WordPress is the world's most popular CMS platform and powers over 40% of all websites. That popularity makes it a primary target for automated attacks, bots, ransomware campaigns and data theft attempts.
The good news is that most successful breaches don't happen because of WordPress itself, but because of poor configuration, outdated plugins, weak passwords and lack of maintenance.
This guide brings together the best WordPress security practices for 2026 and can serve as a checklist for every site owner.

Why WordPress sites become attack targets
The most common reasons include:
- ✓Outdated plugins and themes
- ✓Compromised passwords and no 2FA
- ✓Vulnerable contact forms
- ✓Incorrect file permissions
- ✓Low-quality hosting and no monitoring
Hackers rarely attack a specific site manually. In most cases, automated bots scan thousands of sites at once.
Keep WordPress always up to date
Updates contain not only new features but also critical security patches.
What you should update
- ✓WordPress Core, themes and plugins
- ✓PHP version
- ✓MySQL / MariaDB
Best practices
- ✓Enable automatic updates
- ✓Remove unused plugins
- ✓Use a staging environment before major updates
Use strong passwords
Weak passwords remain one of the leading causes of compromised sites.
Requirements
- ✓Minimum 16 characters
- ✓Upper and lowercase letters, numbers and special characters
- ✓Unique password for every account
Use a password manager such as Bitwarden or 1Password.
Enable two-factor authentication
Even if the password is compromised, the second factor blocks access.
Recommended solutions: WP 2FA · Wordfence Login Security · Google Authenticator
Protect the login page
- ✓Limit login attempts — block IP addresses after several failed attempts
- ✓Change the login URL — use WPS Hide Login
- ✓CAPTCHA — add Google reCAPTCHA to login forms
Use a Web Application Firewall
A WAF is the first line of defence.
Cloudflare
DDoS protection · Rate Limiting · Bot Protection · CDN
Wordfence
Malware Scan · Login Security · Threat Intelligence
Sucuri
Suitable for business sites and online stores
HTTPS and SSL
HTTPS is a mandatory standard.
- ✓Data encryption
- ✓Increased trust and SEO advantage
- ✓Protection against MITM attacks
Use Let's Encrypt or a Premium SSL certificate.
Correct file permissions
Recommended settings:
| Type | Permissions |
|---|---|
| Files | 644 |
| Directories | 755 |
| wp-config.php | 600 or 640 |
Incorrect permissions can open serious vulnerabilities.
Protect wp-config.php
This file contains the most critical information.
Add extra protection via .htaccess or Nginx rules.
Also disable file editing:
define('DISALLOW_FILE_EDIT', true);Backup strategy
The best protection is the ability to recover quickly.
3-2-1 rule
- ✓3 copies
- ✓2 different media
- ✓1 offsite copy
Recommended tools: UpdraftPlus · BlogVault · Jetpack Backup
Malware scanning
Regular scanning enables early threat detection.
Use: Wordfence Scan · Sucuri Scanner · VirusTotal
Monitoring and logs
Track:
- ✓Failed logins and new users
- ✓File Changes and Plugin Updates
- ✓Suspicious Traffic
Recommended tool: WP Activity Log
OWASP Top 10 and WordPress
Modern WordPress security should cover the main OWASP risks:
- ✓Broken Access Control
- ✓Cryptographic Failures
- ✓Injection Attacks
- ✓Security Misconfiguration
- ✓Vulnerable Components
Regular Security Audits identify such issues before they can be exploited.
Protecting WooCommerce stores
Online stores require additional measures:
- ✓Enhanced payment protection
- ✓PCI DSS compliance
- ✓Restricted access to admin panels
- ✓Additional monitoring
How to tell if your site has been hacked
- Unexpected redirects
- Spam pages
- Unknown administrators
- Sharp drop in SEO traffic
- Warnings from Google
What to do if compromised
- Isolate the site.
- Change all passwords.
- Scan the system.
- Restore from backup.
- Analyse the logs.
- Fix the root cause of the breach.
Wordfence vs Sucuri vs Cloudflare

The best results come from combining them.
