WordPress powers over 43% of all websites on the internet. That popularity makes it a massive target for hackers, scammers, and automated bots looking for vulnerabilities to exploit.

Every day, thousands of WordPress sites get hacked. The consequences can be devastating:

The good news? Most WordPress hacks are completely preventable. With the right security measures in place, you can protect your site from 99% of attacks.

This comprehensive guide will show you exactly how to secure your WordPress site, recognize vulnerabilities, and respond if the worst happens.

Understanding WordPress Security Threats

Before we dive into solutions, let’s understand what you’re defending against.

Common Attack Vectors

1. Brute Force Attacks

Automated bots try thousands of username/password combinations to gain access to your admin panel.

2. Malware Injection

Malicious code inserted into your site to:

3. SQL Injection

Attackers exploit poorly coded plugins or themes to:

4. Cross-Site Scripting (XSS)

Malicious scripts injected through:

5. Outdated Software Vulnerabilities

Hackers scan for:

6. Phishing Attacks

Attackers target you or your team:

7. DDoS Attacks (Distributed Denial of Service)

Overwhelming your server with traffic to:

8. File Upload Exploits

Malicious files uploaded through:

Why WordPress Sites Get Hacked

Most WordPress hacks succeed because of:

The theme here? Most hacks are preventable with basic security hygiene.

The Essential WordPress Security Checklist

Let’s walk through the critical security measures every WordPress site needs.

1. Use Strong Passwords and Authentication

This is Security 101, yet it’s still the most common vulnerability.

Password Requirements

Every account with access to your WordPress site should use:

Bad password examples:

Good password examples:

Use a Password Manager

Don’t try to remember complex passwords. Use a password manager:

These tools generate and securely store unique passwords for every site.

Never Use “admin” as Your Username

The default “admin” username is the first thing hackers try. Instead:

If you already have an “admin” user:

  1. Create a new administrator account with a unique username
  2. Log out and log back in with the new account
  3. Delete the old “admin” account

Implement Two-Factor Authentication (2FA)

2FA adds a second layer of security beyond passwords. Even if someone gets your password, they can’t log in without the second factor.

How it works:

  1. Enter username and password
  2. Enter a code from your phone (via app or SMS)
  3. Access granted

Recommended 2FA plugins:

Best practice: Use an authenticator app (Google Authenticator, Authy) rather than SMS codes, which can be intercepted.

Limit Login Attempts

By default, WordPress allows unlimited login attempts. That makes brute force attacks easy.

Solution: Install a plugin to limit login attempts:

Recommended settings:

Change Your Login URL

The default WordPress login is yoursite.com/wp-admin. Hackers know this and target it relentlessly.

Solution: Change your login URL to something obscure:

Plugins to change login URL:

Warning: Document your new login URL! If you forget it, you’ll need to access your database to fix it.

2. Keep Everything Updated

Outdated software is one of the top causes of WordPress hacks. Every update includes security patches.

WordPress Core Updates

Update WordPress as soon as new versions are released:

How to update:

  1. Dashboard → Updates
  2. Click “Update Now”
  3. WordPress will back up and update automatically

Before major updates:

Plugin Updates

Plugins are a common attack vector because:

Best practices:

Warning signs a plugin might be insecure:

Theme Updates

Themes can also have vulnerabilities:

Best practices:

Child themes: If you’ve customized your theme, use a child theme so updates to the parent theme don’t overwrite your changes.

PHP Version

Your server’s PHP version matters for security and performance:

Check your PHP version: Dashboard → Site Health → Info → Server

Update PHP through your hosting control panel or ask your host to update it.

3. Choose Secure Hosting

Your hosting provider is your first line of defense.

What Secure Hosting Includes

Look for hosts that offer:

Avoid Budget Shared Hosting

$3/month hosting is cheap for a reason:

For small business sites:

For larger sites:

Avoid: GoDaddy, Bluehost, HostGator (cheap but poor security and support)

Enable SSL/HTTPS

An SSL certificate encrypts data between your site and visitors:

Most hosts offer free SSL certificates. Enable it and force all traffic to HTTPS:

  1. Install SSL certificate (usually one-click in hosting control panel)
  2. Install a plugin like Really Simple SSL to force HTTPS
  3. Update any hardcoded HTTP links in your database

4. Install a Security Plugin

A comprehensive security plugin provides multiple layers of protection.

