SigRun

Sign your artifacts source code or container images using Sigstore chain of tools & Known Container Image Build tools, Save the Signatures you want to use within your Infra, and Validate & Control the deployments to allow only the known Signatures. Shift-left your supply chain security!

What's with the Name (in case if you are curious)? You can think of multiple ways. It has a flexible interpretation, like Signatures for Runtime or Runtime Signatures or Sign Software for Runtime use. Whatever you want to imagine! :smiley: #
