Standing S0007
Reach is how much of ATT&CK this tool touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 825 ATT&CK software entries only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.
Reach
5th percentile · 95% of 825 ATT&CK software entries have more Enterprise techniques.
21st percentile · 79% of 825 ATT&CK software entries have more tactics spanned.
61% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.
85% of the population shares a single value across only 8 distinct values, so a percentile here would rank the tie, not the entity.
Coverage
1st percentile · 99% of 825 ATT&CK software entries have more detection rules per technique.
