Charles Proxy for mobile traffic inspection

Network analysis, device automation and reproducible security tests.

Testing and device labs1 min readEditorial methods

Charles Proxy supports mobile connection diagnostics. Use separate test accounts, test certificates and controlled builds without weakening production verification.

Evaluation approach

Traffic recording, connection inspection and supported fault simulations help explain mobile flows. HTTPS inspection requires suitable test certificates and application trust settings. Check current product documentation for licensing and platform support.

Application example

Observe how your test application retries verification on a poor connection. Use back-end records to confirm that the transaction does not run twice.

Limits and considerations

Shipping a certificate trusted only for testing can create a vulnerability. A working proxy does not prove coverage of every network stack.

Separating network and application problems

Record the device's proxy and trust settings during a Charles session. A request appearing in the tool does not prove that the server processed it. Follow the response, transaction record and user screen together.

Restore network settings after testing so later performance and security checks are not affected by the earlier proxy configuration. Share project files containing account and session data only with the relevant investigation team.

Checks and decisions

  • Separate test trust
  • Clean recorded data
  • Track repeated requests

Charles is useful for developer-focused network diagnostics; it does not automatically produce a Mobile RASP resilience assessment.
