+
+## Reporting a Vulnerability
+
+We take security reports seriously. If you discover a vulnerability in this project, please follow the steps below so we can address it responsibly.
+
+### How to Report
+
+Send your report to:
+
+**Email:** security@hexstrike-ai.example.com  
+**PGP key:** (optional) `0xYOURPGPFINGERPRINT`  
+
+Include:
+
+- A clear description of the issue.
+- Steps to reproduce (exact code/commands).
+- Impact and risk assessment.
+- Any suggested mitigation or fix.
+
+Your report will be acknowledged within **72 hours** and we aim to provide a resolution timeline shortly thereafter.
+
+### What Not to Do
+
+- Do not publicly disclose the vulnerability before it’s fixed.
+- Do not exploit the vulnerability on systems you do not own or have permission to test.
+
+---
+
+## Supported Versions
+
+We provide security fixes for the following branches:
+
+| Version | Supported        |
+|---------|------------------|
+| `main`  | Yes              |
+| `vX.Y`  | Yes (security only) |
+| Older   | No               |
+
+If your version is not listed, please upgrade.
+
+---
+
+## Security Response Process
+
+Once a report is received:
+
+1. We verify the issue and assign a severity level.
+2. We may request more information from the reporter.
+3. A fix is developed and merged into the supported branches.
+4. A public advisory or GitHub Security Advisory is published.
+5. Users are notified via repository release notes.
+
+---
+
+## Disclosure Policy
+
+After a fix is released:
+
+- We plan to publicly disclose the issue via the repository **Security Advisory** or release notes.
+- If the reporting researcher wishes to remain anonymous, that will be respected.
+
+---
+
+## Security Tools & Practices
+
+This project recommends but does *not enforce*:
+
+- Enabling Dependabot alerts for dependency vulnerabilities.
+- Using secret scanning and push protection in GitHub.
+- Running code scanning (e.g., CodeQL) as part of CI.:contentReference[oaicite:1]{index=1}
