Why is WordPress security critical?
WordPress powers 43% of all websites on the internet. That makes it one of the most common targets for hackers. The good news: 95% of attacks can be prevented with basic security measures at the start of a project.
1. Choose quality hosting
Shared hosting for 50 CZK per month means shared risk. We recommend managed WordPress hosting (Raidboxes, Kinsta, WP Engine) or a VPS with custom configuration. A server-level firewall stops most attacks before they even reach WordPress.
2. Strong passwords and 2FA
The most common attack vector is weak passwords. Rules:
- Admin password at least 16 characters, generated securely
- Separate unique passwords for FTP, the database, and the hosting panel
- 2FA for all admin accounts (Wordfence, WP 2FA)
- Change the default username “admin” to something unique
3. Updates: the foundation of security
90% of hacked websites used an outdated WordPress version, plugin, or theme. Set up automatic updates for minor versions and security patches. Test major updates in a staging environment.
Fewer plugins means a smaller attack surface. Every plugin is a potential vulnerability. Remove everything you do not use.
4. Security plugin
Install at least one: Wordfence (firewall + malware scanner), Sucuri (cloud WAF), or iThemes Security (hardening). Activate login attempt limits, IP blocking, and file change detection.
5. Backups — your safety net
A backup you do not have will not save you. Set up daily automatic backups through UpdraftPlus or server cron. Store backups outside the server (Google Drive, S3). Test backup restoration at least once per quarter.
6. WordPress hardening
- Disable file editing from the admin panel:
define('DISALLOW_FILE_EDIT', true); - Change the database prefix from the default
wp_ - Hide the WordPress version in HTML
- Disable XML-RPC if you do not use it
- Set proper file permissions (644 for files, 755 for directories)
- Add security headers through .htaccess
7. SSL certificate
In 2026, this is already a basic standard, but we still find company websites without HTTPS. Let’s Encrypt is free. Enable forced HTTPS redirect and the HSTS header.
Conclusion
WordPress security is not a one-time task — it is an ongoing process. But these 7 steps at the start will protect you from 95% of attacks. Need help securing your website? Get in touch with us.
