Built for real-world WordPress security
Protection that is easy to use, but deep where it matters
WP Security Ninja helps you protect WordPress sites without turning security into a full-time job. Start with guided setup and practical defaults, then go deeper with malware scanning, file validation, vulnerability checks, login protection, firewall controls, audit logs, and agency-friendly deployment tools. Trusted since 2011 and designed for both site owners and professionals managing many installs.
Core protection
- Block bad traffic before it becomes a problem Filter malicious requests, block known bad IPs from a large cloud database, use country blocking, and stop bots probing fake URLs with 404 Guard. Advanced firewall controls also let you decide how blocked visitors are handled.
- Protect the login area from brute-force abuse Stop repeated failed logins, reduce username guessing, protect lost-password flows, and tighten access to one of the most targeted areas of any WordPress site.
- Add stronger login security with 2FA and hidden login URL Add two-factor authentication with authenticator apps or email codes, and rename the default login URL to reduce automated attacks.
- Find malware and suspicious code faster Scan plugins, themes, uploads, and other key areas for suspicious PHP and known malware patterns. Review flagged files safely, whitelist false positives, or remove what does not belong.
- Verify WordPress core files against official checksums Detect modified, missing, or unknown core files and compare them to the official WordPress version. Restore clean files when needed instead of guessing what changed.
- Check whether plugins have been tampered with Validate WordPress.org plugins against their official versions and inspect differences when files have changed, giving technical users real visibility instead of vague warnings.
- Catch vulnerable plugins, themes, and WordPress versions Compare installed software against an up-to-date vulnerability database with CVE and fixed-version data, so you know what needs patching before it becomes a bigger problem.
- Run 50+ security tests in one place Audit common WordPress security mistakes, weak settings, outdated software, and risky configuration issues in a single pass.
- Fix many common issues with a few clicks Apply one-click fixes for many security findings, with backups created before sensitive changes. You stay in control, but the routine hardening work gets much easier.
- Add extra protection for WooCommerce Protect login and registration flows, limit abusive checkout and add-to-cart activity, and reduce coupon brute-force attempts.
More than protection
Security tools that make WordPress easier to manage
WP Security Ninja does more than block attacks. It helps you monitor changes, stay informed, speed up routine work, and manage multiple sites more efficiently with practical tools for everyday WordPress security.
- Get protected faster with a guided setup wizard Start with a practical setup flow that helps new users run tests, enable recommended fixes, and turn on key protections without digging through every screen.
- Schedule scans and stay informed automatically Run regular scans in the background and get alerted when something changes, instead of relying on manual spot checks.
- Track what happened with a filterable events log See logins, scan activity, firewall events, updates, file actions, and more in one place when you need to investigate or document changes.
- See your security status at a glance The dashboard widget surfaces firewall status, updates, security score, and vulnerability findings without making you dig around the plugin.
- Reuse settings across sites Import and export settings to keep security policies consistent and speed up repeat deployments.
- Activate licenses across many sites with less manual work For bulk rollouts, you can include your key in a license_key.txt file inside the plugin package to automate license activation during deployment.
- White label the plugin for client sites Replace the plugin name, author, icon, URLs, and related branding with your own, and optionally hide it from the standard Plugins screen for a cleaner client experience.
- Connect security events to your workflow Send webhook events to Zapier or other systems that support webhooks for blocked visitors and login activity.
- Get support from the people behind the plugin Support comes from the team that built and works on Security Ninja, which matters when the question is not generic.

