What Exactly is a Joomla Firewall and Security Extension?

Joomla is a CMS-driven site builder and hosting platform that is considered by experts to be an excellent alternative to WordPress which has long been the CMS editor of choice of many site owners across the globe.

As with WordPress and other platforms, a Joomla firewall and security extension is an application built into the platform or a third-party Joomla security plugin. Specifically, it is voluntarily installed by the site owner or manager to protect their sites from the infiltration of malware or forcible entry by hackers. This is achieved through Joomla security plugin's real-time monitoring and features geared towards identifying and purging threats.

How We Chose the Best Joomla Security Extension and Joomla Firewall:

Ideally, a combination Joomla firewall + best Joomla security plugin should include the following protective, preventive, and curative features. In addition, it must be able to execute Joomla security best practices. Therefore, the criteria for choosing the best security extensions for Joomla are:

  • Backend passwords;
  • Scanning done by the best Joomla firewall/best Joomla security plugin is on a regular, real-time basis. This is to identify threats, ensure system integrity, and prevent permission errors within the system;
  • Joomla firewall and Jooma security extensions can protect against brute force attacks. Specifically, this includes but is not necessarily limited to limitations for login attempts, monitoring of all login activities, as well as management of password use;
  • The best Joomla firewall and Joomla security plugins keep a regularly updated malware database;

Securitycheck’s core extension is downloadable for free, while the all-in package for Securitycheck Pro will set you back by $120 per year; Individual features range from $9.00 to $50 annually; Securitycheck Pro J25 for Joomla 2.5 costs $9.95 per year, but do take note that it will lack some features already included in the current releases.
