Security Ninja – WordPress Security & Firewall

79 Quality Score

Active Installs

17/30

With only 7,000 active installs it is a niche player, well behind the leading alternatives, which is why the raw popularity signal is modest even after the boost.

Update Freshness

25/25

The plugin was last updated in June 2026 and clearly remains an active project, earning a perfect maintenance score.

User Rating

14/15

99 users have rated it 92/100, which is a strong vote of confidence from the small pool of users who have tried it.

Support Health

8/15

Zero support threads and zero resolved tickets is a red flag, either the plugin is so stable nobody needs help or support channels are not being used, and the scoring treats it as average at best.

WP Compatibility

15/15

Tested up to WordPress 7.0 with a minimum requirement of 4.7 and PHP 7.4, giving it a perfect compatibility score across modern and slightly older installs.

What It Does

Security Ninja scans your WordPress site with 50+ security tests, checks for vulnerabilities in your core, themes, and plugins, and ships with a free 8G firewall (WAF) plus an event logger to track suspicious activity on your site. It also includes an AI-powered security repository feature to help identify weak points across your install.

Who It's For

This plugin fits small businesses, bloggers, e-commerce shops, and agencies running client sites who want an all-in-one security tool without paying for a premium tier upfront. It is especially useful for multisite operators and sites handling customer data that need a WAF included at no extra cost.

Who Should Skip It

If you already run Wordfence, Really Simple Security, or Jetpack on your site, stacking Security Ninja is redundant and adds load to your server. Enterprise teams with dedicated security staff or compliance officers will likely find the feature set too lightweight compared to paid offerings.

The Bottom Line

Security Ninja offers a generous feature set for its size, including a free WAF and vulnerability scanner, and it scores 78.52/100 overall, but the tiny install base and absent support traffic make it a higher-trust bet for tinkerers than for sites where downtime is costly. If you value community proof, the alternatives listed below are safer choices; if you want a lightweight, actively maintained bundle that does not nickel-and-dime you, Security Ninja is worth a test drive on a staging site first.

Pick Really Simple Security if your main concern is HTTPS, SSL migration, and a clean hardening layer across millions of installs.

Wordfence Security – Firewall, Malware Scan, and Login Security 97/100

Choose Wordfence if you want the largest install base (5 million plus) and a mature malware scanning engine with a well-known threat feed.

Jetpack – WP Security, Backup, Speed, & Growth 94/100

Pick Jetpack if you also want backups, performance, and growth tools bundled with security from a well-known vendor.

All-In-One Security (AIOS) – Security and Firewall 91/100

Choose AIOS if you prefer a completely free, well-established option with one million installs and a built-in firewall.

Safe SVG 89/100

Safe SVG is a single-purpose tool, pick it only if your specific need is sanitising SVG uploads rather than general site security.
