What is Kadence Security?

Kadence Security is a WordPress security plugin that protects sites from brute force attacks, malware, and login vulnerabilities. Formerly known as iThemes Security, it is now developed by Nexcess. The plugin has been actively maintained for 16 years, making it one of the oldest security solutions in the WordPress ecosystem. It currently has over 700,000 active installs and a 4.6 out of 5 rating from 3,987 user reviews. A full 86% of those reviews are five-star, indicating strong user satisfaction across a vast install base.

The plugin reduces your site’s risk by automatically locking out malicious users identified by a Brute Force Protection Network of nearly 1 million sites. It focuses on the most attacked part of WordPress: user login authentication. With a Pro upgrade, Patchstack integration provides protection before a plugin or theme vulnerability is even patched. This creates a 24/7/365 security layer for your website.

  • Malware Protection: Scans for and helps remove malicious code that could harm your site or visitors.
  • Onboarding Wizard: Guides any user through securing their site in under 10 minutes, regardless of technical skill.

Who Should Use Kadence Security?

Kadence Security is built for site owners who want a hands-on yet guided approach to security. The plugin’s six Site Templates make it ideal for beginners running eCommerce stores, community networks, or simple blogs. You do not need to be a developer. The 10-minute setup wizard walks you through each decision. With 700,000+ active installs, it is trusted by both small site owners and larger organizations managing multiple sites.

Advanced users will appreciate the real-time dashboard and Patchstack integration in the Pro version. The plugin requires a minimum of WordPress 6.5 and PHP 7.4. It works on Apache, LiteSpeed, or NGINX servers. If you manage a site that needs proactive brute force blocking and user authentication security, this plugin fits your workflow. The 86% five-star rating confirms it meets expectations for a wide range of site types.

Installation & Setup

Install Kadence Security from your WordPress admin dashboard like any other plugin. The onboarding wizard activates immediately, letting you choose a Security Site Template based on your site type. The entire process takes under 10 minutes, even for non-technical users. The plugin strongly recommends a full site backup before activation, as it makes changes to your database and site files.

Support & Community

Support data from the last 2 months shows 24 open threads and only 6 resolved, giving a 39% resolution rate. This is notably low compared to the plugin’s high rating. The 7% one-star reviews often cite failed backups or site breakage after applying security settings. The FAQ itself warns users to back up before using the plugin. The development team tests only on the latest stable WordPress version, which can cause issues for sites not fully updated. Despite these support challenges, the plugin remains popular due to its proven track record over 16 years and its large, active user base of over 700,000 sites.
