Which channel to use

• A bug or a wrong finding: open a GitHub issue. Include the command, the Penthera version and the rule ID.
• A question or an idea: start a GitHub discussion.
• A vulnerability in Penthera itself: report it through a private security advisory, and not in a public issue. The security policy says what to expect.
• Research or press: email daan@penthera.org.
• News from the project: @penthera_org on X.

If you own a site

To keep the live check off your site, add a User-agent: Penthera-QuickCheck group with Disallow: / to your robots.txt. The terms show how, and list every request the check makes.

What it is not

This is not a support desk with a response time. Penthera is free software, maintained part time. It is also not a way to ask us to test a site: run npx penthera yourself on what you own or may test.

What happens to what you send

This page has no form, so penthera.org stores nothing you send. Google Workspace stores email. Issues and discussions are public on GitHub, so leave out secrets and private data. Trust lists the services that run penthera.org.
