Do you actually need a VPN?
VPNs are advertised as a cure-all for online safety. They're not — but they are genuinely useful for a few specific jobs. Here's the honest version: what a VPN really does, what it definitely doesn't, and when it's actually worth having.

What a VPN actually does
A VPN sends your internet traffic through an encrypted tunnel to a server run by the VPN company, which then forwards it to the wider internet. The practical results — the genuinely useful ones — are:
- hides your IP address from the websites you visit
- stops your internet provider — or the operator of public Wi-Fi — from seeing which sites you visit
- lets you appear to be in another country, for travel or streaming
That makes it a real tool for public Wi-Fi, for keeping your internet provider out of your browsing, and for travel and streaming. Those are good reasons to have one.
What a VPN doesn't do (despite the ads)
This is where the marketing oversells. A VPN does not:
- make you anonymous — you're still logged into your accounts, and the VPN company can see your connection metadata (which sites you connect to), even though HTTPS keeps the page contents themselves encrypted (which is exactly why a no-logs policy and independent audits matter)
- replace antivirus or a password manager
- stop cookies, trackers or fingerprinting once you're on a site
- protect you if you hand your password to a phishing page
If a VPN ad promises "total anonymity" or "complete protection," treat it as a red flag — the honest providers don't make those claims.
So — do you need one?
Yes, if: you regularly use public Wi-Fi, you don't want your internet provider logging your browsing, you travel and need to reach services from home, or you want to stream content from another country. Not really, if: you only browse trusted sites on your own home network and aren't trying to hide your traffic from your provider — modern HTTPS already encrypts the sensitive part.
And if you do get one, the rule is simple: pick a provider with an audited no-logs policy, because you're moving your trust from your internet provider to the VPN. Most importantly, don't grab a random free one — Proton VPN's free tier is the standout exception — unlimited, audited, and funded by its paid plans rather than by selling your data.
The bottom line
A VPN is one useful tool, not a force field. Pair it with the things it doesn't cover, and you've got real protection.
FAQ
VPNs, answered honestly
Do I actually need a VPN?
Sometimes — not always. A VPN is genuinely useful on untrusted Wi-Fi (airports, cafés, hotels), if you want to stop your internet provider from logging which sites you visit, or to access content from another country. But it's not a blanket 'security' tool, and you don't need it running 24/7 for everyday browsing on your own trusted network with HTTPS sites.
Does a VPN keep me safe from hackers and viruses?
Not really — that's the most common myth. A VPN encrypts your connection, which helps on sketchy Wi-Fi, but it does nothing against malware you download or a phishing site you log into. For those you need antivirus, a password manager and good habits. A VPN protects your connection, not your decisions.
Will a VPN make me anonymous?
No. It hides your IP from websites and your traffic from your provider, but you remain logged into your accounts, your browser still carries cookies and a fingerprint, and the VPN company can see which sites you connect to (even if HTTPS keeps the page contents encrypted). That's why an audited no-logs policy is essential, and why 'total anonymity' VPN ads are overselling.
Is a free VPN good enough?
Only a trustworthy one — and most aren't: more than 60% of free VPN apps raise privacy concerns (CNET research), because if you're not paying, the economics push the provider to monetise you instead — logging and selling your browsing data, injecting ads, or even renting your device out as an exit node for other people's traffic. The honest exception is Proton VPN's free tier is the standout exception — unlimited, audited, and funded by its paid plans rather than by selling your data. If you want free, use that — and steer clear of no-name 'free unlimited' apps.
