/usr/share/secubox/plugins/catalog/*.json

Current modules (24 total):

• system-hub, vhost-manager, network-modes
• auth-guardian, client-guardian, bandwidth-manager

Automatic Discovery

The AppStore automatically discovers all modules with catalog entries:

$ secubox app list

Available Modules:
