VPN Frequently Asked Questions

A VPN encrypts the connection between your device and the internet, hiding your activity from your network provider and masking your location. It adds a useful layer of everyday privacy, but it does not make you fully anonymous.

In most countries, using a VPN is perfectly legal. A handful of places restrict or ban them, so it's worth checking the rules where you live or travel. Whatever you do online still has to follow the law.

A little. Encryption always adds some overhead, but a good VPN keeps the drop small enough that you won't notice it for browsing or HD video. Choosing a nearby server helps keep speeds high.

Often, yes. A VPN can help you reach libraries from other regions, though results vary by platform and change over time. See our dedicated streaming guide for our current picks.

It depends on the provider. Most allow somewhere between seven and ten devices at once; Surfshark allows unlimited. Check the device limit before you buy if you have a full household.

Some are fine for light use, but many fund themselves by logging or selling data, which defeats the purpose. If you go free, choose a reputable provider with a clear privacy policy — ProtonVPN's free plan is a trustworthy example.

It means the provider does not record what you do while connected. The strongest no-logs claims have been verified by an independent auditor, so you're not just taking the company's word for it.

A kill switch cuts your internet connection if the VPN unexpectedly drops, so your real location and traffic don't leak in the gap. We consider it an essential feature.

Monthly plans are the most flexible but cost the most per month. Longer one or two-year plans bring the monthly price down significantly. Pick based on how long you realistically expect to use it.

For most people, NordVPN is the best all-round pick. If value matters most, look at Surfshark; for privacy, ProtonVPN; for simplicity, ExpressVPN; for beginners, CyberGhost. Our buying guide and comparison table can help you decide.
