Every VPN website promises military-grade encryption and total anonymity. Those words cost nothing to print, which is why they are useless for comparison. To choose a secure VPN you need to look at things a provider cannot claim without evidence: independent audits, where the company is based, what happens when the connection drops, and what you will really pay after the first term. Here are the seven checks worth making, in order.

1. Has the no-logs policy been audited?
An independent firm checking the servers and asking staff what is stored is the strongest evidence available. Look for a named auditor, a recent date and a report you can read. Proton VPN publishes yearly audits, NordVPN has been assessed several times by Deloitte, and ExpressVPN has had multiple audits. A provider with no audit is not automatically bad, but you are taking its word for everything.
2. Where is the company based?
Jurisdiction decides which authorities can demand data and whether the company can be told to start logging. Switzerland and Panama are popular choices for privacy reasons; a US or EU base is not disqualifying, especially with an audited no-logs policy, but it is worth knowing. Check the ownership too: several well-known brands belong to the same group, and one company owning many “independent” VPNs is worth taking into account.
3. Which protocols does it offer?
WireGuard, or a provider’s implementation of it, is fast and modern. OpenVPN is older but well understood and useful where WireGuard is blocked. Avoid services that only offer PPTP, which has been considered insecure for years. An obfuscation or “stealth” mode is valuable if you travel to countries that block VPNs.
4. Is there a kill switch, and does it work?
A kill switch blocks traffic when the VPN drops, so your real address is not exposed while you are not looking. Turn it on and test it: connect, then stop the VPN service from the app and see whether pages still load. If they do, the feature is not doing its job.
5. What does the privacy policy actually say?
| Phrase in the policy | What to make of it |
|---|---|
| “We do not log browsing activity” | Good, if an audit backs it up |
| “We collect connection timestamps and bandwidth” | Common, but more than the strictest services keep |
| “We may share data with partners for marketing” | Walk away |
| No policy, or one with no company name | Walk away |
6. What happens to the price at renewal?
The headline price almost always belongs to a two- or three-year plan paid in advance, and the renewal is higher. Before subscribing, find the renewal rate, check whether the refund period is 30 days, and note the date in your calendar.
7. Does the free plan make sense?
Running servers costs money, so ask how a free service pays for itself. Proton VPN funds its free plan from paid subscriptions and says so; other free services sell data, show ads or route traffic through users’ devices. If you cannot tell how a free VPN earns money, assume you are the product. Our comparison of free VPN extensions lists the trade-offs for ten of them.
Frequently asked questions
Does a VPN make me anonymous?
No. It hides your address from websites and your traffic from your network, but accounts you sign in to still identify you.
Is a more expensive VPN more secure?
Not necessarily. Audits and clear policies matter more than price; several mid-priced services score better than premium brands.
