Protect Your Site Using the Best Security Plugins Available

Updated October 12, 2020

There are hundreds of WordPress security plugins to choose from, with some trying to do one thing only and others trying to do it all. Given the fact that security plugins will often make fundamental changes to folder locations, database prefixes, user ID’s and enumeration, obfuscate file locations and restrict login access, it’s always prudent to make a backup and look at plugins which are:

       – Well rated on
       – Have a substantial number of active installations
       – Are known for including great customer support
       – Robust in free versions and even more powerful in paid versions (if needed)

Some plugins focus on firewall, malware, file integrity, scanning, monitoring or locking down access. Some do all those things. However, none offer the full range of features (cumulative) found in the top 6 best WordPress security plugins. Choose any one of them, make a backup, then follow the install instructions.

Advice on choosing a security plugin – try the free version before buying a paid version!

Support Differences

With free security plugins, you’ll often get directed to a forum where you can post a question and hope for help. Paid versions often include email and live chat support. Telephone support is incredibly rare for plugins, security and otherwise.

Internal (Local) vs Cloud (Remote) Differences

Many cloud-based malware scanners are limited to testing what they see presented to a simulated web browser, so they wouldn’t be able to detect at the same level as a scan running on the server where the WordPress site is hosted.

Some cloud-based Web Application Firewalls (WAF) can be bypassed unless restrictive techniques are employed to limit access.

Premium vs Free Feature List Differences

There is no hard and fast rule as to which features come with the free version of plugins and which features will require premium upgrades. Suffice it to say that the security plugins listed are very powerful, even in their free versions, but you should check on premium upgrades to see what else can be had and at what price.

Malware Detection vs Detection + Removal

Detection is one thing, but removal or file restoration is quite another. Many free plugins will check for malware and alert you if there’s a problem, but it’s mostly paid versions that offer the quick and easy removal feature.

Multiple Plugins Working Together

Not all security plugins can be installed together, simultaneously, mostly because the scans and checks they do can be seen as attacks by other plugins. For example, WordFence will likely detect Sucuri Scanner as an invalid crawler and will stop Sucuri from performing basic functions, unless the Sucuri IP address is whitelisted within WordFence.

Operating Environment Requirements

Be sure to check the installation requirements before making a decision and trying to install a security plugin or plugins.
       – CPU – vCPU Cores Available
       – Sites – Single, Multi-Site, Network
       – RAM – Minimum MB of Available Memory
       – Web Server – Apache, LiteSpeed (mod_rewrite?), NGINX


Always make a backup of your entire site and database before installing a security plugin that might make massive changes to your file paths, database or other critical parts of the website / hosting account.

Try the free version before splashing out cash on a paid version. See if you like the look and feel, features, notifications and ease of management. It pays to spend a little time testing and evaluating. After all, there are reasons why there are multiple competing plugins in the market that are all high quality and popular. It’s because each one fits a slightly different user preference. Try out one. try out several (not all at once) and decide for yourself which one is preferred.


There’s no absolute top choice among this field. You’d do well to install any of them as compared to doing nothing!

If you have the time and inclination, you could install other plugins that each perform one or two of the features that these behemoths have in their repertoire. Slice and dice the features that you want, or think you need, and create your own solution.

These mega-security plugins for WordPress are built to give users the convenience of having a laundry list of security features all in one place. It’s less work than installing, updating and testing a dozen other smaller plugins (making sure they all work well together).

The list of plugins here has been narrowed from hundreds based on features, support, regular updates, reviews and prior experience in hands-on testing.