Amazing Amazing alternative to my past wp protection - great product and easy to use
Claire Oberwinter
Great plugin It is truly a great plugin that leaves me with a great feeling that finally my two sites that I'm running are pretty safe. One thing less in life I have to worry about!
This plugin is amazing If you’re in the WordPress game, WP Security Ninja is a total game-changer. Seriously, it’s like a secret weapon for developers. It’s so user-friendly, you’ll wonder why you didn’t snag it sooner. And let me tell you, I grabbed the Pro version, and man, no regrets whatsoever. It’s worth every single penny.
A very good and well thought tool!
patrickvieljeux
very good tool. simple and efficient. justwhat i needed.
Not only the plugin is of high quality… … but Support is even much better! Namely, I had one license issue/question which I was pretty sure it won’t be possible solving it. But Support did all in their powers (and more!) to solve our request, and at the end – they really did it (and it was also during the weekend). Amazing!
ap6y3jimm
Very effective protection. I tried different others like Wordfence, but settled on Security Ninja this is my choice has been working stably for several months. And I can see from the logs how he is waging a quiet war with attacks. A good balance between functionality and management.
kelliclaypool
Easy to Use Plugin I’ve used several security plugins and services and have found Security Ninja to be easy to install, easy to configure, great documentation, and easy to use. I’ve added this plugin to my “must use” list to install on all sites that I develop/design.
ffriedrich
works ;- works like expected with many features. Like it!
Thank you very much. It is a great plugin you have, keep up the great work.
I've tried most of the security plugins out there. Some are good but Security Ninja beats them all! Easy (like in REALLY easy) setup, comprehensive protection and perfect access to log files. My absolute recommendation!

Complete WordPress Site Protection
Security Ninja has protected websites since 2011!
Is WordPress Secure?
WordPress is a reliable platform, but no system is completely secure. While the core WordPress software is well-built, vulnerabilities can arise when you install themes or plugins. These add-ons, while essential for customizing your site and adding features, can create security gaps that attackers exploit.
Why Do You Need Extra Protection?
Every website, no matter how small, is at risk. Automated bots constantly scan millions of websites, looking for weak points. These bots don't target sites based on popularity or revenue. Instead, they exploit any vulnerability they find, whether it's a business website, blog, or personal portfolio.
Themes and Plugins: A Hidden Risk
When you install a theme or plugin, you bring more than functionality to your site. Poorly coded themes or outdated plugins can open doors for hackers. Even premium plugins and themes sometimes use third-party code that hasn't been updated or secured properly.
The truth is, most website owners don't have the time or expertise to review every line of code in a theme or plugin. This leaves your site exposed to risks beyond your control.
Why Install a Security Plugin?
- Real-Time Protection
24/7 monitoring and threat detection
- Vulnerability Scanning
Identifies security gaps before hackers do
- Automated Defense
Blocks attacks without manual intervention
Why Small WordPress Sites Are Big Targets for Hackers
Many WordPress users believe only high-traffic or eCommerce websites are at risk. But the truth is, small WordPress websites are often the easiest targets.
Hackers and bots constantly scan for vulnerable websites, and smaller sites are more likely to lack strong security plugins or updates. Once compromised, attackers can use your site to:
- Speed Malware
Infect your visitors with malicious software
- Host Phishing
Create fake login pages and scams
- Launch Attacks
Use your server to attack other websites
No matter the size or type of your website, proactive protection is critical. That’s where Security Ninja steps in.
Complete WordPress Security – Made Simple
Many WordPress users believe only high-traffic or eCommerce websites are at risk. But the truth is, small WordPress websites are often the easiest targets.

- Scan core WordPress files for unauthorized changes
- Block brute-force login attempts and known malicious IPs

Core File Scanner: Protect What Runs Your Website
Your WordPress core files are the backbone of your site, and hackers know it. If these files are tampered with, your entire site is at risk.

You'll have full control:

Why WordPress Security Is Essential (Even for Small Sites)

Common Threats to Your WordPress Site:
- Brute-force attacks:

Hidden scripts from theme/plugin vulnerabilities - Cross-site scripting (XSS):
Dangerous input through comment forms - SQL injections:
Exploits targeting unsecured databases

