Capital One open-sourced VulnHunter, an AI-powered code security tool that applies attacker-perspective analysis to source code, identifying exploitable defects and proposing targeted remediations. This enables developers to proactively fix vulnerabilities before AI-powered attacks become more prevalent and accessible. By minimizing false positives through a falsification engine, VulnHunter shifts the developer's burden from triaging false alarms to immediate, evidence-backed code repair. VulnHunter cuts false-positive rates to near zero by running a falsification engine that actively tries to disprove its own findings before surfacing them. This means developers can trust every alert and act on it immediately, slashing triage time and letting security scale with CI/CD pipelines instead of blocking them. If you’re shipping agentic code-review tools, this is the bar for accuracy and developer adoption—anything less will drown teams in noise.
