Several highly popular versions of PHP, used in nearly 85% of all PHP sites, are unsupported by the community. HardenedPHP secures old and unsupported versions of PHP - 4.4.9, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 7.0, 7.1, 7.2.

HardenedPHP secures old and unsupported versions of PHP. In those old versions, including the widely used 7.2, 7.1, 7.0, and 5.6, vulnerabilities, even if discovered, are not patched by the community. HardenedPHP takes care of all this.

Ensure application and server security by patching all PHP versions

PHP represents more than 79.2% of all server-side scripts. Because of this wide application usage, PHP is constantly exploited by hackers, making sites vulnerable.

HardenedPHP keeps your customers and servers safe by patching all PHP versions against known vulnerabilities - even those versions unsupported by the community.

Over 100 vulnerabilities, many of which were critical, have been discovered for the unsupported versions of PHP. All have been patched by CloudLinux.

Increase customer retention by not forcing upgrades to a newer PHP version

About 64,5% of all PHP sites use highly popular PHP 7 versions. Yet, these together with the 5th version (35% of all PHP websites) are unsupported by the community.

Developers write their scripts to accommodate a particular PHP version, but when a version becomes obsolete, companies are not always able to update and change programs to accommodate newer versions.

HardenedPHP patches old PHP versions so that you do not have to force your customers to re-write scripts written for an older PHP version or worse, risk breaking their sites.

Give your customers security and flexibility

PHP is universal and has the widest use of all server-side scripts. According to, as of April 2021, the percentage of websites using outdated PHP subversions of PHP 7.2 and earlier was as follows:

  • 27% PHP 7.2 — not supported by the community as of November 2020
  • 8,6% PHP 7.1 — no development, no bug fixes, no security support as of December 2019
  • 9,1% PHP 7.0 — not supported by the community as of January 2019
  • 35% older versions, including 5 and 4

With HardenedPHP in CloudLinux OS, not only can you secure old PHP versions, but you can also offer various packaged PHP versions on a single shared web server with PHP Selector to ensure maximum security and flexibility.
