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.
VBSpam certification is awarded to products that exceed a predefined threshold based on a combination of criteria relating to the products' spam catch rate and false positive rate.

Spam is changing continually, both in quality and quantity, and to protect inboxes and networks an anti-spam solution must be able to keep up with these changes.
An archive of VBSpam test results is available, allowing users to view the performance of a vendor or solution over time. 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 can be found in the VBSpam Test Archive.
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.
