Description

Security Ninja helps you identify vulnerabilities and harden the security of your WordPress websites. Paired with MainWP, you can now manage and monitor all your connected sites from one central location.

This MainWP extension brings Security Ninja into your MainWP dashboard so you can manage and monitor all connected sites from one place.

Free version: Run Security Ninja’s Security Tests and Core Scanner remotely on one or more child sites. View results for all connected sites: vulnerabilities (plugins and themes), Security Tests table, Core Scanner summary, and Malware Scanner summary (last run and count when scans are available on the child site). The Security Ninja column in the MainWP Sites table shows test score and vulnerability count. The extension main page includes an All Events tab (with a Pro upsell message for free users) and a Settings tab.

Pro version: Everything in Free, plus: remote Malware Scanner (included when you use “Run all security scans” or dedicated malware scan actions, on Pro child sites); unified events log with filters and search; full malware scan file list on the per-site tab; White Label bulk action to manage child site settings; Update database tables (bulk and per-site); Pro Reports tokens for Security Ninja data. Event logs and full malware details require Security Ninja Pro on child sites.

Note:
To view event logs and scan data, your child sites must have Security Ninja Pro installed. You can still monitor free sites from the MainWP dashboard, but features like event logging only work if those sites also have premium features enabled. The “Update database tables” action requires Security Ninja 5.271 or newer on the child site.

This extension helps you save time, stay in control, and manage security across all your sites—whether you’re handling a handful or hundreds.

MainWP is an invaluable tool for those who manage multiple WordPress websites.

To combine the two, you need to install this extension on your master MainWP website.

FAQ

What does “Run all security scans” do?: It triggers a full security run on the selected child site(s). In the free version, this runs Security Ninja Security Tests and Core Scanner. In the Pro version (with Security Ninja Pro on the child sites), it also runs the Malware Scanner. The scan runs regardless of the Scheduler setting on the child site. After it finishes, sync the site(s) again in MainWP to see updated results (scores, vulnerabilities, scan data) in the dashboard.
Support and Documentation: Please refer to our documentation pages for help and technical information on Security Ninja and the integration with MainWP.

I recently purchased a lifetime license for both the Security Ninja plugin and the Security Ninja for MainWP plugin. Both are working flawlessly. Lars Koudal was very helpful in helping me troubleshoot an issue. So their support is on-point. 10/10. Would buy again.
