Governance principles

Defined boundaries.
Visible responsibility.

These principles guide how Griego scopes research, handles sensitive information, and coordinates security concerns.

01

Authorization before testing

Research must stay within an explicitly permitted scope. Ownership, test boundaries, and applicable program rules are established before work begins.

02

Minimum necessary access

Access should be limited to what the research requires. Sensitive data should not be collected or retained beyond what is necessary to document an issue responsibly.

03

Evidence with context

Security conclusions should be supported by reproducible observations, with scope, impact, and uncertainty made clear.

04

Coordinated handling

Potential vulnerabilities should reach the responsible owner through a private reporting channel. Publication decisions should consider remediation and the risk to affected users.

Documented website checks

Evidence you can inspect.
