VPN Explained: Do You Actually Need One?
VPN ads are everywhere. They promise total online privacy, military-grade encryption, and protection from hackers. Most of that is marketing. Here's what VPNs actually do and when you actually need one.
Short answer
VPNs are useful for: public Wi-Fi, watching international content, bypassing some firewalls. They are NOT a magical shield against hackers, viruses, or tracking. Don't pay $13/month for one.
What a VPN actually does
VPN stands for Virtual Private Network. When you use one:
- Your device connects to a VPN server (somewhere else in the world)
- All your internet traffic gets routed through that server
- Websites see the VPN server's IP address, not yours
- The traffic between your device and the server is encrypted
What a VPN does NOT do
- Make you anonymous. The VPN provider sees everything. If they keep logs (some do, some don't), they could share with law enforcement
- Stop you from being tracked. Cookies, fingerprinting, and logged-in accounts (Google, Facebook) still know it's you
- Protect you from malware. A VPN doesn't scan files. You still need antivirus
- Stop phishing. If you click a scam link, the VPN doesn't help
- Speed up internet. VPNs usually slow you down 5-30%
When a VPN is genuinely useful
1. Public Wi-Fi
Coffee shops, airports, hotels. Other users on the same network could potentially see some of your traffic. With a VPN, your traffic is encrypted from the start.
That said: modern HTTPS (the lock icon in your browser) already encrypts almost everything. VPN adds another layer.
2. Bypass geo-blocked content
Want to watch a show that's only on UK Netflix? Set VPN to UK. Many streaming services try to block this, but it works often.
3. Hide your IP from a specific site
If you're worried about a specific site tracking your location or IP.
4. Get around censorship
If you're traveling somewhere that blocks certain websites (China, Iran, parts of the Middle East), a VPN can route around blocks.
5. Use a network you don't trust
If you work in an office that monitors traffic, or you suspect your ISP is throttling streaming, a VPN hides what you're doing.
Free VPNs: usually a bad idea
If a VPN is free, you're the product. Free VPNs often:
- Sell your browsing data
- Inject ads into web pages
- Throttle speeds to push you to a paid tier
- Use weak encryption
- Log everything
Exceptions: ProtonVPN free, Cloudflare WARP, and Mullvad's free trial are run by legitimate companies with paid business models.
Recommended paid VPNs (2026)
- Mullvad: $5/month flat, no email needed, no logs, Sweden-based
- ProtonVPN: $5-10/month, Switzerland-based, free tier available
- IVPN: $6/month, Gibraltar-based, no logs
- Cloudflare WARP: free + paid tiers, fast, technically not a "privacy VPN" but encrypts traffic well
Skip: NordVPN, ExpressVPN, Surfshark. Not bad services, but the constant influencer ads inflate the prices. They charge $13-15/month for the same thing Mullvad charges $5 for.
How to set up a VPN
- Sign up for the service (Mullvad doesn't even require email)
- Download the app for your platform (iOS, Android, Mac, Windows)
- Sign in with your account number or login
- Choose a server location
- Click Connect
Most VPN apps have a "Connect to fastest server" button. Use that 90% of the time.
VPN on your phone
iPhone: download the VPN app from App Store. You'll be prompted to allow VPN configuration.
Android: same. App Store / Play Store, install, allow.
Both: you can usually toggle the VPN on/off from a widget or settings shortcut.
VPN on your home router
Some routers support running a VPN at the router level, so every device in your home goes through it without per-device setup. Asus, GL.iNet, and Vilfo routers support this. Slower but convenient.
Verdict
Most people don't strictly need a VPN at home. Your bigger threats are:
- Phishing emails
- Weak passwords
- Old, unpatched software
- Sketchy app downloads
If you spend time on public Wi-Fi or want to bypass geo-blocks, get a $5/month VPN like Mullvad. Otherwise, your money is better spent on a password manager and a backup drive.
