Standing S0651
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
54th percentile · 54% of 825 ATT&CK software entries have this many Enterprise techniques or fewer.
80th percentile · 80% of 825 ATT&CK software entries have this many tactics spanned or fewer.
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
50th percentile · 50% of 825 ATT&CK software entries have more detection rules per technique.
Detection coverage S0651
435 distinct rules cover the 12 techniques recorded for this tool. The 455 technique-to-rule mappings resolve to 435 distinct rules, because one rule can cover several techniques. 330 Sigma · 105 Splunk.
