Introduction
Security is a top priority for any website owner. Joomla, being a powerful and flexible CMS, is no exception. While Joomla has a solid core with strong built-in security features, maintaining a secure Joomla site also depends on proper configuration, secure hosting, regular updates, and the use of trusted security extensions.
This guide is your comprehensive resource to securing your Joomla website in 2025. Whether you’re a site administrator, developer, or business owner, we’ll cover everything you need — from best practices to the top Joomla security extensions — to keep your site protected from vulnerabilities, attacks, and data breaches.
Why Joomla Security Matters
Joomla powers thousands of websites worldwide, making it a target for cyberattacks such as:
- SQL injection
- Cross-site scripting (XSS)
- Brute-force login attempts
- Malware injection
- Spam and bot traffic
A security breach can result in defaced content, stolen user data, blacklisted domains, or even complete site takeovers. Following a structured Joomla security approach helps prevent such disasters and builds trust with your audience.

Joomla Security Best Practices
Beyond using security extensions, follow these best practices to minimize risks:
Keep Joomla Core & Extensions Updated
Always install the latest versions of:
- Joomla CMS
- Extensions
- Templates
Patches often include fixes for known vulnerabilities.
Use Strong Administrator Passwords
- Use complex, unique passwords
- Enable 2FA via Google Authenticator or YubiKey
- Limit admin account access
Bonus Tip: Rename the default administrator login URL using extensions like AdminExile.
Secure File & Folder Permissions
Set recommended file permissions:
- Files: 644
- Folders: 755
- Configuration file (configuration.php): 444
Avoid 777 permissions at all costs.
Backup Regularly
Use tools like Akeeba Backup to automate regular backups. Store them off-site (e.g., Google Drive or Dropbox) and test them monthly.
Disable Unused Extensions & Services
- Remove outdated or unused extensions
- Turn off unnecessary modules or plugins
- Disable FTP layer in Global Configuration unless needed
Use HTTPS Everywhere
- Install an SSL certificate (Let’s Encrypt offers free ones)
- Force HTTPS via Joomla’s Global Configuration > Server tab
- Update .htaccess file for redirection
Set Up a Web Application Firewall (WAF)
Use a WAF either through hosting or services like Cloudflare or Sucuri to block suspicious traffic before it hits your Joomla site.
Monitor Site Logs
Regularly check server logs, Joomla logs, and your security extension logs. Look out for:
- Multiple failed login attempts
- Unexpected file changes
- Unusual traffic spikes
Securing Joomla Login and Admin Panel
- Change the default admin path using plugins
- Limit login attempts using extensions
- Create a separate user role with limited access
- Use IP whitelisting to restrict access to backend
Hosting and Server-Level Security Tips
- Choose a Joomla-optimized hosting provider
- Enable server-level firewalls
- Disable directory listing
- Use PHP 8.2 or higher for better performance and security
- Restrict database access to localhost only
How Joomla Itself Helps You Stay Secure
Joomla 5.1 (2025) brings core improvements like:
- Enhanced session security

- Automatic security updates (if enabled)
- Modern PHP support (PHP 8.2+)
- Better logging and debugging tools
The Joomla Security Strike Team (JSST) actively maintains a vulnerability list and responds quickly to threats.
