Commtouch announced a new version of our GlobalView Mail Reputation Service, that incorporates enhanced reporting as well as enhanced logic capabilities.
From earlier posts you’ve seen that zombies (aka bots) are responsible for almost all of the unwanted mail traversing the Internet. With even a not-very-good reputation service, you should be able to cut those quantities by quite a bit. With a top-notch one (like, ahem, you-know-who’s) you should be able to eliminate the vast majority of those messages at the network perimeter – somewhere in the range 90 percent.
Why use a reputation service, when a regular email filtering solution (anti-spam, anti-virus) provides even higher detection levels than that? Well, think of all the IT resources wasted on transmitting unnecessary messages – bandwidth, storage, mail servers. Even if your mail filter identifies most of the spam/malware/phishing, it still has to touch each one of those messages – receive it, identify it, decide whether to quarantine it, delete it, deliver it, and potentially archive it until the end of time even if it was never opened.
Cut out a huge chunk of the messages entering your organization or traveling through your ISP, and you can cut down your storage needs, even reduce the number of mail servers you are using. We are talking about real, quantifiable cost savings.
Also, from the threat perspective, wouldn’t you rather deflect inbound threats at the perimeter, before they’ve even touched anything in your network?
Since this is Commtouch’s third major release of the GlobalView service, we’re now at the stage where we’re adding lots of usability features, such as improved reporting and tailorable throttling logic. The press release about the launch goes into a bit more detail on these new functions.
By the way, always one to try out a new communication method, I wrote up a Google Knol on the subject of reputation services. I encourage you to read it, comment on it, review it, even to revise it (although I will be moderating the revisions, just like we moderate comments on this blog – did you know spammers actually try to put spam links in the blog comments?!).
