+# Security Policy
+
+## Supported Versions
+
+Only the latest published version of each `@redhat-cloud-services/*-client` package receives security updates. Upgrade to the latest version to ensure you have all fixes.
+
+## Reporting a Vulnerability
+
+If you discover a security vulnerability in this project, please report it responsibly:
+
+1. **Do NOT open a public GitHub issue** for security vulnerabilities.
+2. Report via [Red Hat Product Security](https://access.redhat.com/security/team/contact/) or email `secalert@redhat.com`.
+3. Include a description of the vulnerability, steps to reproduce, and any relevant logs or screenshots.
+
+You should receive a response within 5 business days. We will work with you to understand and address the issue before any public disclosure.
+
+## Security Practices
+
+This project follows these security practices:
+
+- **Pinned dependencies**: GitHub Actions use commit SHA pinning to prevent supply chain attacks.
+- **CODEOWNERS protection**: CI/CD configuration, git hooks, package manifests, and npm configuration require admin review.
+- **Signed releases**: Release commits and tags are GPG-signed.
+- **npm provenance**: Published packages include [provenance attestations](https://docs.npmjs.com/generating-provenance-statements) for supply chain transparency.
+- **Automated dependency updates**: Renovate monitors for outdated and vulnerable dependencies.
+- **Pre-commit hooks**: Husky enforces test execution and commit message validation before every commit.
+- **Least-privilege CI**: PR workflows run with read-only permissions; write access is scoped to the release job only.
+- **Conventional commits**: Commitlint enforces structured commit messages to maintain a clear audit trail.
