Guidelines for good-faith security research on HLD Group systems.
Last updated: 21 May 2026
Version 1.2 · Review cycle: 365 days · View all frameworks
1. Our commitment
HLD Group welcomes good-faith security research that helps protect our customers and systems. We commit to working with researchers, not pursuing legal action for activities that follow this policy.
2. Scope
In scope:
- *.hldgroup.org properties and publicly documented APIs
- Customer trial environments explicitly labelled for testing
- Open-source repositories officially maintained by HLD
Out of scope
- Social engineering of personnel or customers
- Physical intrusion or denial-of-service
- Third-party services not operated by HLD
- Automated scanning that degrades production performance
3. Reporting
Send reports to [email protected] with description, steps to reproduce, impact assessment, and proof-of-concept if available. Encrypt with our PGP key where published.
4. Safe harbour
Give us reasonable time (typically 90 days) to remediate before public disclosure. Do not access, modify, or delete customer data. Stop testing when asked.
5. Recognition
We acknowledge valid reports in our hall of fame where researchers consent. Bounties may be offered at our discretion for critical findings.
6. Legal
Activities must comply with applicable law. Researchers must not violate privacy or damage systems.
