Hardening & checklists
Practical hardening steps, audits, and security checklists that stick.
66 articles
Most WordPress security problems are not exotic zero-days. They are outdated plugins, debug mode left on, weak file permissions, unused themes sitting around, or XML-RPC and other endpoints left open for no reason. Hardening is the habit of closing those gaps before someone else finds them.
Checklists help because security work is easy to postpone. A short, repeatable pass after launches and updates beats a once-a-year panic. These articles walk through practical steps site owners and freelancers can actually finish, not a wall of theory.
WP Security Ninja includes 50+ security tests in the free plugin. They audit common weaknesses and explain why each finding matters, so you get a prioritized todo list instead of guessing. Pro adds active protection and selected fixes when you are ready to go further.
