The Ultimate WordPress Security Checklist for 2025

WordPress powers over 40% of websites globally, including thousands of online businesses in Nepal. But with popularity comes risk. In 2025, WordPress sites will be a top target for hackers, bots, and automated attacks.

From stolen data to site blacklists, the damage from a hacked site can be brutal.

This guide simplifies WordPress security for anyone who’s running or thinking of running their sites with WordPress, including practical steps anyone can follow to lock down their website before disaster strikes.

Why WordPress Security Matters More Than Ever

The threat landscape has changed. It’s no longer just about weak passwords.

🤖 AI-powered brute force attacks can guess logins faster than ever
🔌 Plugin vulnerabilities are being exploited through outdated code
🔓 APIs and XML-RPC endpoints are being abused for DDoS (a type of cyber threat/attack in which hackers deny users from acessing services) and scraping

Real example: In late 2024, a hacked plugin injected malicious scripts into 50,000 WordPress sites — silently stealing form submissions. So, if you’re handling customer info, your site must be secure.

Quick WordPress Security Wins (Even Non-Techies Can Do)

Before we go deep, here are 5 easy things anyone can do today:

Change your admin username (never use “admin”)
Enable two-factor login (Google Authenticator, Authy, etc.)
Install a firewall plugin like Wordfence or iThemes Security
Turn off file editing inside the dashboard
Back up your site right now with UpdraftPlus or BlogVault

Small steps. Big protection.

Full Checklist: Securing WordPress the Right Way

1. Fortify the Login Area For Your WordPress Site

Use 2FA (two-factor authentication)
Rename wp-login.php using a plugin like WPS Hide Login
Limit login attempts to prevent brute force attacks

2. Keep Everything Updated

Turn on auto-updates for plugins, themes, and minor core releases
Test major updates in a staging environment first (WP Staging, LocalWP)
Avoid plugins/themes that haven’t been updated in 6+ months

3. Use Only Trusted Plugins and Themes

Check plugin reviews, update frequency, and active users
Avoid downloading from unofficial sources — nulled themes often contain malware
Scan the plugin code with Plugin Inspector or security plugins

4. Secure Your Hosting Environment

Your host plays a huge role in WordPress security.

Choose a host that offers:

Web Application Firewall (WAF)
Malware scanning and automatic patching
Support for disabling dangerous PHP functions like exec() and shell_exec()

Container-based WordPress hosting adds an extra layer of isolation.

5. Back Up Regularly (And Test It!)

Follow the 3-2-1 rule: 3 copies, 2 local, 1 offsite
Automate daily backups with tools like UpdraftPlus or JetBackup
Test restore points every 3–6 months

6. Install SSL & Enforce HTTPS

Use free SSL (Let’s Encrypt) or premium SSL
Force HTTPS using your .htaccess or plugin
Add HSTS headers to block insecure connections completely

7. Harden File Permissions & Sensitive Files

Set wp-config.php file permission to 600 or 640
Move it one level above public_html
Disable file editing inside WordPress:

phpCopyEditdefine('DISALLOW_FILE_EDIT', true);

8. Database Protection

Change the default table prefix from wp_ to something custom
Use a dedicated database user with limited permissions
Disable remote database access unless needed

9. Block or Limit XML-RPC

Unless you’re using Jetpack or remote publishing, disable it:

phpCopyEditadd_filter('xmlrpc_enabled', '__return_false');

Or block it entirely in .htaccess:

apacheCopyEdit<Files xmlrpc.php>
  Order Deny,Allow
  Deny from all
</Files>

10. DDoS Protection & Traffic Control

Use Cloudflare or Sucuri for traffic filtering and rate limiting
Monitor unusual spikes
Enable caching to reduce load (WP Rocket, LiteSpeed Cache)

11. File & Directory Hardening

Prevent PHP from running in /uploads/:

apacheCopyEdit<Directory "/wp-content/uploads">
  <FilesMatch "\.php$">
    Deny from all
  </FilesMatch>
</Directory>

Block public access to sensitive files like .env, .htaccess, and wp-config.php.

12. Monitor Activity in Real-Time

Use tools like:

WP Activity Log or Simple History for admin tracking
UptimeRobot or Better Uptime for downtime alerts
MalCare, Wordfence, or Patchstack for security scanning

Integrate alerts into Slack, Telegram, or email for real-time response.

What To Do If You Get Hacked

Don’t panic. Act fast:

Put the site in maintenance mode
Restore the latest clean backup
Scan your site and patch the entry point
Notify affected users if personal data was at risk
Analyze your logs and fix weak spots (e.g., outdated plugin)

Bonus: Use AI for Smarter Security

Some tools now use AI to detect patterns and threats:

MalCare & Jetpack Protect: AI-based threat detection
Use ChatGPT or custom scripts to review logs and flag anomalies
Monitor changes in /wp-content/ to catch hidden malware uploads

Final Takeaway: Security = Business Continuity

Securing your WordPress site isn’t just a tech chore — it’s business survival. Just follow the steps above to keep your site safe and secure. Also, always pick a good hosting provider so that they can handle the bigger problems.

In 2025, attackers are faster. But so are defenses — if you set them up right.
