VBSpam comparative testing
VBSpam comparative testing is a regular independent comparison of anti-spam solutions.
The aim of these tests is to offer readers the best impartial advice about anti-spam security and the products on offer.
By using a combination of two live spam streams representing mailboxes all over the world, as well as a live stream of legitimate international emails, the VBSpam test aims to reflect the experience of a real end-user as accurately as possible.

While a single test can only show a snapshot of a product's capabilities at a specific moment in time, this long-term view can be used as a guide to how vendors are likely to perform in future. Listings of results by product are here.

The VBSpam chart allows at-a-glance comparison of product performances, plotting spam catch (SC) rate against false positive (FP) rate. The better performing products will appear in the top right-hand corner of the chart, with the highest SC rate and lowest FP rate.
