Security testing is a core feature in Security Ninja free and Pro that checks your website for settings that could be dangerous to your website and expose yourself to hack attempts.
The tests range from ways to prevent your website from being detected, to default settings that could make your site vulnerable to various types of cyber attacks. These include SQL injection, cross-site scripting (XSS), and brute-force attacks, among others.
In the free version, basic checks are performed, such as ensuring that your WordPress version is not publicly displayed, or that your admin login page is not easily guessable. These checks aim to cover the most common vulnerabilities that hackers exploit.
The Pro version takes it a step further by offering advanced features like real-time monitoring, firewall protection, and even automated backups.
