+# New Security Check for GitHub Actions in Public Repositories
+
+To improve the security posture of GitHub Actions, mitigate PWN request vulnerabilities, and other high-severity CI/CD issues, we are introducing an automated security scan for GitHub Actions for all Alphabet-owned public repositories. This scan will run as a new check on Pull Requests.
+
+## What's changing?
+
+The workflow triggers on Pull Requests affecting `.github/workflows` or `actions` directories to parse for vulnerabilities.
+
+## Impact on Your Pull Requests
+
+You will notice a new status check appearing on your Pull Requests in Alphabet-owned public repositories. This check will **NOT** block merging your Pull Request, even if it doesn't run or fails.
+
+## Understanding Statuses:
+
+*   **Not Run:** For PRs created before implementation of the rule, the check might appear as not run. You can still merge.
+
+*   **Failing:** A failed status indicates potential security issues were found. You can still merge, though caution should be taken to ensure that the potential security issues found are mitigated.
+
+## No Required Action
+
+You do not need to take any special action to merge your PRs.
