WordPress Security Guide: What to Do Before You Get Hacked (2026)

Why Is WordPress Targeted?

WordPress powers 43% of the internet — and that very popularity makes it the #1 target for hackers. A WordPress site faces an average of 90,000 attack attempts per day. 41% of attacks exploit plugin vulnerabilities, while 29% are brute force password attempts.

Essential WordPress Security Checklist

1. Strong Login Security

• Change the default "admin" username.
• Use passwords with at least 16 characters including uppercase, lowercase, numbers and symbols.
• Enable two-factor authentication (2FA) with Google Authenticator or Authy.
• Limit login attempts: use Limit Login Attempts Reloaded to temporarily block IPs after 3 failed attempts.

2. Keep Everything Updated

Security patches for WordPress core, themes and plugins are released regularly. An unpatched plugin is an open door for attackers. Enable auto-updates or check weekly at minimum.

3. Security Plugins

Wordfence: Firewall, malware scanning, and login security. Sucuri: CDN-based WAF that blocks attacks before they reach your server. iThemes Security: File change detection and database backup features.

Server-Level Security

• SSL Certificate: Encrypt all traffic. Check your SSL with our SSL Checker.
• PHP Version: Use PHP 8.2+; older versions contain known vulnerabilities.
• wp-config.php Protection: Block external access to this file via .htaccess.
• Disable XML-RPC: Block access to xmlrpc.php if you don't use it — it's frequently exploited for DDoS and brute force attacks.

FAQ

Is WordPress insecure?

No, WordPress core is secure. The vast majority of security issues stem from outdated plugins, weak passwords, and low-quality hosting. When properly configured, WordPress can be an enterprise-grade secure platform.