Top WordPress Security Plugins

1. Wordfence Security (Free + Premium)

Most popular security plugin with:

Premium version ($119/year):

2. Sucuri Security (Free + Premium)

Premium version ($200-500/year):

3. iThemes Security (Free + Premium)

Premium version ($80-200/year):

4. All In One WP Security & Firewall (Free)

Beginner-friendly with:

Our recommendation: For most sites, the free version of Wordfence provides excellent protection. Upgrade to premium if you’re handling sensitive data or in a high-risk industry.

Security Plugin Setup

After installing a security plugin:

  1. Run an initial scan to identify vulnerabilities
  2. Enable firewall protection
  3. Set up login security (limit attempts, 2FA)
  4. Enable malware scanning (daily or weekly)
  5. Configure email alerts for important security events
  6. Review and implement recommended hardening measures

Don’t just install and forget—configure it properly.

5. Regular Backups

Backups don’t prevent hacks, but they ensure you can recover quickly.

Backup Best Practices

What to back up:

How often:

Where to store backups:

Backup Plugins

1. UpdraftPlus (Free + Premium)

Most popular backup plugin:

Premium version ($70/year):

2. BackupBuddy (Premium - $80/year)

3. VaultPress (Jetpack Backup) (Premium - $10-50/month)

By Automattic (WordPress creators):

4. BlogVault (Premium - $89/year)

Manual Backup Options

cPanel backups:

Database export:

File transfer:

Best practice: Use an automated plugin for regular backups, plus manual backups before major changes.

6. Harden WordPress Configuration

Security hardening means making WordPress more difficult to attack.

Secure wp-config.php

Your wp-config.php file contains sensitive database information. Protect it:

1. Move it outside the web root (advanced):

2. Set proper file permissions:

chmod 440 wp-config.php

3. Disable file editing from the WordPress admin:

Add this to wp-config.php:

define('DISALLOW_FILE_EDIT', true);

This prevents theme/plugin editing from the dashboard, blocking a common attack method.

4. Change database table prefix:

Default prefix is wp_—change it to something random during installation, or use a plugin like iThemes Security to change it later.

5. Add security keys:

WordPress uses security keys to encrypt information. Generate unique keys at https://api.wordpress.org/secret-key/1.1/salt/ and replace the defaults in wp-config.php.

Protect .htaccess File

Add these security rules to your .htaccess file:

Block access to wp-config.php:

<files wp-config.php>
order allow,deny
deny from all
</files>

Protect .htaccess itself:

<files .htaccess>
order allow,deny
deny from all
</files>

Disable directory browsing:

Options -Indexes

Protect wp-includes:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^wp-admin/includes/ - [F,L]
RewriteRule !^wp-includes/ - [S=3]
RewriteRule ^wp-includes/[^/]+\.php$ - [F,L]
RewriteRule ^wp-includes/js/tinymce/langs/.+\.php - [F,L]
RewriteRule ^wp-includes/theme-compat/ - [F,L]
</IfModule>

Note: Many security plugins add these automatically.

Disable XML-RPC

XML-RPC is often exploited for brute force attacks. Unless you need it for specific integrations, disable it:

Add to .htaccess:

<Files xmlrpc.php>
order deny,allow
deny from all
</Files>

Or use a security plugin to disable it.

Remove WordPress Version Number

Don’t advertise your WordPress version to attackers:

Add to your theme’s functions.php:

remove_action('wp_head', 'wp_generator');

Disable File Editing

We mentioned this earlier—add to wp-config.php:

define('DISALLOW_FILE_EDIT', true);

Set Proper File Permissions

Correct file permissions prevent unauthorized modifications:

Use FTP or SSH to set permissions.

7. Database Security

Your WordPress database contains everything: content, users, settings.

