What a VPN Does and What It Does Not

The actual mechanism, public wifi, privacy claims and choosing one

VPNs are marketed on security and used mostly for something else, and separating the two makes the decision straightforward.

What it actually does

A VPN encrypts traffic between your device and the provider's server, then sends it on from there. Your internet provider sees that you connected to a VPN and not what you did; the site sees the VPN's address rather than yours.

That is the whole mechanism. It moves trust from your network operator to the VPN company rather than removing it.

Public wifi

The classic argument is weaker than it was. Almost all websites now use HTTPS, which already encrypts the content, so an attacker on a café network sees which sites you visit rather than what you type.

A VPN still hides that list, which is a real if narrower benefit.

What it does not do

It does not make you anonymous. Logging into an account identifies you regardless. Browser fingerprinting, cookies and payment details all work as before.

It does not stop malware, phishing or a scam call. It does not protect an account with a weak password.

Logging and jurisdiction

The provider can see what your internet provider would have seen, so the policy and who audits it matter more than the feature list. Look for independently audited no-log claims and check where the company is based.

Operating a free VPN has costs; check how a provider funds its service and handles user data.

Streaming and regions

Widely used for this and frequently against a service's terms. Speeds drop and access is blocked and restored constantly.

When one is genuinely useful

Connecting to a work network remotely, using a network you have no reason to trust, avoiding tracking by an internet provider, and accessing a home service while travelling.

Journalists, researchers and people in countries that filter the internet have far stronger reasons than most consumers.

Choosing one

An independently audited no-log policy, a published jurisdiction, a clear ownership structure and reasonable speeds. Check the renewal price, since the advertised figure is usually a long first term.

Check how many devices a subscription covers and whether the apps are maintained for the platforms you use.

Speed

Expect some loss, more on distant servers. A nearby server generally gives the best result.

Privacy beyond a VPN

A browser that blocks trackers, separate accounts for separate purposes, and reviewing app permissions do more for everyday privacy than routing traffic elsewhere. Most tracking follows the account rather than the address.

Check what a service already knows about you before paying to hide it from someone else.

What matters more

Updates, unique passwords in a manager, two-factor authentication and backups.
