WordPress isn’t just the most popular content management system in the world - it’s also one of the most frequently attacked. From automated bot attacks to targeted vulnerabilities in plugins, the threat landscape keeps growing. Protecting your website matters more than ever in 2025 - attacks are getting more sophisticated, GDPR requirements stricter, and downtime more expensive.
Why does WordPress security matter so much?
With over 43% market share, WordPress is the most widely used CMS in the world - and at the same time one of the most popular targets for cybercriminals. More than 90,000 hacking attempts happen against WordPress sites every day (source: Wordfence).
Many people think: “That doesn’t apply to me - my site is too small.” Wrong. Most attacks happen automatically via bots. Victims aren’t hand-picked - they’re found by scanning for vulnerabilities.
Possible consequences without protection:
- Website downtime
- Loss of sensitive customer data
- Malware infections
- SEO penalties from Google
- Legal warnings for GDPR violations
The 10 most important measures for maximum WordPress security
1. Use strong passwords & two-factor authentication
- At least 16 characters with numbers, special characters, and mixed case
- Use a password manager like Bitwarden or 1Password
- Enable 2FA (e.g. via the WP 2FA plugin)
2. Keep WordPress core, plugins & themes up to date
Over 50% of all successful WordPress hacks come from outdated software.
- Weekly updates of WordPress core
- Updates for all installed plugins and themes
- Avoid plugins that haven’t been updated in over 12 months
3. Only use reputable plugins and themes
Only install extensions from trustworthy sources. Look for:
- Last update < 6 months ago
- Ratings > 4 stars
- Active installs > 10,000
- Compatibility with your WordPress version
4. Secure your login page
- Change the login path with WPS Hide Login
- Limit login attempts (e.g. “Limit Login Attempts Reloaded”)
- Enable Google reCAPTCHA on login
5. Install a web application firewall (WAF)
Recommended solutions:
- Wordfence: all-in-one with a scan engine and live traffic analysis
- Sucuri Security: cloud-based firewall with CDN and malware cleanup
- iThemes Security Pro: with hardening options and login monitoring
6. Enable automatic backups
At least one full backup (files + database) daily.
Recommended plugins:
- UpdraftPlus: simple, reliable, many storage destinations (Dropbox, Google Drive, etc.)
- BlogVault: premium tool with one-click restore
- ManageWP: centralized management
7. Use SSL certificates & HTTPS
SSL certificates encrypt data transmission. Google has required SSL as a ranking factor since 2018.
- Free with most hosts via Let’s Encrypt
- Enforce redirection via “Really Simple SSL” or via .htaccess
8. Disable XML-RPC (if not needed)
XML-RPC is an old interface, frequently targeted by brute-force attacks. Remove it with the “Disable XML-RPC” plugin or in your .htaccess file.
9. Protect file permissions and wp-config.php
- Set correct file permissions (644 for files, 755 for folders)
- Lock down wp-config.php via .htaccess:
<Files wp-config.php>
order allow,deny
deny from all
</Files>10. Use monitoring tools & detect attacks early
- UptimeRobot - offline notifications
- WP Security Audit Log - logs all activity
- Sucuri SiteCheck - malware scanning
