Outbound firewall applications come up many times in discussions about privacy as this is one way to monitor and prevent the apps you use from phoning home. Privacy Guides does not have any recommendation regarding outbound firewalls. I’d like to know your/everyone’s opinion about these kind of fir…

On Android you can use RethinkDNS: [image] GitHub - celzero/rethink-app: DNS over HTTPS / DNS over Tor / DNSCrypt client,... DNS over HTTPS / DNS over Tor / DNSCrypt client, WireGuard proxifier, firewall, and connection tracker for Android. I am actua…

It will help monitoring your internet traffic, point out any suspicious connections, unusual bandwidth consumption and if there are any non-consensual tracking/telemetry done or was introduced recently and to catch malware. Linux: [image] GitHub - evilsocket/opensnitch: OpenSnitch is…

I think it would be more useful to provide information on proper hardware firewalls instead. With an emphasis on ones with open source firmware support, as this provides an indirect privacy benefit and allows for more budget solutions. Not only will they provide much better firewall functionality b…

I am interested in physical firewalls as well, but I know nothing about them. Are there any brands or products that are recommendation-worthy?

Disclaimer: I co-develop an on-device “firewall” for Android. [image] anon29374801: Not only will they provide much better firewall functionality Debatable. The closer you’re to what you intend to block, the more surgical you can get. OS firewalls are better because they have more context (…

[image] ignoramous: Debatable. The closer you’re to what you intend to block, the more surgical you can get. I will concede on this point, you probably know more about firewalls then I ever will. [image] ignoramous: This is also a reason why in-browser plugins work better for content blo…

[image] anon29374801: wouldn’t a hardware firewall + browser extension be better then a software firewall + browser extension Yes, but more specifically: If browser is close to the only software you use, and you never install apps or services that potentially run in the background (other th…

Would everyone prefer a general “Firewalls” section with both software and hardware types? If we do implement this section, I would like additional discussion on specific recommendations (specifically for hardware-based firewalls) since this section would be very research-intensive.

I don’t think a single section would make much sense, since that would imply that you can freely choose between the two. (e.g. Choosing between cloud-based or self-hosted email, you don’t need both.) A con of a hardware firewall is that it will only protect you while on your home network (unless you…

Regarding macOS, also consider Little Snitch (Software Firewall for macOS). Although it’s a paid software and proprietary, I find it to be superior.
