Is the stealth mode of the macOS firewall good enough ?

Hello everyone,

I would like get your input on whether or not the stealth mode of the macOS firewall is enough to stay totally invisible on public networks (airports, cafés etc) but also at home against potential network-savvy malware that other, less "locked down", devices could catch.

In order words are there counter measures for hackers and malware/worm/virus etc coders to still detect me while on stealth mode with my Mac.

Thanks a lot !
