Three questions every analyst asks before acting on this signal.
It indicates that the ASN belongs to a clearly identified regulated network category such as major cloud/CDN providers, government infrastructure, or academic and research networks.
Only network types with strong, verifiable ownership and governance signals are included to maintain high precision and avoid introducing ambiguous or weak safe bias into risk scoring.
This is a high-confidence safe-bias context signal. It does not override malicious evidence, but it helps analysts quickly recognize traffic originating from well-known and regulated network environments.
A realistic shape of the entry the engine appends to the risk_signals array when this signal fires. Evidence keys are subgroup-default; per-signal overrides documented in the API reference.
