 - **Anomaly Detection:** Once the baseline is created, any future outbound calls not in the baseline trigger a detection.
 - **Block Network Egress Traffic with Domain Allowlist:** Optionally use the automatically created baseline to control outbound network traffic by specifying allowed domains, preventing unauthorized data exfiltration.

 For GitHub-hosted runners, Harden-Runner GitHub Action downloads and installs the StepSecurity Agent.

 - The code to monitor file, process, and network activity is in the Agent.
- The community tier agent is open-source and can be found [here](https://github.com/step-security/agent). The enterprise tier agent is closed-source. Both agents are written in Go.
- The agent's build is reproducible. You can view the steps to reproduce the build [here](http://app.stepsecurity.io/github/step-security/agent/releases/latest)
+- The community tier agent for Linux is open-source and can be found [here](https://github.com/step-security/agent). The enterprise agent for Linux and agents for Windows and macOS are closed-source.

 ## Limitations

 ### GitHub-Hosted Runners
-
-* 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).
 * 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) with built-in labels such as `ubuntu-latest`, as it needs sudo access on the Ubuntu VM to run. The limitation is if the entire job is run in a container. However, such jobs can be monitored when using custom VM images with GitHub-hosted runners. This is also not a limitation for Self-Hosted runners.

 ### Self-Hosted Actions Runner Controller (ARC) Runners

 * Since ARC Harden Runner uses eBPF, only Linux jobs are supported. Windows and MacOS jobs are not supported.

-### Self-Hosted VM (e.g. on EC2) and Bare-metal Runners

Author	SHA1	Message	Date
Varun Sharma	b09bb98e06	Merge pull request #680 from step-security/aws-code-build feat: AWS CodeBuild-hosted runner support, eBPF agent v1.8.14, Global Block List docs	2026-08-04 22:48:29 -07:00
Varun Sharma	35cd77bcf6	docs: document the Global Block List in the features list The Global Block List shipped earlier but was never added to the README. It applies to both the Community and Enterprise tiers, so it is listed under Community (Free), which the Enterprise list already inherits.	2026-08-03 19:24:47 -07:00
Varun Sharma	bb6dbef4bf	chore: rebuild dist with clean dependency install The bundle was previously built against a stale node_modules (@actions/cache 4.0.3) instead of the lockfile version (4.1.0), so the committed dist did not match a clean-install build and build-check failed.	2026-08-03 09:29:25 -07:00
Varun Sharma	98f73c5a0d	chore: update eBPF agent to v1.8.14 Bump the TLS and bravo agent downloads to agent-ebpf v1.8.14 and update the corresponding SHA256 checksums. Non-TLS, macOS, and Windows agents are unchanged.	2026-08-03 09:24:47 -07:00
Varun Sharma	54193c17a4	Reapply "feat(runners): detect AWS CodeBuild-hosted runners as third-party provider" This reverts commit `a3c333d110`.	2026-07-29 08:01:48 -07:00
Varun Sharma	d22dd481ce	Revert "fix(self-hosted): flush agent events at job end when deploy-on-self-hosted-vm is used" This reverts commit `0ff09412fb`.	2026-07-29 08:01:38 -07:00
Varun Sharma	0ff09412fb	fix(self-hosted): flush agent events at job end when deploy-on-self-hosted-vm is used The post step exited early for all self-hosted runners, so an agent deployed by the pre-step via deploy-on-self-hosted-vm never received the job-end signal (post_event.json) and never flushed process and file events. On ephemeral VMs such as AWS CodeBuild-hosted runners the VM is destroyed right after the job, losing those events. Record in GITHUB_STATE when the pre-step installs the agent on the VM and run the same Linux cleanup as GitHub-hosted in that case. Persistent self-hosted runners with a pre-installed agent keep the early exit.	2026-07-29 01:52:01 -07:00
Varun Sharma	a3c333d110	Revert "feat(runners): detect AWS CodeBuild-hosted runners as third-party provider" This reverts commit `bf94c00d6b`.	2026-07-29 01:49:47 -07:00
Varun Sharma	bf94c00d6b	feat(runners): detect AWS CodeBuild-hosted runners as third-party provider CodeBuild-hosted runner VMs are ephemeral, so the persistent self-hosted agent mode does not fit: its machine-scoped config carries no run_id or one_time_key (process and file events are not attributed to the run) and the post step exits without flushing events before the VM is destroyed. Detect CODEBUILD_RUNNER_TYPE=GITHUB and route to the per-run bravo agent, which reports run-scoped insights and flushes on job end.	2026-07-29 01:39:41 -07:00
Varun Sharma	514522c5e4	fix(self-hosted): resolve runner user when USER env var is unset On AWS CodeBuild-hosted runners the Actions runner executes as root and the USER environment variable is not set, so the self-hosted install path ran 'sudo chown -R undefined /home/agent' and agent installation failed silently. Resolve the user via os.userInfo() when USER is unset, and skip the chown instead of failing when no user can be determined.	2026-07-29 01:31:37 -07:00