Recent releases
Release history
- 2026-09-08
- Visitor IP detection - Choose how the firewall reads the visitor IP: Automatic, Cloudflare, proxy headers, or REMOTE_ADDR. Automatic trusts Cloudflare ranges by default. For another load balancer or reverse proxy, add its IPs under Trusted proxy CIDRs. Free and Pro.
- Vulnerability Scanner - Scheduled warning emails wait for a finished scan, skip plugins and themes that are gone or already patched, and do not repeat the same findings within 24 hours. Thank you Jamie.
- Deactivation - One central "Remove settings when deactivating" switch. Leave it off to keep settings, scans, logs, and cached files. Scheduled jobs still stop when the plugin is deactivated.
- Uninstall - Removing the plugin also clears module tables, settings, cached files, and related user metadata.
- Events Logger - Administrator emails now cover new accounts and role promotions.
- Events Logger - Speed improvement - When logging is off, event hooks and database writes are skipped. Broad REST API error logging stays off by default; turn it on in Events settings if you need those diagnostics.
- Settings import/export and MainWP - Events REST logging and visitor IP settings, including trusted proxy CIDRs, are included when you copy settings between sites.
- Malware Scanner - Removed the unused legacy scanner.
- MainWP - Applying settings remotely now reschedules the scanner cron when the schedule changes, and applies the same wp-config updates as the Fixes page (file editor, debug, secure cookies).
- MainWP - Remote settings now include WooCommerce rate-limit numbers, 2FA grace period and login copy, and satellite/ASN soft-mode lists.
- Frontend - Speed improvement - Premium no longer loads unused Pro modules on public page views. Free modules are unchanged. Thank you Jose.

- 2026-09-01
- Firewall - Per-visitor reverse-DNS, ASN, and GeoIP caches no longer fill the WordPress options table with one row per IP. On busy sites without Redis/Memcached that could grow to hundreds of thousands of rows and cause intermittent downtime. After update, leftover rows are removed automatically in small batches. Thank you Davina.
- Firewall - Search-engine and crawler checks only run reverse-DNS when the User-Agent looks like a known crawler. Normal browser traffic no longer triggers a DNS lookup on every page view. AI crawlers (OpenAI, Perplexity, Claude) are checked against published IP ranges only.
- Firewall - Hostname-based "blocked hosts" matching (part of Filter Suspicious Queries) is off by default. URI, query string, user agent, and referrer rules still run. Developers can re-enable hostname checks with the secnin_cf_check_blocked_hosts filter.
- Firewall - Satellite/ASN softening (Pro) no longer calls the remote ASN API on every miss when the site has no object cache. With Redis or Memcached, results are cached there instead of in the database.
- Firewall - The list of remembered validated crawler IPs is limited to 200 entries so it cannot grow without bound.
- Fixes - Disable Username Enumeration now blocks anonymous REST user listing (/wp/v2/users and ?rest_route=), not only by removing the endpoint. The username enumeration security test checks that path as well. Thank you Elias.
View changelog
- 2026-08-14
- Compatibility - Removed a chillerlan Settings class_alias that broke LatePoint (and similar) booking confirmation QR codes after the 5.294 Imposter isolation fix. Thank you Daniel.
- MainWP - Copying Malware Scanner whitelist settings now keeps filename, hash, and pattern entries instead of flattening them into strings the scanner ignores.
- Core Scanner - Deactivating the plugin on a Multisite subsite no longer deletes network-wide scan results, ignore lists, or the main-site daily scan schedule.
- MainWP - Malware whitelist path sanitization now accepts the stored `filename` field when settings are copied between sites.
- Security headers - Default Referrer-Policy is now strict-origin-when-cross-origin (browser-aligned; better embed compatibility). Existing saved settings are not changed. Thank you Heath.
- MainWP - Remote vulnerability refreshes now return clear scheduled, already-pending, unavailable, and scheduling-failed responses.
- MainWP - Remote settings apply accepts blocked-country lists, Malware Scanner whitelist paths, and Core Scanner ignore paths with Security Ninja for MainWP 2.2.0+.
- MainWP - Added the remote `update_vulnerabilities` action for free and Pro sites. It schedules a dedicated one-off database refresh even when the normal daily or weekly vulnerability job already exists.
