AGMP Partners The Current State of Zero-Day Vulnerability Trends in Late 2025 As we close out the first half of 2026, the landscape of zero-day vulnerabilities has continued its relentless evolution, pushing security teams to their absolute limits. We’re well past the days when a zero-day was a rare, high-value asset, primarily the domain of state-sponsored actors. The democratization of exploit development, coupled with a booming exploit market, has irrevocably altered the defensive posture required for any organization of significant size or intellectual property. What we've observed over the past 18 months isn't just an increase in volume, but a noticeable shift in targeting and access vectors. Critical infrastructure (CI) and supply chain exploitation remain paramount, but there's a growing sophistication in lateral movement and persistence techniques within cloud environments, often
