Cyberattacks on websites are becoming more sophisticated every year, and WordPress remains one of the most targeted platforms because of its popularity. While WordPress itself is a secure content management system, outdated plugins, weak passwords, and poor hosting practices often create vulnerabilities that attackers can exploit.
The good news is that you don’t need to be a cybersecurity expert to improve your website’s security. By following a set of proven best practices, you can significantly reduce the risk of malware infections, brute-force attacks, and unauthorized access.
In this guide, we’ll explain how to protect your WordPress website from hackers and keep your business running securely.
Why Are WordPress Websites Targeted?
WordPress powers more than 40% of websites on the internet, making it an attractive target for automated attacks. Most hackers aren’t interested in a specific website—they use bots to scan thousands of sites looking for common weaknesses.
Common attack methods include:
- Weak administrator passwords
- Outdated WordPress core
- Vulnerable plugins
- Outdated themes
- Malware uploads
- Brute-force login attempts
- SQL Injection
- Cross-Site Scripting (XSS)
- File inclusion vulnerabilities
Many successful attacks are preventable with regular maintenance and basic security practices.
1. Keep WordPress Updated
One of the simplest ways to improve security is to keep your installation updated.
Always update:
- WordPress Core
- Plugins
- Themes
- PHP Version
Updates frequently include security patches that fix known vulnerabilities before attackers can exploit them.
Tip: Remove unused plugins and themes instead of simply deactivating them.
2. Use Strong Passwords and Multi-Factor Authentication (MFA)
Weak passwords remain one of the leading causes of compromised WordPress websites.
Choose passwords that are:
- At least 16 characters long
- Unique for each account
- Stored in a password manager
- Never reused across websites
Enable Multi-Factor Authentication (MFA) to add an extra layer of protection. Even if a password is stolen, MFA can prevent unauthorized access.
3. Limit Login Attempts
Hackers often use automated bots to try thousands of password combinations.
Limit failed login attempts to reduce the effectiveness of brute-force attacks.
Recommended settings:
- Maximum login attempts: 3–5
- Temporary lockout after failed attempts
- Progressive lockout for repeated failures
Many security plugins provide this feature out of the box.
4. Install a Web Application Firewall (WAF)
A Web Application Firewall filters malicious traffic before it reaches your website.
A WAF can help block:
- SQL Injection
- Cross-Site Scripting (XSS)
- Known exploit attempts
- Malicious bots
- DDoS traffic
Cloud-based firewalls also improve website performance by filtering unwanted traffic closer to the visitor.
5. Use Reputable Security Plugins
Security plugins can automate many routine protection tasks, including malware scanning, login protection, file monitoring, and firewall rules.
When choosing a plugin, look for features such as:
- Malware scanning
- Firewall protection
- Login security
- File integrity monitoring
- Security notifications
Avoid installing multiple plugins that perform the same security functions, as they can conflict with one another.
6. Choose Secure Hosting
Your hosting provider plays a major role in website security.
Look for hosting that offers:
- Automatic backups
- Malware scanning
- Server firewall
- SSL certificates
- PHP version management
- Daily monitoring
- Isolated hosting environments
- Regular server updates
Cheap hosting often lacks proactive security measures.
7. Use SSL (HTTPS)
An SSL certificate encrypts communication between visitors and your website.
Benefits include:
- Secure login credentials
- Better trust
- Browser security indicators
- Improved search engine rankings
- Protection against data interception
Ensure every page redirects to HTTPS.
8. Backup Your Website Regularly
Backups are your safety net if something goes wrong.
Follow the 3-2-1 backup strategy:
- Three copies of your data
- Two different storage locations
- One off-site backup
Test your backups periodically to confirm they can be restored successfully.
9. Remove Unused Plugins and Themes
Inactive components can still contain vulnerabilities.
Regularly:
- Delete unused plugins
- Delete unused themes
- Remove abandoned software
- Review installed extensions
Keep only what your website actively uses.
10. Change the Default Admin Username
Avoid using “admin” as the administrator username.
Instead:
- Create a unique administrator account.
- Transfer administrator privileges.
- Remove or demote the default account if appropriate.
This makes automated attacks less effective.
11. Disable File Editing from the Dashboard
By default, WordPress allows administrators to edit theme and plugin files from the dashboard.
If an attacker gains admin access, this feature can be abused to inject malicious code.
Disable file editing by adding the appropriate configuration directive to your WordPress configuration.
12. Monitor File Changes
Unexpected file modifications may indicate a compromise.
File monitoring helps detect:
- Backdoors
- Injected scripts
- Unauthorized changes
- Malware uploads
Investigate unexpected changes promptly.
13. Scan for Malware
Regular malware scans help identify infections before they spread.
A comprehensive scan should check for:
- Malicious PHP files
- Hidden backdoors
- Spam injections
- Redirect scripts
- Suspicious code patterns
Combine automated scans with periodic manual reviews for better coverage.
14. Secure File Permissions
Correct file permissions reduce the risk of unauthorized modifications.
As a general guideline:
- Files should be readable by the web server but not writable by everyone.
- Directories should allow necessary access without granting excessive permissions.
- Avoid setting permissions to
777, which grants full access to all users.
If you’re unsure, consult your hosting provider or system administrator before making changes.
15. Disable XML-RPC if Not Needed
XML-RPC is rarely required for many modern WordPress sites.
If unused, disabling it can reduce exposure to:
- Brute-force attacks
- Pingback abuse
- Amplification attacks
Only disable it after confirming that your workflows and plugins do not depend on it.
Signs Your Website May Already Be Hacked
Watch for warning signs such as:
- Unexpected redirects
- Google security warnings
- New administrator accounts
- Spam pages appearing in search results
- Unusual resource usage
- Unknown files or folders
- Website slowdown
- Antivirus warnings
- Emails being sent without your knowledge
If you notice any of these symptoms, investigate immediately.

Frequently Asked Questions
Is WordPress secure?
Yes. WordPress core is actively maintained and regularly updated. Most security incidents result from outdated plugins, themes, weak passwords, or poor maintenance rather than the core software itself.
Can free plugins make my website vulnerable?
They can if they are poorly maintained or abandoned. Choose plugins from reputable developers, keep them updated, and remove those you no longer use.
Do I need a security plugin if my hosting includes security features?
Hosting-level protections are valuable, but they don’t replace website-level security. Many sites benefit from a combination of secure hosting, strong authentication, regular updates, and targeted monitoring.
How often should I back up my website?
For frequently updated sites, daily backups are a good baseline. High-traffic or eCommerce websites may require more frequent backups.
Can a hacked website affect SEO?
Yes. Malware, spam content, redirects, or browser security warnings can lead to ranking drops and loss of visitor trust.
Conclusion
Protecting your WordPress website doesn’t require a single “magic” solution. Instead, it’s about combining secure hosting, timely updates, strong authentication, regular backups, and ongoing monitoring into a layered security strategy.
By following the practices outlined in this guide, you can significantly reduce your risk of compromise and improve the long-term reliability of your website. Security is an ongoing process, so review your setup regularly and address potential vulnerabilities before they become problems.
If your website has already been compromised, consider using professional cybersecurity services to identify vulnerabilities, remove malware, and strengthen your website against future attacks.
