Jeff released another report: He is looking back into one year of Windows Vista. We had the discussion about the value of vulnerability comparison and I do not want to open another discussion thread about that. But as long as we hear that our products are less secure than others because we have sooo much vulnerabilities, these reports are important for us internally (we know where we stand) and externally to communicate our findings – and they are pretty interesting.
Have a look at the report at Download: Windows Vista One Year Vulnerability Report
Last but not least it was interesting to see that readers of my blog are looking into these things as well: Vista logged fewer vulnerabilities in its first year than XP, Red Hat, Ubuntu, and Apple Mac OS X did in their first years
