The Ultimate WordPress Security Guide – Step by Step (2025)
By GwHosting
With over 800 million websites powered by WordPress, it’s no surprise that it’s a major target for cyberattacks. In 2025, securing your WordPress website is not optional—it’s essential.
Whether you’re a blogger, business owner, or developer, this step-by-step WordPress security guide will help you lock down your site, prevent breaches, and stay safe from evolving threats.
🛡️ Why Is WordPress Security So Important?
WordPress is an open-source platform, which makes it flexible—but also vulnerable when not configured properly. Common security risks include:
- Brute-force attacks
- Plugin/theme vulnerabilities
- Malware injections
- SQL injections
- Cross-site scripting (XSS)
At GwHosting, we believe proactive prevention is the best defense. So let’s dive into the essential steps for securing your WordPress site in 2025.
✅ Step 1: Keep Everything Updated
Always update your:
- WordPress core
- Themes
- Plugins
Outdated components are the #1 reason for WordPress hacks. Set updates to automatic or enable update alerts.
💡 Tip: Use only plugins/themes from trusted sources. Delete unused ones.
🔐 Step 2: Use Strong Login Credentials
- Use a unique username (avoid “admin”)
- Use a strong, random password with symbols and numbers
- Limit login attempts to prevent brute-force attacks
- Enable two-factor authentication (2FA)
Plugins like Limit Login Attempts Reloaded and WP 2FA make this easy.
🔒 Step 3: Install an SSL Certificate
SSL encrypts data between users and your website.
Look for https://
in your domain.
All GwHosting WordPress plans include free SSL certificates with automatic renewal.
🧱 Step 4: Install a Security Plugin
A good WordPress security plugin will:
- Monitor for malware and suspicious activity
- Block malicious IPs
- Harden key WordPress files
Recommended Plugins (2025):
- Wordfence
- iThemes Security
- Sucuri Security
🧑💻 Step 5: Set Proper File Permissions
Ensure the correct permissions:
wp-config.php
= 400 or 440- Folders = 755
- Files = 644
Misconfigured file permissions can allow attackers to inject code.
🗄️ Step 6: Regular Backups
Backups are your last line of defense. In case of an attack or crash, you’ll be able to restore your website quickly.
- Use plugins like UpdraftPlus or BlogVault
- Store backups in offsite locations (Dropbox, Google Drive, or cloud)
- Automate daily or weekly backups
GwHosting provides automated backups on all Managed WordPress Hosting plans.
🚫 Step 7: Disable XML-RPC
Unless you’re using apps that require it, disable XML-RPC to avoid brute-force and DDoS attacks.
Add this line to .htaccess
:
<Files xmlrpc.php>
Order Deny,Allow
Deny from all
</Files>
🛠️ Step 8: Harden WordPress Configuration
In your wp-config.php
:
- Disallow file editing:
define( 'DISALLOW_FILE_EDIT', true );
- Change database prefix from
wp_
to something unique - Move
wp-config.php
one directory above public_html (if your server supports it)
👥 Step 9: Manage User Roles Carefully
- Assign minimum required permissions to users
- Avoid giving Admin rights unnecessarily
- Regularly audit inactive users
Install “User Role Editor” plugin to customize permissions.
📈 Step 10: Monitor and Audit Activity
Keep an eye on:
- Login history
- File changes
- Suspicious actions
Use activity log plugins like WP Activity Log or Simple History to track everything.
