Security Levels

I’ve had my firewall & proactive defense set to safe mode since I installed Comodo Firewall, can I leave it set to safe mode or would be it be safer to change the level? I done abit of googling a month or so ago and afew people said it was safe to leave both in safe mode, is there any truth in that? I’m on a stand alone pc, no router or network sharing… my systems names billy no mates and it would like to remain that way.

You can leave them in safe mode.

That’s how I run them.
