Essential WordPress Security Tips for 2025
WordPress powers 43% of the web, making it the most targeted CMS by attackers. These security measures every WordPress site owner must implement — many take under 10 minutes.

Harden Your Login Page
Change the default /wp-admin login URL, enable two-factor authentication with a plugin like WP 2FA, and implement login attempt limits. These three steps alone block the vast majority of automated brute force attacks targeting WordPress sites.
Keep WordPress, Themes, and Plugins Updated
Security patches are the primary reason for WordPress core and plugin updates. Enable automatic minor updates for WordPress core, review and apply plugin updates weekly, and remove any plugins or themes that are no longer actively maintained.
Set Correct File Permissions
WordPress directories should be at 755 and files at 644. The wp-config.php file should be 600 — readable only by the owner. Overly permissive file permissions are a common vector for attackers to inject malicious code into your WordPress installation.
Install a Security Plugin and Monitor
Wordfence or Sucuri Security provides real-time malware scanning, a web application firewall, file integrity monitoring, and security notifications. Pair this with daily offsite backups and you have a defence-in-depth posture appropriate for most WordPress sites.
