.

There is a clear demand for a better blacklist. And with only a handful of questionable options available, we intend to fill that gap.

Initially, we began the service offering a handful of lists tailored specifically for use as Squid proxy access control lists, something that, at the time, was unavailable anywhere else. And we made them available for free, but as demand for our service began to scale, so did the workload required to continue our pursuit of a better blacklist, and so we became a paid service. It would be unfair not to acknowledge the continued consultation, code contributions, and advanced programming support provided by Douglas Berdeaux of Contributions, many of which serve as critical components to some of the most important functions of our automated domain addition and removal systems.

The blacklists that we now produce can be downloaded in several formats, ensuring broad compatibility with multiple web filter platforms and applications. 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 worldwide. The aggregate of this blacklist database is combined, parsed for dupes and errors, erroneous entries are corrected and the unnecessary sub domains are strategically removed for maximum effect. Ultimately, the data is inspected by hand before the final validation procedure and publication occurs. We strive daily for a higher degree of quality in our works. And as a result of a passion for quality, our domain blacklists are unlike anything found elsewhere.

The lists are updated every day, sometimes several times per day and hand validated before publication, this is usually done by Benjamin Nichols.
