BulletProof Security is a freemium WordPress security plug-in that can be activated and in use within minutes. Apart from the basics, the free plug-in can provide many functions not commonly seen in competing software. These include extensive HTTP and security logs, options to reveal hidden files left behind by other plug-ins, and database backup and manipulation tools. However, many of the freely available features are stripped of functionality. For example, the free plug-in is missing some alert functions that could notify a website owner of problems.

Pros & Cons

Pros

  • Pro version has a one-time cost, unlimited installs
  • Many automatic features

Cons

  • Free version isn't updated frequently
  • Limited support for both free and Pro versions

How We Chose the Best WordPress Security Plug-Ins

WordPress is used to create and manage millions of websites, and this makes it a prime target for hackers. However, its popularity has also spawned many tools to minimize possible harm. We created this list of the best WordPress security plug-ins of 2021 based on three main criteria: security features, reputation checks, and reporting capabilities.

Security Features

The most important features used to evaluate these WordPress security plug-ins include malware scanning and removal, DDoS protection, and web application firewall (WAF). We included or excluded certain plug-ins based on the ability to provide core functionality and whether these features are available in the free version.

Reputation Checks

Some of the best WordPress security plug-ins also provide reputation checks and monitoring. These tools focus on the reputation of a website itself, rather than a specific person or the company as a whole. For example, websites that send out a lot of emails need to monitor spam blacklists to make sure content is delivered at a high rate.

Reports

All the software on this list is capable of real-time monitoring but some are better than others at logging and reporting the security events they capture. We considered these reporting features to be very important when ranking the best WordPress security plug-ins because of their usefulness in finding vulnerabilities.
