Frequently Asked Questions

Common questions about Security Ninja – WordPress Security & Firewall

Yes. Security Ninja includes a basic Web Application Firewall (WAF) for free, based on the 8G ruleset. It blocks common malicious requests and reduces bot noise.

Pro includes login brute-force protection (failed-login limits), rename login, and 2FA. The free version records login attempts (successful/failed) in the Events Logger and runs security tests that check password strength-it does not block repeated failed logins on its own.

Yes. The Vulnerability Scanner is fully available in the free version and helps you identify known vulnerabilities in plugins/themes so you can patch quickly.

Site owners, agencies, and developers who want a lightweight WordPress security plugin to harden sites and catch problems early.

In normal operation, no. Some scans can temporarily use more resources while they run.

Security Ninja runs checks and shows recommendations. Some Pro features can add active protection layers (firewall/WAF controls, login protection), which you can configure.
