The initial release covers 60 critical Java vulnerabilities including Log4Shell and Spring4Shell, with Go, Node.js, .NET, and Python support planned for late 2026. Deployment is automated via a single command and integrates with Kubernetes and OpenShift without code or Dockerfile changes. The motivation is AI-accelerated exploitation: models from Anthropic, OpenAI, and Microsoft have demonstrated working exploits of known vulnerabilities in under a day, threatening to dramatically increase the historically low 5% exploitation rate of known CVEs. Runtime protection is positioned as a way to close the gap between vulnerability discovery and patch deployment. ## Full article daily.dev links to this article rather than hosting it.
