Cut the Noise: Smarter Deduplication with Agentic AI

The report describes HackerOne's Deduplication Agent, an agentic AI system that cross-checks incoming vulnerability reports against global patterns (CWE, CAPEC, payloads, metadata) to identify duplicates before analyst review. It emphasizes reduced median deduplication time (from 94s to 62s), 80%+ coverage across vulnerability types, 80–95% recommendation accuracy with human-in-the-loop oversight, and benefits such as improved efficiency, consistency, and fairness in vulnerability validation.
