What Are the Best Software Supply Chain Security Tools in June 2026?

Software supply chain security tools have become essential as attackers increasingly target dependencies, build pipelines, and AI-generated code, which traditional security tools often overlook. These tools focus on external components like open source packages, third-party APIs, CI/CD pipelines, and build infrastructure, providing measures such as SBOM generation, dependency and vulnerability scanning, and pipeline integrity monitoring. They also offer identity-aware routing, which resolves security findings to specific developers, and can govern code at the generation stage, including AI-generated code. Among the tools discussed, Arnica is highlighted for its pipelineless architecture, continuous monitoring, and identity-based governance, which enable comprehensive coverage without the need for CI/CD integration, making it suitable for teams looking to secure their software supply chain without disrupting development workflows.
