Joomla, WordPress, Drupal and other popular web apps are the most common target of web attacks these days, and not everybody is updating this apps as they should to keep their websites safe from vulnerabilities. Suhosin doesn’t update your app code (that’s your responsibility) but it will add another great layer of protection against common attacks for the PHP code your apps run.

How can I install Suhosin on cPanel in order to protect my websites?

On cPanel servers the installation is pretty easy, just run this command and it will do it all for you:

/scripts/phpextensionmgr install PHPSuHosin

Verify Suhosin installation by typig the following command:




php -v

If you see:
