VPN ads make it sound like you’re unsafe online without one. The truth is more useful: a VPN is a great tool for specific situations, and unnecessary for others. Here’s what it actually does.
What a VPN does, in plain English
A VPN (virtual private network) creates an encrypted tunnel between your device and a server run by the VPN company. Two things change:
- Your internet traffic is encrypted on its way to the VPN server, so people on the same network (like public Wi-Fi) and your internet provider can’t see what you’re doing.
- Websites see the VPN server’s IP address instead of yours, which hides your approximate location.
What a VPN does NOT do
- It doesn’t make you anonymous. If you log in to Google or Facebook, they still know it’s you.
- It doesn’t stop viruses or scam emails on its own. (Some VPNs include extra blocking features, but that’s an add-on.)
- It doesn’t protect weak or reused passwords. A password manager does that.
- It doesn’t make illegal activity legal.
When a VPN is worth it
- Public Wi-Fi: coffee shops, airports, hotels. See How to Stay Safe on Public Wi-Fi.
- Travel: accessing your usual services and keeping your connection private on unfamiliar networks.
- Privacy from your internet provider: if you’d rather they not see which sites you visit.
- Remote work: extra protection when handling work or client data outside the office.
When you can probably skip it
If you’re mostly at home on your own secured Wi-Fi, using sites that show the padlock (HTTPS), a VPN adds less. Most websites already encrypt your connection. In that case, a password manager and good antivirus habits will do more for your safety.
For me, it’s mostly travel and coffee shops when I’m out working. Airports are the big one, I always want a VPN running if I’m on public Wi-Fi there.
Free vs paid VPNs
Be careful with free VPNs. Running servers costs money, and some free apps make it back by collecting and selling data, which defeats the purpose. A reputable exception is Proton VPN, which offers a free plan from a privacy-focused company with paid upgrades. More on this in Free vs Paid Security Software.
What to look for
- Independently audited no-logs policy: an outside firm has checked that the company doesn’t keep records of your activity
- Modern protocols like WireGuard (or the company’s version of it) for speed
- Kill switch: cuts your internet if the VPN drops, so nothing leaks
- Device limit that covers your household
- Money-back guarantee so you can test speed on your own connection
Popular options
- NordVPN: fast, feature-rich, with audited no-logs claims
- Surfshark: known for allowing unlimited devices on one account
- Proton VPN: Swiss privacy focus and a trustworthy free plan

The bottom line
A VPN is a privacy tool, not a magic shield. If you use public Wi-Fi, travel, or work remotely, it’s worth having. If you’re home on your own network, put your money toward a password manager first.
