VPN Buying Guide: Features That Actually Matter
By NorwegianSpark Editorial · Published June 1, 2026 — written with AI assistance and reviewed by the NorwegianSpark SA editorial team.
Once you have understood that a VPN is about trust and privacy, the next question is which features genuinely matter and which are marketing filler. The feature list on a VPN site is long on purpose; only a handful of items should actually drive your choice.
The essentials are few. A modern protocol (WireGuard or equivalent) for speed and security; a reliable kill switch that blocks traffic if the VPN drops, so you are never silently exposed; enough simultaneous device connections for your household; and apps for every platform you use. Server count matters less than people think — what matters is having fast servers where you actually need them. Providers like PrivateVPN and PureVPN compete on exactly these practical features, so compare them on protocol, kill switch and device limits rather than on raw server numbers.
The gimmicks to discount: enormous server counts, vague "optimised" servers, and bundled "extras" you will never configure. Pay for reliability and the core features, not the longest list.
Price strategy is its own skill. VPN pricing is built around long multi-year commitments at steep discounts that renew at much higher rates — note the renewal price, not just the intro price. This is the same scepticism we apply across the site, from choosing the best VPN to evaluating cheap software keys. And remember a VPN is only one layer alongside antivirus.
Buy Against a Job, Not a Feeling
A VPN is a tool with a specific function: it encrypts your traffic to the provider and presents their address to the sites you visit. Which features matter depends entirely on why you want one:
| Your reason | What actually matters |
|---|---|
| Safety on public or hotel networks | Reliable connection, automatic connect, kill switch |
| Hiding activity from your home network provider | Audited no-logs policy, jurisdiction |
| Appearing to be in another country | Server locations, and honesty about them |
| Cutting tracking and advertising | Very little — this is a browser problem |
| Torrenting | Permitted use, port forwarding, kill switch |
| Working around censorship | Obfuscation, and a provider with a track record |
The fourth row is where most disappointment comes from. A VPN does not stop tracking by accounts you are logged into, by cookies, or by fingerprinting — that is covered in ad blockers and tracker blocking and browser fingerprinting explained.
The Specifications That Are Not Marketing
- Protocol. Modern options are fast and secure; anything older is a reason to ask why.
- A kill switch that is on by default, and which you have tested by disconnecting deliberately and confirming traffic actually stops.
- DNS handled by the provider, so lookups do not leak to your network provider. Test this after connecting.
- Simultaneous device count, which is where tiers actually differ for households.
- An independent audit, and importantly its date and scope. An audit from years ago of a different part of the service is not evidence about today.
The No-Logs Claim, Assessed Honestly
Every provider claims it. What separates them:
- Independent audits, recent, with a published scope.
- Jurisdiction, which determines what a provider can be compelled to do and whether they can tell you about it.
- Infrastructure design — diskless or memory-only servers make retention harder as a matter of architecture rather than of policy.
- Track record in real cases, where a provider has been asked for data and the outcome is a matter of public record.
Treat an unaudited claim as a claim.
The Pricing Trap
Almost every deal in this category is a long-term prepayment at a large discount that renews at a much higher rate. Before buying:
- Find the renewal price, not the introductory one, and decide on that number.
- Check the refund window and what it actually requires.
- Diarise the renewal date the day you buy.
- Be sceptical of free tiers. Running a VPN network costs money, and a free service is monetised somehow — the honest ones are limited free tiers of a paid product.
For the privacy-first shortlist, see the best VPN for privacy; for using one on untrusted networks specifically, public wifi safety.
Buy on protocol, kill switch and device count — and always check the renewal price. General guidance, not advice for a specific threat model.
