MISP Warninglists: Why Defenders Should Use Them Before Blocking IOCs

CyberKit field guide

MISP Warninglists help defenders identify indicators that need additional context before automated enforcement.

A safer pipeline

1. Ingest the indicator.
2. Normalize its value.
3. Check warninglists and local allowlists.
4. Enrich with context.
5. Only then consider blocking.

A warninglist hit is not a benign verdict; it is a signal to slow down automated enforcement.
