How to Secure Your WordPress Website: Complete Security Checklist

WordPress powers 43% of the web, making it the #1 target for automated attacks. Every day, bots scan millions of WordPress sites looking for vulnerabilities. Without proper security, it's not a matter of if your site will be attacked — it's when.

This checklist covers 25 essential security measures organized by priority.

Priority 1: Critical (Do Immediately)

1. Update Everything

• WordPress core updated to latest version

3. SSL Certificate
