Sophos wins VB anti-spam comparative test

VBSpam verified awardThose awfully nice people at Virus Bulletin have just published their March 2011 edition, which includes a comparative test of 20 different anti-spam solutions.

Over 16 consecutive days, Virus Bulletin tested the different products against a total of 140,800 emails – 137,889 of which were spam. Legitimate messages were sent in a number of different languages to represent the international nature of email.

I’m delighted to say that Sophos’s email appliance performed superbly, achieving a 99.91% spam catch rate with no false alarms.

This meant Sophos appeared in the very top right corner of Virus Bulletin’s spam quadrant (that’s definitely the corner you want to be in), and outperformed a number of competitors.

As Virus Bulletin explains, their chart plots spam catch rate against false positive rate.

"..Sophos Email Appliance is a very good spam filter, as demonstrated in the current test. The third highest spam catch rate combined with no false positives at all gave it the highest final score and the product's developers in the UK and Canada should consider themselves the winners of this test."

More information about the VBSpam comparative testing can be found on Virus Bulletin’s website.

We try not to toot the horn for Sophos’s products too much on the Naked Security site (figuring you’re more interested in reading about emerging threats than being pestered by us trying to get you to buy our solutions), but hopefully you won’t mind if I raise a glass to the guys and gals in our labs, testing and development teams for the excellent result.

Well done chaps! This award follows hot on the heels of other good news for Sophos’s email security solution, which was named “Best Email Security” product at the SC Magazine Awards in San Francisco last month.
