Which CMS to choose for a site with private access by subscription?

Question

CMS

1. Actually, the functionality of the site will be based on the possibility of providing access to the closed section of the site on a paid basis. That is, a person pays, relatively speaking, access for a month, and for a month he will have the opportunity to visit a closed section.
2. The reliability and security of the site is very important. I focus on this first of all,
I consider both paid and free CMS. Among others, WordPress, Joomla, Drupal and 1C Bitrix stand out so far. Thanks for your advice!

Answer 1

This is what I put together on WordPress.
The security of WP depends on the curvature of the code. I have over 50 sites on it and not one has ever been infected or hacked.
