Alot of anti-spam products are on the market now, and the list is growing quickly. While the market is starting to see some large antivirus and security companies buying small anti-spam entrepreneurs, there is still room for innovation, and small players can still play a part by keeping the larger companies from getting complacent. Note that many of the products listed here have won awards from various organizations. While the kind of award won and from whom can provide some insight into the product, I never take them very seriously, and rely on independent reviews for comparison.

Thorough review articles on anti-spam (and, any other) products can provide additional insight, but in my opinion, you’d be making a mistake if you consider awards in your selection criteria at all. I’m leaving out client-based products from this list because they are typically not aimed at business use. Spam solutions that run at the client level are fine products, but in a business environment, because you need central control of the product behavior that doesn’t include touching every workstation in the company. While the central control problem is solvable, I also dislike installing nonmanaged software on every workstation in the enterprise when I don’t have to. Please note that almost all the vendors with anti-spam products listed here also sell antivirus products as well. I only include an antivirus product if it’s a part of the anti-spam product. In the cases where I don’t list an antivirus product, it is almost certainly possible to purchase antivirus from that vendor as welland integrate it into the spam filter.

10.Proofpoint Messaging Security Gateway

www.proofpoint.com/products/msg.php

Proofpoint offers modular mail protection services either as a software package running on a provided hardened Linux OS with the Messaging Security Gateway, or as an appliance in the Protection Server. The Proofpoint solution really wants to be on the edge of your network (outside of the firewall, where other mail servers connect directly to it), in order to perform some of its connection-based testing. For example, Proofpoint does DNS and MX-level checking on the connection and on the From: address, as well as a dynamic check with its own database of known bad senders (basically, a private real-time blackhole list). The other interesting thing about this solution is Proofpoint’s “corporate lexicon” adapter that allows you to adapt the solution’s checking to your particular industry. That’s handy if you happen to be in certain industries that have some relationship to products typically sold by spammers, such as home loans or prescription medications.
