Checkmarx has launched Checkmarx Fusion, a hybrid scanning product now available in early access to Checkmarx customers, combining Checkmarx application security engines and security context with Anthropic's Claude model. The product addresses rising software security risks tied to AI-generated code and increasingly complex development environments. In its 2026 Future of Application Security report, Checkmarx said 49% of production code is now AI-generated. Fusion is part of the Checkmarx One platform, combining outputs from multiple scanning engines to confirm true positives and reduce false positives. Checkmarx cited benchmark performance, saying Fusion achieved an F1 score of 0.741, which it described as nearly four times the category average. The architecture uses a deterministic base alongside a multi-model AI engine. Customers can choose from Claude models for more demanding analysis tasks. Scanning workloads run within customers' own cloud environments through Amazon Bedrock, so source code does not leave their infrastructure boundary. "We are at an inflection point in application security," said Sandeep Johri, Chief Executive Officer, Checkmarx. "Checkmarx Fusion is the answer to that moment: deterministic precision and frontier AI reasoning, delivered in an integrated enterprise-grade cloud architecture."
