Checkmarx Fusion: How Hybrid Scanning Raises SAST Accuracy
Checkmarx Fusion is a hybrid vulnerability detection layer in Checkmarx One that combines deterministic, rules-based SAST with a language-agnostic AI engine and curated frontier AI models, reconciled into a single result set. Checkmarx reports an F1 score of 0.741, versus roughly 0.20 for legacy rule-based SAST, and describes the approach as producing consistent results across scans while extending coverage to vulnerabilities with no existing rule or CVE.
