  • Excellent

    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.

  • Seems to work well!

    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.
