In our continuous pursuit to enhance CI/CD security, we’re excited to announce that Harden-Runner is now also supported on self-hosted VM runners. A development driven by enterprise demand, we’re thrilled to empower businesses running their build on VM runners and enable them to secure their CI/CD environments. If you’re using GitHub Actions on self-hosted VM runners and are looking for security options, contact us now to know how we can help you!  

Effortless Integration, No GitHub Action Workflow Changes Needed

Harden-Runner on self-hosted VM works without any workflow changes

The newly introduced harden-runner supports both persistent and ephemeral runners. Moreover, integrating this with your self-hosted VM runner is a breeze. Much like in self-hosted Kubernetes runner, you won’t need to make any changes in your workflow files for network and file monitoring. All you need to do is add the Harden-Runner agent to the runner image (like AMI) and it will automatically start monitoring all GitHub Actions workflows that use the image.

Battle Tested CI/CD Security  

Harden-Runner has been battle-tested by over 1600 open-source projects, 2,000,000+ CI/CD pipeline runs and 3900+ CI/CD workflows on GitHub-hosted runners where GitHub actions managed VMs are used. The same rock-solid technology is leveraged for self-hosted VM runners on cloud providers like Azure Virtual Machines, AWS EC2, Google Compute Engine, etc, to ensure security of your GitHub Actions workflows.  

CI/CD Native Network Firewall for Filtering Traffic

Other than monitoring traffic, Harden-Runner also lets you precisely filter the network traffic. With Harden-Runner GitHub Action, you can define authorized destinations for network traffic and filter or stop unwanted traffic for good. Further, based on monitoring, it will also recommend granular policies based on the past workflow runs that can be used to set allowed lists during network filtering. Whether you’re running ephemeral or persistent runners, you can rely on Harden-Runner to secure all your GitHub actions workflows.
