Does CloudPanel Support ModSecurity? How to Enable It?

[Nemesis]

Does CloudPanel come with ModSecurity support out of the box? If not, how can I install and enable ModSecurity on a server running CloudPanel?

 

[Rootali]

CloudPanel does not include ModSecurity by default, as it’s designed to be lightweight and performance-focused. However, if you need Web Application Firewall (WAF) capabilities like ModSecurity, you can install and configure it manually.

What is ModSecurity?​

ModSecurity is an open-source WAF (Web Application Firewall) that protects your applications from common threats like:

• SQL injection
• Cross-site scripting (XSS)
• Path traversal
• And many more

Can You Use ModSecurity with CloudPanel?​

Yes — but it requires manual setup. CloudPanel uses Nginx (not Apache), so you’ll need to install ModSecurity as an Nginx module or use ModSecurity v3 (libmodsecurity).

Alternative: Use Cloudflare WAF​

If manual installation feels too complex, a simpler and CloudPanel-friendly alternative is to use Cloudflare’s WAF, which:

• Integrates easily with CloudPanel
• Offers DDoS protection and WAF rules
• Requires no server-side configuration

Summary:​

• ModSecurity is not built into CloudPanel
• You can install it manually (advanced users)
• Easier option: Use Cloudflare or Sucuri as external WAF solutions
