★★★★★

Works well as a base security plugin

“WP Security Ninja stands out with a balanced and clear mix of features. It works well as an all-in-one solution but remains simple enough to combine with tools like Patchstack without feeling overwhelming.”

★★★★★

Upgrade FAQ

What’s the difference between Free and Pro?+

Free gives you visibility and hardening basics - firewall ruleset, vulnerability checks, 50+ security tests, core integrity, and a security score. Pro adds active protection: cloud bad-IP blocking, malware scanning, login protection and 2FA, one-click fixes, scheduled scans, a full events logger, and priority support.

How does the 14-day free trial work?+

Start a free trial with the same site count you plan to buy. You get full Pro features for 14 days. If you continue, billing starts after the trial; cancel anytime before then and you will not be charged.

Can I use Security Ninja Pro on multiple sites?+

Yes. One Pro license covers the number of sites you choose at checkout, from a single site up to unlimited. Pick the site count that matches your portfolio; you can upgrade later if you add more sites.

Can I cancel my subscription anytime?+

Yes. Cancel renewal anytime from your account. You keep Pro access until the end of the current billing period.

What is covered by the money-back guarantee?+

Within 30 days of purchase, if an issue makes the plugin unusable and we cannot fix it, we will refund you in full. We may ask what went wrong so we can improve, your refund still goes through either way. Contact support through your Freemius account or our help desk.
