In linuxes has no open ports by default, so firewall is unnecessary for desktop user.
Unless you're on a shared (semi) public network, and unless you've installed non-default software that does open ports.... :wink:

Is Open Snitch sufficiently mature for prime-time yet?

OK I see the confusion - pfsense is not a firewall that one installs on a linux mint computer. Or at least one should not. Alhough I see where there are instructions to do so using a VM which seems like a really bad idea. It looks to me that pfsense is a firewall on a separate hardware platform (you can buy it preloaded on their hardware or load it on your own) which can add security in depth. In effect it looks like a router firewall or even a router behind a router firewall I suppose.

So sure, OK if you want to spend the $$$
Yes, that was the confusion. You are supposed to use pfsense in place of your hardware router.

The fact is security is effective when a multi layered approach is taken.
The problem is, that using 2 personal firewall in the same system can introduce stability issues and in case, that one of the them has a security flaw, this can affect also the other firewall. Every firewall runs with elevated rights and they use necessarily the same kernel. If one of them has a leak, the system has this leak. (If there is no leak, the second firewall can in best case do nothing better than the first.)

Quite obviously configuring 2 firewalls is more complicated and bears much more potential for mistakes than only one. Not only can this disturb the needed network connection; possibly the users does in consequence a configuration mistake, which can destroy the purpose of the firewall completely.

A router firewall is quiet a different thing, because it runs on a different physical system. Leaks in one place cannot affect the other one. If a hardware firewall (router) i no longer safe, because abandoned, you need to replace it. A second software firewall is the wrong and also dangerous measurement..
Pfsense is supposed to work as a hardware firewall and it runs on a different physical system.
