## Limitations

+1. Harden-Runner GitHub Action only works for GitHub-hosted runners. Self-hosted runners are not supported. We have started work on supporting [Kubernetes-Based Self-Hosted Actions Runners](https://github.com/step-security/harden-runner/issues/104).
2. Only Ubuntu VM is supported. Windows and MacOS GitHub-hosted runners are not supported. There is a discussion about that [here](https://github.com/step-security/harden-runner/discussions/121).
3. Harden-Runner is not supported when [job is run in a container](https://docs.github.com/en/actions/using-jobs/running-jobs-in-a-container) as it needs sudo access on the Ubuntu VM to run. It can be used to monitor jobs that use containers to run steps. The limitation is if the entire job is run in a container. That is not common for GitHub Actions workflows, as most of them run directly on `ubuntu-latest`.
