WHM Addon for Hosting Providers

The Defensia WHM addon adds a management panel to WHM's sidebar under Plugins > Defensia Server Security. From there, server administrators can:

• Install the Defensia agent on your server with one click
• View real-time agent status (version, uptime, connection status)
• Check if the server is protected and connected to the dashboard
• Quick links to the Defensia dashboard for full management
• Integrates with cPHulk brute force detection (automatic)

• cPanel/WHM 11.30+— Any modern WHM version
• Root access— Required for addon installation
• CentOS 7+ / AlmaLinux 8+ / CloudLinux 7+— Standard cPanel-supported OS
• curl— For downloading addon files
• Internet access— HTTPS outbound to defensia.cloud

• Verifies cPanel/WHM is installed on the server
• Downloads addon files from defensia.cloud/whm-addon/
• Installs the CGI script to /usr/local/cpanel/whostmgr/docroot/cgi/
• Copies static assets (CSS, JS, icon) to the WHM addon plugins directory
• Registers the addon in /var/cpanel/apps/defensia.conf
• Installs a one-command uninstaller at /usr/local/bin/defensia-whm-uninstall

• The addon uses Whostmgr::ACLS::hasroot() for authentication — only WHM root users can access it
• No cPanel user-level access — the addon is restricted to the WHM admin interface
• The addon does not modify any cPanel configuration files or system services
• All communication with the Defensia API uses HTTPS with TLS 1.2+
• The agent token is stored locally in /etc/defensia/config.json and never transmitted to third parties

To remove the WHM addon from the sidebar, run:

defensia-whm-uninstall

Or manually:

rm -f /var/cpanel/apps/defensia.conf
rm -f /usr/local/cpanel/whostmgr/docroot/cgi/addon_defensia.cgi
rm -rf /usr/local/cpanel/whostmgr/docroot/addon_plugins/defensia/
rm -f /usr/local/bin/defensia-whm-uninstall

If you manage multiple cPanel/WHM servers and want to deploy Defensia across your fleet, the WHM addon can be installed on every server via a simple script. Each server registers independently with your Defensia organization.

Multi-server deployment

# Deploy addon to multiple WHM servers
for host in server1.example.com server2.example.com; do
  ssh root@$host 'curl -fsSL https://defensia.cloud/whm-addon/install.sh | bash'
done
