Questions people ask
Does a VPN make me anonymous?
No. A VPN hides your traffic from your network and your internet provider, and it swaps your real IP address for the VPN server’s.
That is privacy, not anonymity. Websites can still recognise you through the accounts you log in to, cookies and your browser’s fingerprint, and the VPN company can see your traffic unless it has a no-logs policy you trust.
Look for one that outside auditors have checked.
If you want more protection, some providers route traffic through two servers, such as Surfshark’s MultiHop and Proton VPN’s Secure Core. For real anonymity you would also need to change how you browse, not just add a VPN.
Will a VPN slow down my internet?
A little, because your traffic takes a detour and has to be encrypted. On a good provider the slowdown is small.
In Security.org’s 2026 tests, Proton VPN cut download speeds by about 8% at most, and it rated NordVPN and Surfshark similarly.
You can keep speeds high by connecting to a server close to you, using the provider’s fastest protocol (NordLynx on NordVPN, Lightway on ExpressVPN), and using a wired or strong Wi-Fi connection. The free Proton plan runs at medium speed by design.
Is using a VPN legal?
In most countries, yes. A small number of countries restrict or ban VPNs, so check the rules where you live and where you are travelling.
A VPN does not make illegal activity legal.
Also read the terms of any service you use it with. Streaming services often forbid VPN use to watch content that is not licensed in your region, and they may block VPN connections.
Is there a free VPN worth using?
Proton VPN is the only one of these four with a permanent free plan. It has no data limits and no ads, but it covers one device at a time, runs at medium speed, and connects to servers in 10 countries that are chosen for you.
Streaming and P2P need a paid plan.
NordVPN, ExpressVPN and Surfshark have no free plan, but each has a 30-day money-back guarantee, so you can test one and get a refund. ExpressVPN limits its guarantee to new users.
Surfshark also mentions a free trial on its site, so check whether one is available for your device.
Be careful with other free VPNs. Some earn money by tracking your activity or showing ads, which defeats the purpose.
Can I get my money back?
All four offer a 30-day money-back guarantee, but ExpressVPN limits it to new users. The others apply it to their paid plans.
Read the current terms before you buy, since they can change.
