Very interesting data, but how does it demonstrate that MS is, as of now, any slower at addressing vulnerabilities than any other vendor? The report is more than two years old (it says the data is from Feb 2009), and it is based on vulnerabilities discovered over the life of each product. That puts MS at an obvious disadvantage because it includes their "slow start" in fixing a host of early vulnerabilities, while excluding their more recent efforts, which are surely more respectable. Do you know of any data covering 2009 to now? That would be more useful.
