We are beyond thrilled to announce a significant milestone for StepSecurity Harden Runner, one of the flagship products of our startup. As of this week, Harden Runner has been successfully adopted by over 1000 public GitHub repositories! This is not just a testament to the value that our security solution brings to the developer community but also a celebration of the collaboration and support we've received since the inception of our product.  

A brief history of Harden Runner

Harden Runner was introduced in February 2022 to prevent SolarWinds and Codecov-style CI/CD supply chain attacks. By installing a security agent on the GitHub-hosted runner, it provides three essential security features:

1. Preventing exfiltration of credentials

2. Detecting tampering of source code during build

3. Detecting compromised dependencies and build tools

After months of rigorous testing, feedback, and improvements, Harden Runner reached General Availability (GA) in November 2022 for GitHub-hosted runners.

The Growth Journey

The adoption of Harden Runner has seen steady growth since its GA release. It took 10 months for the first 500 repositories to embrace our security solution, but the momentum only accelerated from there. In just five short months, another 500 repositories adopted Harden Runner, bringing our total to a staggering 1000 public GitHub repositories!

This remarkable growth showcases the increasing awareness and importance of security in the software development process. We are grateful for the trust that the developer community has placed in our product, and we're committed to continually enhancing Harden Runner to meet the ever-evolving security challenges in software development.

Harden Runner: Securing Both Open-Source Communities & Enterprises

We understand the diverse needs of our community and the importance of providing a solution that caters to a wide range of use cases. That's why Harden Runner is designed to work seamlessly with both public and private repositories.

For public open-source repositories, Harden Runner can be easily integrated into your CI/CD workflow without the need to install any App. It provides an additional layer of security, helping you ensure that your open-source projects are safe from tampering and credential exfiltration.

When it comes to private enterprise repositories, Harden Runner GitHub Action, along with the Harden Runner App helps ensure that your proprietary code and credentials are protected during the build process, providing peace of mind and reducing the risk of security breaches. For our paid plans for enterprises, please refer to our website.  

Exciting Future Developments: Harden Runner for Self-Hosted ARC Runners

While we celebrate this milestone, we are equally excited about the road ahead. We are currently developing Harden Runner for self-hosted ARC runners. This move will extend the benefits of our security solution to even more CI/ CD environments. We understand that many organizations and projects have unique requirements that necessitate using self-hosted runners, and we are committed to ensuring that these environments can also benefit from the enhanced security provided by Harden Runner.
