Is your feature request related to a problem? Please describe.
Crowdsourced Network Security is the latest in intelligent and dynamic firewall management. Inspired by Fail2ban, it uses a "Crowd-Sourced Cyber Threat Intelligence" model that combines behavior analysis and IP reputation to detect and mitigate various cyber threats.

Describe the solution you'd like
Would like to see a check to see if crowdsec and bouncers are installed and active.

Required changes
Simple check to see if Crowdsec is installed and bouncers are configured and active.

Additional context
This will allow network administrators and people new to network security explore the option to hardening the system as much as they can with crowdsourced technology.
