- Firewall learners and people reviewing their own rules
- Worth noticing
- The page says findings are review prompts, not confirmed vulnerabilities, and imported exports are not uploaded.
Field notes
The workspace pairs sample-only policies with questions about traffic direction, ports, default policies, and connection state; answers unlock a policy map and technical explanation. The page lists nine interactive examples, then points to hardening guides and a glossary; it also says imported exports are parsed in-browser with WebAssembly and that findings are prompts rather than confirmed vulnerabilities.
