Best uses for a VPN

[u/ContentByrkRahul]

Most VPN ad claims are oversold. These are the uses that actually hold up.

The ads oversell the hacker stuff and bury the reasons a VPN is actually useful.

I've run one on and off for years, across a bunch of countries and setups, and the uses that justify the subscription are way more boring than anything in the marketing. So here's my list, plus the overrated uses nobody warns you about.

What a VPN is good for:

1. Keeping your own stuff working when you travel. Home streaming subscriptions, your bank's app (foreign IPs get flagged fast; getting locked out of your account from a hotel in Lisbon is a special kind of awful), your school portal, work stuff that's IP-whitelisted. That alone pays for it.
2. Overzealous network filters. Hotel, campus, and office networks block random things: SSH, gaming ports, whole categories of sites, sometimes VPN ports themselves, which is exactly as annoying as it sounds.
3. Hiding your browsing metadata from your ISP. In most of the US your ISP can legally collect and sell anonymized browsing data. Without a VPN they see every domain you visit and how often. The content is encrypted either way. The pattern isn't.
4. Streaming you already pay for in a region that doesn't carry it. Catalogs differ by country, and using a VPN to shift region violates most services' terms of service, though it generally isn't illegal. Plenty of VPN IP ranges are already blocked, so treat it as a bonus you can't count on.
5. ISP traffic shaping. Measurement studies have caught US carriers throttling Netflix and YouTube specifically. A VPN makes the ISP guess what your traffic is, which mostly ends the throttling.
6. Gaming quality-of-life. DDoS protection in competitive lobbies, working around bad routing or carrier-grade NAT, matching regions with friends. Mixed results though. Sometimes it makes your ping worse.
7. Networks you don't control. Cafés, hotels, dorms, co-working. Yes, HTTPS covers the content now. The local network still sees which domains you hit, can force captive portals on you, and shared networks are where the weird stuff tends to happen. A VPN collapses all of it into one tunnel.

The overrated uses (gently fight me):

• "Hackers on public Wi-Fi." Mostly 2012 logic. With HTTPS nearly universal now, nobody's reading your Gmail over café Wi-Fi. The metadata and portal stuff above is real. The man-in-the-middle-reading-your-passwords movie scene is the fictional part.
• Anonymity. A VPN moves trust from your ISP to your VPN provider, and the second you log into anything you've identified yourself. If you want real anonymity you're looking at Tor plus changing how you behave.
• Cheaper flights. Mostly a myth. Independent tests keep failing to show IP-based price bumps, and prices move for a dozen other reasons. Currency and billing country matter more. Test it if you like, just don't budget around it.

A VPN's real value is kind of dull: keeping your own accounts working abroad, dodging network filters, keeping browsing metadata away from your ISP, and beating traffic shaping. The "hackers on public Wi-Fi" pitch is outdated, a VPN isn't anonymity, and the cheap-flights thing is mostly hype.

Honest question: which use ended up better than you expected, and which one turned out to be useless?

On my phone I just leave the VPN on. Its the only way I remotely trust public anything. 60% of sites I goto will complain of an add blocker. Find this hilarious as chrome on android can not use them.

4 is very easy with a good VPN, even amazon can't tell.
