Best firewall?

Hello guys,

My first macbook pro is coming! i've spent the last week learning about MACOS, how to operate it, the best apps etc.

From my findings, i realize that i won't be needing an antivirus, however i see 2 groups of people talking about firewalls:

- Those who say the default firewall is enough.

- Those who say you need a better one (with outbound protection too).

My highest concern is the following situation:

- I am at a local coffeeshop with my laptop, just browsing the mail...the web etc (nothing to serious like banking ofc), and then someone decides to launch a Man-In-The-Middle attack.

Would a good firewall block this? not that i'm visiting websites i shouldn't, but everyone deserves some privacy. Also, i wouldn't like someone getting my passwords.

So, i would like to hear what you experts think about firewalls for mac, and advise me a good one. thanks. Btw, i saw some comments on little snitch, but i see it hasn't been updated a long time so...

Just to finish my post, i would like to share a story:

Some years ago (maybe 2....3 years), a big friend of mine was in town and we decided to grab a coffee.

Since he brought his mac, i asked him "hey, lets check how secure is your mac?".

Sure, so i was with my android phone and launched an app called "Dsploit" and ran password sniffer.

In less than 2 minutes, i got all the passwords from all his e-mail accounts.

Turns out, the issue was with a mail client called "sparrow". Everytime the app checked for new mails, i was able to catch all the passwords (maybe something to do with ssl?i don't know).

My friend doesn't use sparrow now, never got problems again (as far as i know).

So, this is the kind of situation i want to avoid

P.S: sorry my bad english. Cheers

 

Hum, thanks a bunch for the replies. I once tried a VPN service. "mullvad", worked well on windows/linux. Didn't know that was able to hide from MIM attacks, that's great!
I'll have a look at little snitch . thanks guys
