Tool guide limitationsGuides explain the intended workflow but cannot cover every device, provider or operating condition.

Interfaces and external services can change. Follow the current on-screen controls, check dates and vendor documentation, and verify important results independently before acting on them.

Important: Do not rely on this result alone for purchasing, configuration, security, safety, compliance, contractual or fault-diagnosis decisions. Results can be incomplete, delayed, misleading or wrong. Verify important findings with the relevant provider, manufacturer documentation and an appropriate independent test or qualified professional.

Firewall Configuration Health guide

Review a firewall configuration locally without starting a migration.

Open Firewall Configuration Health

What you need

  • A text configuration or pasted sanitised configuration

How to use it

  1. 1Select a local file, paste text or load the safe example.
  2. 2Review high, medium and manual-review findings.
  3. 3Confirm duplicate, shadowing, unused-object, service, NAT and reference candidates in the native platform.
  4. 4Download the JSON report for peer review.

Understanding the results

  • A candidate is a prompt for investigation, not proof of a fault.
  • No heuristic finding is not proof of a healthy configuration.

Recommended next actions

  • Verify every material finding in the destination vendor tools and prepare a rollback plan.

Common problems

  • Included contexts, built-in objects and vendor aliases can look missing or unused.
  • Rule semantics and shadowing differ by vendor and software release.

Privacy and security

  • The configuration stays in the browser, but users must still remove or rotate exposed secrets.

Worked example

Scenario
Pre-change firewall review
Example input
A sanitised policy export with a duplicate rule and Telnet service
How to read it
The tool highlights both as review findings without requiring a migration destination.

Limitations

  • This does not replace vendor syntax validation, policy simulation or qualified security review.

Do not rely on one result for a production, security, safety, purchasing or contractual decision. Verify important findings independently.
