<p>Integrity-checker uses a mix of traditional and new techniques to scan your website for potential issues. First and foremost, it verifies that all installed code is identical to it’s original version. By comparing WordPress core, plugins and themes in your installation with the original versions available at wordpress.org, Integrity-checker can quickly determine if there are any changes you need to be aware of. Integrity-checker also lets you compare your local version to the original to help you determine if you’ve been hacked.</p>
<p>Additionally, Integrity-checker scans all installed files for permission issues. Ensuring correct permissions is vital for WordPress security, as with any PHP based web application.</p>
<p>Lastly, Integrity-checker will look through some of the basic WordPress configuration to look for common security problems like user enumeration, directory index weak credentials etc.</p>
<h4>Features</h4>
<ul>
<li>Helps you track down hacked WordPress files in core, plugins and themes  </li>
<li>Makes it easy to find issues with file permissions</li>
<li>Detects common configuration problems</li>
</ul>

Integrity Checker

I've modified the review after discussion with the author

This is a very useful tool! The free API limit might be a little low if you want to test the site recurrently but it's still a useful tool.

Promising!
