Can someone explain to me the advantages of using a VPN?

I've been using one but I'm not sure what benefits I'm getting from it. I feel like the only thing happening is I'm adding a little bit of latency to all my requests for no reason.

  • 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.

  • 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.

  • 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.

  • i don’t want ppl to know my business, is what i tell most ppl to keep it short and sweet, haha

  • 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.

  • You can use your file server, your git server, your plex server, etc. when you're not at home.

    Oh, you mean the advantages of using somebody ELSE'S vpn?? They get money.