Use Strong Database Credentials

Change Database Table Prefix

Default is wp_—use something random like wp_k8m2_ to make SQL injection harder.

Change during installation or use a plugin like iThemes Security.

Regular Database Optimization

Over time, databases accumulate spam, revisions, and overhead:

Optimize regularly:

Plugins:

Database Backups

We covered this earlier, but worth repeating: back up your database separately and regularly.

8. Secure User Accounts and Roles

Compromised user accounts are common attack vectors.

User Role Best Practices

WordPress has different user roles with different permissions:

Rules:

Remove Default “admin” User

We covered this earlier—never keep the default “admin” username.

Monitor User Activity

Use a plugin to log user actions:

WP Security Audit Log (free):

Helps you detect suspicious activity.

Require Strong Passwords

Force users to create strong passwords:

iThemes Security or Force Strong Passwords plugin can:

9. Secure File Uploads

File upload vulnerabilities let attackers inject malicious code.

Restrict File Types

Only allow necessary file types:

Add to wp-config.php:

define('ALLOW_UNFILTERED_UPLOADS', false);

Use a plugin to restrict file types further (e.g., block .php, .exe, .sh files).

Scan Uploads for Malware

Security plugins like Wordfence and Sucuri scan uploaded files for malware.

Limit Upload Permissions

Only trusted users (Administrators, Editors) should upload files.

10. Implement a Web Application Firewall (WAF)

A WAF sits between your site and the internet, filtering malicious traffic before it reaches your server.

Cloud-Based WAF

Cloudflare (Free + Paid):

Sucuri Firewall ($200-500/year):

Wordfence Premium ($119/year):

Plugin-Based Firewall

Free security plugins include basic firewalls:

Limitation: Plugin firewalls run after WordPress loads, so they can’t block all attack types. Cloud-based WAFs are more effective.

11. Monitor and Respond to Threats

Security isn’t “set and forget”—you need ongoing monitoring.

What to Monitor

1. Failed login attempts:

2. File changes:

3. Malware scans:

4. Uptime monitoring:

5. Blacklist status:

6. User activity:

Monitoring Tools

Wordfence:

Uptime monitors:

Google Search Console:

Sucuri SiteCheck (free):

Set Up Email Alerts

Configure your security plugin to email you when:

Don’t ignore these alerts.

12. Avoid Risky Plugins and Themes

Not all plugins and themes are created equal.

Red Flags

Avoid plugins/themes that:

Where to Get Safe Plugins/Themes

Trusted sources:

Research before installing:

Limit Plugin Count

More plugins = more potential vulnerabilities:

What to Do If You Get Hacked

Despite your best efforts, hacks can still happen. Here’s your response plan.

Step 1: Stay Calm and Assess

Don’t panic. Figure out what happened:

Step 2: Take the Site Offline

Put up a maintenance page to:

Use a plugin like WP Maintenance Mode or contact your host to temporarily disable your site.

Step 3: Change All Passwords

Immediately change:

Use strong, unique passwords.

Step 4: Scan for Malware

Run a thorough malware scan:

Identify infected files.

Step 5: Restore from Clean Backup

If you have a clean backup from before the hack:

Important: Make sure the backup is from BEFORE the hack occurred.

Step 6: Manual Cleanup (If No Clean Backup)

If you don’t have a clean backup:

  1. Delete malicious files identified in scans
  2. Replace WordPress core files with fresh downloads
  3. Reinstall plugins (delete old versions, install fresh)
  4. Check database for malicious code (especially in posts, comments, options table)
  5. Review .htaccess for suspicious code
  6. Check wp-config.php for unauthorized changes

This is tedious and error-prone. Consider hiring a professional.

Step 7: Update Everything

Close any vulnerabilities that allowed the hack.

Step 8: Re-harden Security

Step 9: Request Malware Removal from Google

If Google blacklisted your site:

  1. Log into Google Search Console
  2. Navigate to Security & Manual Actions
  3. Request a review after cleaning up
  4. Google will re-scan and remove the warning if clean

Step 10: Notify Affected Parties

If customer data was compromised:

When to Hire a Professional
