      Witness prevents tampering of build materials and verifies the integrity
      of the build process from source to target. It works by wrapping commands
      executed in a continuous integration process. Its attestation system is
      pluggable and offers support out of the box for most major CI and
      infrastructure providers. Verification of Witness metadata and a secure
      PKI distribution system will mitigate against many software supply chain
      attack vectors and can be used as a framework for automated governance.
