Biggest opportunity: Swap “content security policy” for “csp header”. “content security policy” isn't earning its slot: you're not in the first 24 results for its own search. “csp header” sits at #4 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →5.4%
of downloads still active
At least 200 of 3.7K lifetime downloads are still running, above its category: the median Security plugin keeps 1.4%, across 1,060 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Security plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 1 release in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.
| Keyword | wp.org | On merit | wp.org move, 90 days |
|---|---|---|---|
| csp your tag | #1 | #5 | up 1 |
| sha256 hashes your tag | #1 | #2 | 0 |
| csp header | #4 | #12 | down 1 |
| hashes | #4 | #11 | up 2 |
| nonces your tag | #14 | #24 | up 1 |
| content security policy your tag | Not in the top 24 | ||
| security headers your tag | Not in the top 24 | ||
6 searches this plugin appeared in over the last 90 days, 5 listed. 1 left out as unrelated or noise (years, numbers, stray words). 2 of its tags aren't in the top 24 for their own search.
What to do about it
- Swap “content security policy” for “csp header”. “content security policy” isn't earning its slot: you're not in the first 24 results for its own search. “csp header” sits at #4 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- One page off on “nonces”. #14 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

I downloaded this plugin and modified it for my site. I would recommend doing that. The plugin hooks into the ‘template_redirect’ hook. At that point the source for the page has been generated by themes and plugins and is ready to be sent. The plugin looks through the generated source and makes nonces for all inline scripts and styles. It modifies the source so the inline scripts and styles have a nonce=’some-nonce’ statement in them. It creates a Content-Security-Policy which includes those nonces. However, each site has its own CSP needs, and so modifying the plugin to tailor the CSP to your site is not that difficult to do. That is what I have done.

doesn’t seem to work properly with w3tc. hope it will get updated at some point.

The plugin works as advertised however, it does not let you modify the CSP header resulting in a less than ideal CSP header. The header this plugin serves provides no protection against clickjacking and allows all external scripts. This topic was modified 3 years, 10 months ago by anonymized-20439159.

This is the most ‘straight to the point’ CSP tool that I’ve found. So far, so go.
