Out of the box settings

Are the out of the box settings fine or does anything need to be changed to achieve maximum security?

I believe they are fine, according to “general info” (e.g. from the website). You may want to increase the Firewall alert frequency level, then go to Firewall tab / Advanced tab / Alert Settings tab, and you can raise it from “Low” to something else. You can also change the Defense+ settings, if you go to Defense+ tab / Advanced tab / General Settings tab. But generally you really don’t have to change anything here!!
