CSP Policy Auditor | Free Online Tool

What is the Content-Security-Policy Auditer?

The CSP command and source are analyzed, and unsafe-inline, Wildcard, lack of fallback and common protection instructions are checked. ToolHub places the core operation in the browser, so that desktops and action devices can be used immediately, without registration of account numbers, or necessarily to the back.

How to use this tool?

Enter the data according to the field prompts and select the required processing method.
Click "Process Now" to view the results, indicator summary and necessary error messages.
After confirming that the content meets actual needs, you can copy the results or download them into files for further use.

Suitable use cases

All processing is done in the current page break, especially for workflows that do not want to post in-house information to a remote service.

Interpretation of results and precautions

The static audit does not verify that the page actually contains the resource and suggests that it be matched with the Report-Only observation. The tool validates the basic input format and provides readable error messages, but the formal environment should be reconfirmed according to source specifications, business rules or professional requirements.

Browser and device support

CSP Policy Auditor supports current Chrome, Edge, Firefox, and Safari releases. Mobile and desktop layouts use the same validation rules documented on this page.

What are the limitations of this tool?

What this page actually processes

Field	Control	Default example	Validation role
Content-Security-Policy	Multiline text	`default-src 'self'; script-src 'self' https://cdn.example.com; style-src 'self' 'unsafe-inline'; object-src 'none'; base-uri 'self'`	Content-Security-Policy is read by the browser as a multiline text value before the tool runs.

Reproduce the built-in example

Start with Content-Security-Policy = default-src 'self'; script-src 'self' https://cdn.example.com; style-src 'self' 'unsafe-inline'; object-src 'none'; base-uri 'self', then run CSP Policy Auditor. Change one input at a time so the effect on the result remains traceable.

After validating content-security-policy, the page displays its result in the output workspace and enables the relevant copy or download action.

When to use it and how to interpret the result

All processing is done in the current page break, especially for workflows that do not want to post in-house information to a remote service.
