Is a VPN Worth It?

VPN ads promise protection from everything. The honest answer is narrower: a VPN is very good at a few specific things and useless for others. Here is the list.

What a VPN Does Well

Hides your traffic from your internet provider. Your ISP sees an encrypted connection to the VPN and nothing about what is inside it.
Protects you on public Wi-Fi. Hotel, airport and cafe networks cannot read your traffic through the tunnel.
Hides your home IP address from the sites and services you visit. They see the VPN server's address instead.
Gets around simple network blocks and local snooping, including some school and workplace filters.

What a VPN Does Not Do

It does not make you anonymous. If you log into Google, Facebook or Amazon, they still know it is you.
It does not stop tracking cookies or fingerprinting. Ad trackers follow your browser, not your IP address. See Browser Fingerprinting.
It does not protect against phishing or malware. A scam link is just as dangerous through a VPN.
It does not hide you from the VPN company. You are moving trust from your ISP to them. That is why their logging policy matters more than any feature list.

Who Gets Real Value

People who often use public or shared Wi-Fi, such as commuters, travelers and remote workers
Anyone who does not want their ISP to build a record of the sites they visit. In the US, providers can sell this. See ISP Tracking.
People in a house, apartment or workplace where the network is not theirs

Who Can Probably Skip It

If you only browse from your own home network, use HTTPS sites, and your main concern is ads and trackers, a DNS blocker does more for you than a VPN. See How to Block Ads on Every Device at Home. A VPN and a DNS blocker work well together, but if you can only do one, match it to the problem you actually have.

Choosing One

Look at the logging policy. Does the company say plainly what it does and does not record?
Be wary of free VPNs. Running servers costs money, and if you are not paying, your data usually is the product.
Be wary of the word unlimited. Someone pays for bandwidth. Honest limits are a good sign. See Why Harbor VPN Has Limits.

Common Questions

Does a VPN make me anonymous?

No. It hides your IP address and your traffic from the network, not your identity. Accounts, cookies and device fingerprints still identify you.

Is a VPN safe on public Wi-Fi?

It protects the connection between your device and the VPN server, which stops other people on that network from reading your traffic. Most sites also use HTTPS, so the added benefit is mostly hiding which sites you visit.

Should I leave a VPN on all the time?

For most people, yes, on a phone that moves between networks. Some banking and streaming apps may object to VPN addresses, in which case turn it off for those.

Is a VPN better than a DNS blocker?

They do different jobs. A VPN hides your traffic from the network. A DNS blocker removes ads and trackers. Many people want both.
