Kosai provides automated vulnerability remediation for open source software components across enterprise technology stacks. The platform uses a multi-model generative AI engine to scan, generate, and validate patches for CVEs in open source runtimes, frameworks, and libraries. The service addresses vulnerabilities in actively maintained projects, end-of-life software, and abandonware. Patches are generated to fix direct and transitive dependencies, with each patch tested for reliability and CVE closure before delivery. Organizations request coverage for specific open source components they need secured. The platform then continuously monitors these components, automatically generating patches when vulnerabilities are discovered. Patches are delivered as drop-in replacements in formats compatible with existing development pipelines. The solution supports multiple programming languages and frameworks including Java, Apache, PHP, Node.js, MySQL, .NET, Go, Ruby, Python, and PostgreSQL. Organizations can validate patches within their own testing environments before deployment. Kosai aims to reduce the time required to remediate open source vulnerabilities from weeks or months to minutes, without requiring code rewrites, platform migrations, or major version upgrades. The platform provides documentation and validation artifacts to support compliance and audit requirements.
