Managed Spam Filter Service

Domain wide filtration for your business.

We manage and maintain the spam filter for you.  There is nothing to install on your server!  We also hold your email if your server is offline (backup mx / mailbagging).

DNS Web Filter System

Hosted, or installed locally, your choice.

We have a very easy to deploy web filter system.  By using DNS to filter websites we do not require anything be installed on each workstation. 

We even offer a way to host the DNS Filter for you for a completely managed system.

Technologies

Information about our web spiders, lists, storage systems, and more.

The technology you choose to deploy for your filtration and categorization needs must be robust and ready to deliver.  Emerald Technology is the developer of all the systems you will read about on this site.  If you need anything customized, we can do it.

Categorized Domain Lists

Over 3 million domains across 44 categories...

Categorized lists of URLs are worthless if they are not constantly updated.  We crawl over quarter million domains per day and update our lists every 15 minutes to ensure timely and accurate information.

Licensing

Leading companies use our filtration systems, and domain databases to power their products.

Technology that is designed to meet your needs, and a partner that will work with you.

We license our products and technologies to third parties for inclusion into their own products.
