Response to exploited bugs
Not rated. 2 reviewed zero-days on record. A grade needs at least 3.
Fixing privately reported bugs
Not rated. No private reports in the grading window.
What a grade means. B means the vendor met the public norm, such as a first fix within 7 days of the first public report or a private fix within 120 days. Taking half the norm time scores 92, an A. Taking twice the norm time scores 43, a D−. How grades work
Why these grades
Every clock starts at the first public report.
- Response to exploited bugs: not rated. 2 reviewed zero-days in the last 36 months. A grade needs at least 3.
- First fix within a day for 1 of 2 zero-days. The other one took 5 days.
- Every supported version fixed within a day for 1 of 2 zero-days. The other one took 5 days.
- First advisory within a day for all 2 zero-days. Its advisory said the bug was being exploited in 1 of 2.
- Fixing privately reported bugs: not rated. No private reports in the last 36 months.
- 1 of 3 reviewed exploited bugs had a public fix before exploitation was reported. It does not count toward the response grade.
- NR (not rated) means a subject has fewer than 3 data points from the last 36 months, or their recency weights add up to less than one current data point. For response, a data point is a reviewed exploited zero-day. For private fixes, it is a private report (one vendor, one report date). KEV listings alone never rate a vendor. A grade is provisional when the vendor's own evidence does not yet outweigh the starting value, or confidence is below medium.

One row per exploited incident, newest first. A tick at the start means a fix existed when the bug went public.
