VBSpam comparative testing

Latest Comparative Test

March 2014: In this month's VBSpam test, spam catch rates were high, but false positives were still an issue for some products - two of which failed to achieve a VBSpam award. The introduction of a slightly modified formula for calculating products' final scores has made achieving a VBSpam+ award a little harder - yet four products managed to do so. Check out how the products fared here.


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

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.

To display the VBSpam verified logo, an anti-spam solution must be capable of:

  • blocking a large percentage of emails in a live spam stream
  • correctly identifying all but a very small percentage of emails in a live stream of legitimate emails.

The detailed test methodology can be found here.

Results history

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 are here.

VBSpam results chart

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.

Any vendors interested in submitting anti-spam products for review are advised to contact Allison Sketchley, VB Sales Executive (+44 1235 544034; allison.sketchley@virusbtn.com) and/or Martijn Grooten, Anti-spam Test Director (martijn.grooten@virusbtn.com).

Yes - it keeps their users secure
No - it encourages users to continue to use a less secure OS
