What is Threat Intelligence Sharing?
Threat intelligence sharing is when fraudsters, device fingerprints, mule accounts, BIN corridors, IP/ASN hotspots get passed around trusted partners. Speed is the goal: reduce an attack’s half‑life from weeks to hours. Formats and pipes (APIs, feeds) are less important than trust, legal footing, and relevance.
Program tips: curate signals with context and expiry; don’t dump raw PII where it isn’t needed; measure lift—lower losses, faster triage, fewer false positives. Join sector groups where rules are clear and reciprocity is real. When shared intel touches identity, route risky flows through identity verification rather than blanket blocks.
