Snuffleupagus (https://snuffleupagus.readthedocs.io) is a PHP7+ module designed to drastically raise the cost of attacks against websites. This is achieved by killing entire bug classes and providing a powerful virtual-patching system, allowing the administrator to fix specific vulnerabilities without having to touch the PHP code.

This will help to make the PHP more secure since there's no suhosin for PHP7.2 and superior versions.
