I’ve never completely understood this, but I think the answer would probably be “no,” although I’m not sure. Usually when I leave the house I turn off wifi and just use mobile data (this is a habit from my pre-VPN days), although I guess I should probably just keep it on since using strange Wi-Fi with a VPN is ok (unless someone at Starbucks is using the evil twin router trick . . . ?). I was generally under the impression that mobile data is harder to interfere with than Wi-Fi, but I could well be wrong and my notions out of date. So, if need be, please set me straight. 🙂
The first step in security is to answer who you’re defending against. Someone stealing your phone? A cop with a STINGRAY device? All the security decisions you make are based on your initial threat model.
Generally, home internet, wifi, and cellular data are considered safe against passers-by (assuming your wifi password is strong). However, they are also assumed to be eavesdropped on by your ISP and government. Details of your internet traffic can then also be revealed by your ISP to other people during legal action, such as if you’re being investigated for piracy.
There are ways to further protect your internet traffic from being snooped on, even from your ISP and government, by using things like HTTPS, DNS over HTTPS, and of course, VPNs.
✔HTTPS 👍
✔VPNs 👍
I thought DNS over HTTPS (DoH!) was not recommended for some reason . . . My VPN provider claims to be using its own DNS servers.
Please note that the comment you’re replying to is leaving out a crucial piece of information: if your VPN provider is legally allowed to operate where you live, your government or law enforcement can get your data from them just as easily as they can get it from your ISP.
(Sorry for repeating myself but security is an important topic so I’d rather correct incomplete or misleading information in multiple comments than have someone miss the crucial part because they read only one sub-thread)
Definitely! If your VPN keeps logs, is in a surveillance-friendly jurisdiction, etc, then details of your internet traffic can be revealed by your VPN. I recommend Mullvad, paid with cash, for the most security. It can also help to pick VPN servers outside of the most egregious jurisdictions, like picking EU servers over US or HK servers.
Then I’ll repeat my comment from your earlier comment.
There’s no reason to make tracking easy for somebody just because it’s physically possible. Just because somebody can break into your house through your windows, doesn’t mean you shouldn’t lock your doors.
Data hygiene is important, when you know your retail ISP will definitely sell your net flow, it’s a strict net benefit to use a VPN to prevent them from making money off of you if nothing else
Sure, if you know that your ISP abuses your data, go ahead and do something. Though I would recommend changing ISPs before you give even more money to some other company who may or may not do the exact same thing to your data. I’m specifically not talking about TOR or some VPN that you host on your own. I’m talking about companies like NordVPN and Surfshark.
The analogy of locking your door doesn’t quite fit. Locking your door doesn’t cost you 10 dollars per month and doesn’t require you to hand your keys to the guy who sold you the lock.
You have more faith in your local ISP than I do. And I’m happy that you know for certain they are not selling your data. You must live in a very strong regulatory framework
Oh I most certainly don’t have much faith in my local ISP. But I have even less faith in some VPN startup funded by venture capitalists who may or may not be cutting corners on security to save a few bucks on their ends even if they’re not actively malicious. At least my local ISP has been around for decades and is closely monitored by both a government agency and independent customer protection groups.
And yes, I do live in a place with a very strong regulatory framework. Our ISPs are bound by the EU GDPR and our highest federal court has confirmed multiple times that even saving connection metadata without a case-specific court order is illegal. Sure, they could break those laws but a commercial VPN provider can do just the same with the difference that not as many people would notice.
I feel like one straw man in your arguments, is we keep mentioning mullvad in the comments, but you always compare it to the scummy VPNs like NordVPN.
Mullvad is also based in the EU, and the gdpr applies. They go out of their way to know as little about you as possible, if you pay with crypto or cash, they have no way to identify you as a person.
I checked and there is only a single comment that mentions Mullvad (other than yours that I’m replying to right now) that’s visible on my instance with no specific explanation why it’s better than other offers other than that you can pay with cash. If I’ve missed something, I promise you that it’s not in bad faith, it’s just that this distinction didn’t come through clearly.
I hadn’t heard about Mullvad before today and a quick look at their website made it look not very different from the fear-mongering you see with the others. Only after your comment I noticed the Why Mullvad VPN link at the very bottom that explains what they do differently. I’m still skeptical about some of the claims and especially of audits that they themselves requested but I’m happy to see that there are providers that seem to be more trustworthy than the ones that are constantly shoved down our throats and I’m definitely happy to have learned something new.
May I suggest that you write a top level comment that explains in detail why Mullvad is better than other services so OP (and others who stumble over this thread) has an easier time finding it?
Edit: minor typos and grammar
DoH is meant to hide your internet activity from your ISP/cell-provider since DNS is otherwise unencrypted. If you trust your VPN, then you can trust unencrypted DNS.
