Update activity

How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Estimated value

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

Est. annual revenue

N/A

Est. acquisition value

N/A

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

    We were being harassed by our ISOs because the Acunetix scans kept coming back with HIGHs. Always XSS. We tried everything the report recommended as a remediation…nothing worked. This plugin should come bundled with WP. Or at the very least be added to the list of recommendations Acunetix suggests. Thank you for creating and sharing it.

    We were directed by a security researcher to an XSS vulnerability on our site, and this plugin seems to have solved the issue. Only plugin with this functionality I was able to find. Fairly straightforward and flexible.

    After running a full site scan using Acunetix and receiving hundreds of XSS alerts, this great little plugin secured the site. Bear in mind we have the free versions of Wordfence and iThemes Security installed, we incorrectly assumed that was enough… I’m not sure why this plugin isn’t used, or reviewed more. Thank you!
