Checkmarx introduces Checkmarx Fusion for hybrid vulnerability scanning

Checkmarx said it introduced Checkmarx Fusion as a hybrid vulnerability scanning approach available in early access to Checkmarx customers. The company linked the release to a shift in how code is produced and the scale of vulnerability detection work across software development.

Checkmarx pointed to its 2026 Future of Application Security report, which it said found that 49% of production code is AI-generated. The company said this increased the volume and complexity of vulnerabilities beyond what existing tools and processes address.

Checkmarx Fusion combines Checkmarx AppSec engines with proprietary security context and a leading frontier model from Anthropic. It operates as an integral component of Checkmarx One, using outputs from multiple scanning engines to confirm true positives and reduce false positives.

Checkmarx said Fusion uses a deterministic foundation based on two decades of Checkmarx AppSec research and a multi-model AI engine for languages outside a fixed rule set, including AI-generated code. It said customers can select among Claude models for deeper reasoning and that scanning workloads run entirely within their own cloud environment using Amazon Bedrock, keeping source code within the infrastructure boundary. Checkmarx said it will be demonstrated at Black Hat USA in Las Vegas, at booth #4553.

“We are at an inflection point in application security,” said Sandeep Johri, CEO of Checkmarx. “AI has driven code volume, delivery speed, and risk complexity beyond what any organization can manage with yesterday's thinking. Checkmarx Fusion is the answer to that moment: deterministic precision and frontier AI reasoning, delivered in an integrated enterprise-grade cloud architecture. This is how code security has to work from here.” “Enterprise application security is one of the most consequential domains for AI reasoning, because the complexity is high, the cost of error is real, and speed matters,” said Ashraf Alhashim, Head of Enterprise Security GTM, Anthropic. “Checkmarx Fusion is a compelling example of what becomes possible when organizations bring frontier AI intelligence to bear within the kind of deep security context Checkmarx has spent decades building.”
