Those 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.
