What a VPN can and cannot do for your privacy

A VPN moves your traffic through an encrypted tunnel to the provider. That helps in specific situations and does nothing in many others.

What a VPN can and cannot do for your privacyTech

The short answer

  • A VPN encrypts traffic between your device and the VPN server, then sends it on to the wider internet from there.
  • It hides your browsing from the local network and your internet provider, and masks your IP address from sites you visit.
  • It does not make you anonymous, does not stop tracking by accounts you log into, and shifts trust to the VPN operator.
  • Choose a provider on its logging policy and jurisdiction, not on the speed claims in its adverts.

A virtual private network is one of the most oversold tools in consumer security. It does something real and useful, but the marketing routinely implies protections it cannot provide. Understanding the boundary is most of the value.

What it actually does

A VPN builds an encrypted tunnel between your device and a server the provider runs. Whoever controls the network you are on — a cafe, an airport, your internet provider — sees only that you are connected to that server, not which sites you visit. The sites you reach see the VPN server's address rather than yours.

  • Useful on untrusted Wi-Fi, where it stops the local network from inspecting your traffic.
  • Useful for hiding your browsing destinations from your internet provider.
  • Useful for masking your IP address and rough location from the sites you visit.

What it does not do

A VPN does not make you anonymous. The moment you log into an account, that service knows who you are regardless of your IP. It does not stop cookies, browser fingerprinting or ad tracking. And it does not remove trust — it relocates it, from your internet provider to the VPN operator, who can now see your traffic instead.

Used for the narrow jobs it is good at, a VPN is worth having. Treated as a blanket privacy solution, it produces a false sense of security that can be worse than none.
