List detection rules
fires and last_fired_ns count matches on hosts within your key’s scope. When a rule fires, the match also appears as a finding in GET /v1/findings (with source: "detection_rule") and triggers the detection_rule.matched webhook event.
Scope behavior
Rules are returned when they apply to hosts your key can see — either all-hosts rules or rules scoped to at least one host in your scope. For rules that span additional hosts outside your scope,host_ids and workload_scopes list only the hosts you have access to.
Rule management (create, edit, delete) is available in the dashboard.
