An enterprise level email security and backup services firm


Nxth0p - Is a Chicago based company providing hosted spam filtering and managed email backup services for small, medium and large businesses. At Nxth0p, we are passionate about earning customers for life. We believe technology and its implementation should be invisible yet provide clear and tangible benefits in support of a business's objectives.


First and foremost, we actually do block spam. Secondly, we provide excellent support. There are many things that set us apart, but the one that we've work the hardest for is our support ethic. We hear that with many other services, it's practically impossible to actually speak to another human. People are always surprised to call during office hours and speak to us. However, that's nothing compared to the first time one of us actually calls a client to see how things are going.

We've been at this for a while, in fact, our lead engineers began at Postini. Once we built geographically redundant clusters of high-end spam filters, we surrounded it with a proprietary anti-spam pre-filter system that has grown and improved over the years. Listening to suggestions from clients, added to our experience in the ongoing fight against spam, we've developed a very effective anti-spam system, with many clients that have been with us for years.
