Standing S1043

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

Techniques1254th pct

54th percentile · 54% of 825 ATT&CK software entries have this many Enterprise techniques or fewer.

Tactics768th pct

68th percentile · 68% of 825 ATT&CK software entries have this many tactics spanned or fewer.

Threat groups061% tie · 22 values

61% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.

Campaign185% tie · 8 values

85% of the population shares a single value across only 8 distinct values, so a percentile here would rank the tie, not the entity.
