  "summary": "Google has unveiled its AI-powered security agent, PageBreak, which has discovered more than 500 cross-site scripting (XSS) vulnerabilities across its web applications since its full operation began in January. The agent uses Gemini models to autonomously investigate potential vulnerabilities but only reports them after deterministic validators successfully reproduce the exploit against a running application, resulting in a near-zero false-positive rate. PageBreak's development prioritizes deterministic validation, ensuring that every vulnerability hypothesis is tested against a live environment with a real exploit before being reported. This approach minimizes false positives and allows product teams to focus on high-confidence vulnerabilities.",
