Best for Teams wanting a no-cost, community-sourced IOC feed to enrich existing security tools. SOC teams that want to suppress routine internet scanning noise and catch early exploitation of specific CVEs. Analysts wanting a fast, multi-engine second opinion on a suspicious file or URL, with the caveat that public submissions are shared with the community. Security teams that need attack-surface discovery plus adversary-infrastructure tracking from the same scan data.
