Best Security Plugins for WordPress

Millions of websites use WordPress for publishing their content, which makes the platform a target for hacking. Its open-source nature exposes the WordPress core code to thousands of viewers, which sounds problematic, but it allows very rapid discovery and correction of vulnerabilities.

WordPress also pushes updates to patch known vulnerabilities. Still, third-party plugins and themes expose WordPress (and even the whole server) to hacking. First, understand these and other ways your site can be attacked. Then, use the information below to help you decide which security plugins you need.

Why Website Security is Important

Small businesses are targeted by hackers as often as are large corporations, and disregarding website security invites costly consequences for both. A business's website is frequently the first point of contact with prospective customers. An unsecured site can lead to income loss and damage to your brand. Hackers strive to gain control of a website in order to read, modify, and make changes to files and databases, usually for purposes of stealing data, such as site visitors' email addresses, other contact information, credit card details and other information of value.

Website security threats are always adapting and evolving to keep pace with security innovations. Securing your site requires employing some tools and techniques to ensure that data on your site cannot be accessed and manipulated by a human hacker, bot or botnet without the correct permissions. A secure Content Management System (CMS) such as WordPress provides site owners a good start toward web security, and security add-ons add more layers of protections.

WordPress Security Plugin Essentials

Some plugin solutions offer a wide array of anti-hacking features to combat attacks by brute-force, malware, exploits, and many other threats. Others are designed to do one particular job especially well. So, you may need to combine multiple plugins, in order to achieve the best available coverage. Keep in mind these few primary considerations when considering WordPress security plugins:

Updates — How recently was plugin last updated, and is it being updated regularly?
Support — Do the plugin developers, or others, provide user support, if needed?
Downloads — How widely is the plugin used?
Reviews — Overall, are the plugin users well satisfied with the plugin's performance?
