A safe access to my home infra/lab.

From my experience, the latency can be neglected in comparison of the latency of the connection of a mobile.

When the VPN has connexion issues, all the apps on my phone are waiting. Some reach timeout. But they recover all at once, without DNS issues, when the VPN comes back up.

When I move from network to network, from private wifi to public wifi, from country to country, … I am know I can try hotspots without checking if it’s from a malevolent entity (private hacker, stupide enterprises (who log for whatever reason that I go on website they don’tlike (pro-abortion, gaming, …), or anything else). If the VPN is up, I can. If it is down, I can’t but there’s no risk for me, just momentary annoyance.

Yar har fiddle dee dee…

Other comment have gone way more in-depth, but there’s also a difference between using commercial VPNs and ones you set up yourself. I have a few private VPNs set up on servers I physically own in different countries and that offers different protections than just using NordVPN.

Pros:

• Websites can’t see your real IP and thus can’t figure out your real location that easily
  • You might also be able to blend in with other users who use the same VPN server
• Your ISP can’t see what you’re websites you’re connecting to
• Your Network operator (e.g. a coffee shop offering public wifi) and you’re ISP can’t see your unencrypted connections (e.g. HTTP, Telnet)
• You can bypass regional censorship or other forms of content unavailability

Cons:

• Your VPN provider can see everything you’re connecting to (but not the content if you use HTTPS, which thankfully has become very common), so you need to be able to trust them
• A good and trustworthy VPN usually costs money
• Slightly slower connection and higher latency

Things to look out for when choosing a VPN provider:

• No-log policy
• Regular security audits
• Open source client applications
• Private/anonymous payment options (crypto currency)
  • Monero is the best option if you want to stay fully anonymous
• Minimal information required for signing up, ideally none (some providers don’t even require an email address, they just give you a random generated Account ID)

Most people in the US use it to avoid getting letter from their ISP from downloading illegal content.

Some people use to access other country content.

Some people use it to avoid ISP snooping their browsing habits

A few ways I’ve used it.

Odd, a site seems to be non-functional. (Enable VPN). Site begins to work. Oh, my ISP was fucking with me.

A site is stuttering. (Enable VPN). Magically works. Oh, my ISP was fucking with me.

The most annoying, my family’s Internet over the holidays was blocking my laptop from updating Ubuntu, enabled VPN, udpate went just fine.

In general, it stops ISPs from dictating if they approve or disapprove of your behavior. Hide what you’re doing and all traffic is just anonymous bits and bobs.

As it fucking should be by law… but in the US the conservative party continually repeals the law that enforces non-interference. So for now, we need VPNs.

i enjoy not getting threatening letters from my ISP about downloading shit.

You should consider your threat model first before using something without being unsure of the benefits.

I’m not smart enough to explain the privacy benefits, but what I can say is that a vpn is so useful for getting access to region-locked websites. People usually mention that you’ll get access to exclusive Netflix content, but if you’re the sort to use a vpn at all, you’re probably not the sort to use Netflix anyway. With a vpn, I can use Tubi despite living outside the US, and novel-translation sites that refuse traffic from my country don’t even give those ‘verify you’re a human’ prompts.

Also, I can switch locations to a place with better upload/download speeds, so things that would before take at least 5 minutes get done in seconds.

I’ve never felt the need to use a VPN at home. I’m not really trying to hide from my own ISP, nor obfuscate where my connections come from.

I do host my own VPN from my home network though. This allows me to access my self-hosted services without exposing them directly to the internet, as well as keeps my mobile devices behind my pihole dns servers so they always receive dns adblocking and access to private dns records (self-hosted stuff). This also keeps mobile traffic a bit more secure from snooping, particularly on public/corporate wifi networks.

I find this Tom Scott video (YouTube) to be pretty good at explaining why you would want a VPN and why most marketing arguments are BS.

Eli5 VPN: https://dnsleaktest.com/ Visit this site unsecured and it will display your general geographic location (county/region). Connect to your VPN and try again incognito and under most circumstances it will display the VPN location instead.

Example scenario: you are in Canada and connect to Netflix and are incredibly disappointed with the Canadian selection. You connect toa VPN from New York a few miles away and you get access to the full United States catalogue. (Netflix is fighting this)

Example 2: you setup your smart vacuum on your home network and being concerned about security, you disabled access outside your home. You can connect to a personal VPN you configure to “spoof” being inside the house while on vacation to modify your vacuum settings.

Vpns are also commonly used as “public transit” for users to obfuscate their identity.

Benefit: When you make a request against a website, they often put trackers on you including your operating system, browser application, and store data like your geographic location. Advertisers are tracking your history, sites are using cookies to charge more with dynamic pricing when you revisit, data brokers are selling that data. There have been use cased where whistle blowers are identified off that purchased data from known journalist meetings. There’s a lot of reasons to have a VPN, but never use a free one. Adding an extra jump to your VPN location is definitely adding latency, if you don’t need one, it’s just extra weight.

It hides details on your traffic from your ISP, that’s about it.

Your ISP can really only see the domain names you visit, as HTTPS encrypts the other info like the path and actual content.

If you don’t use VPN all your traffic will flow through ISP. That doesn’t mean ISP can see your passwords or anything. They can only see which website you’re connecting to given that you are using unencrypted DNS if you are using encrypted DNS with TLS Hello they can only see IP. The claims that VPN protects you from hackers in public WiFi is dead since all websites switched to HTTPS and HSTS.

By using VPN all of these details now won’t be visible to your ISP but they will be visible to VPN provider.

If you live in a place where LEA can’t kick down your door and arrest you for visiting website it deems illegal then using VPN doesn’t give you anything.

Of course even a lot of first world country have strict laws against piracy in that case VPN is good but if you aren’t pirating and live in a free country I’d suggest don’t bother with VPN unless you have other reasons.Another reason could be to access geo restricted content on Netflix and stuff

Another thing to keep in mind, if you are committing/suspected of any crime then LEA will definitely go through your search history, they can get this through your device if you’ve cleaned that up but use google account then they can ask google, or go to ISP and ask this, obviously if you’re in this category then there are better solutions like Tor I2P

There are other extreme examples where a cheap ad friendly VPN with no registration comes in handy. If you want to create a zero knowledge email. Most email provider will block you if you are trying to create account with ProtonVPN or from Tor, but if your route your traffic through Tor and then to an ad friendly VPN they mostly allow it cuz they think you’re a dumb dumb. Note - it is generally not recommended to use VPN over Tor.

Nice try FBI
