Best VPN: How to Choose by Criteria, Not Rankings

Are "best VPN" rankings trustworthy?

Rarely, and the reason is structural. Comparison sites, video channels, and forum posts earn a commission on every subscription they refer, so the order of a list tracks affiliate contracts more closely than security. Several of the biggest brands also share parent companies, which makes head-to-head comparisons between them less useful than they look.

The VPN market runs on some of the most generous affiliate programs online, and the "top picks" shift as those contracts change.

None of this means those services are bad. It means a position in a ranking is not evidence of quality, and a badge that says "editor's choice" tells you about the editor's revenue, not your security. Objective criteria are evidence. The rest of this guide is about which ones to apply and how to check them without taking anyone's word for it.

The seven VPN comparison criteria that matter

Below are the seven things worth checking for any provider, in roughly the order they matter. Most of them can be verified from the provider's own website before you pay anything; the rest take a few minutes with the service running on your device.

One theme runs through all seven: prefer what is written down and measurable over what is advertised. A protocol has a name, a logging policy has a text, a status page has data. "Military-grade encryption" and "blazing fast" have neither.

• Protocol: WireGuard as the default. Small codebase, modern cryptography, fast reconnection. OpenVPN and IKEv2 are acceptable; PPTP is not acceptable under any circumstances.
• Logging policy: written, specific, and consistent with how the product works. A paid service that limits devices has to store something (an account, a payment, a device key); what matters is that it does not store the sites you visit, your DNS queries, or your traffic.
• Jurisdiction and transparency: who the company is, where it operates, and how it responds to requests from authorities.
• Real-world speed: not the number in the ad, but the latency to the server nearest you. One location close to where you live does more for you than "thousands of servers" spread across the globe.
• Devices: how many per subscription, whether each gets its own key, and whether you can revoke one device without touching the others.
• Payment and cancellation: prices in a currency you understand, a payment method you actually have, cancellation in one click, and a refund policy you can read before you buy.
• Support and status: a support channel that answers and a public status page that shows whether the servers are up right now.

Tests you can run yourself

You do not have to trust a review, or a provider, to verify the basics. Each test below is quick and needs nothing more than a browser. Run them with the VPN connected, then again with it off, and compare the two results.

If a service fails the leak tests, the rest of the comparison is moot: a VPN that exposes your real IP or your DNS queries is not doing the one job you pay it for. If it passes, the speed and reconnection tests tell you whether you will actually keep it switched on day to day.

• IP leak: open any site that displays your public IP. It should show the server's address and country, not yours.
• DNS leak: run a DNS leak test. The resolvers listed should belong to the tunnel, not to your internet provider.
• IPv6 leak: if your network has IPv6, confirm that your IPv6 address is also hidden or disabled while the tunnel is on.
• Speed: measure latency and throughput without the VPN, then with it, on the nearest server. The latency difference should be small; the throughput difference depends on your own connection.
• Reconnection: switch from Wi-Fi to mobile data and back. The tunnel should come back on its own without you touching anything.

Is there a "best free VPN"?

Only in one narrow sense: a limited free tier from a company whose paid product you could name, with the same logging policy and an explicit data or location cap. Everything else that costs nothing is funded by ads, by data sales, or by renting out your connection, and should be avoided.

There are two kinds of free VPN, and they should not be confused. The first is a limited free tier from a serious company: capped data, few locations, and the same logging policy as the paid product. That kind is fine for a trial. The second is an app that costs nothing because it earns money from ads, from selling your browsing data, or from renting out your connection to strangers. That kind should be avoided outright.

Our guide on free VPNs goes through the revenue models and the documented incidents in detail. The short version: for most people, an inexpensive paid VPN with a real refund window is safer than any free one, because the company's income comes from your subscription and not from what you do inside the tunnel.

What SuaVPN offers, and what it does not

In the interest of applying the same criteria to ourselves: SuaVPN runs WireGuard on every server, publishes a detailed written logging policy, limits each plan by device count, with an individual key per device that you can revoke on its own, and keeps a public status page with measured data. The locations you can connect to are listed on that page before you subscribe, and new ones appear there as they are added.

Plans differ only in device count: Basic with 3, Pro with 5, Family with 10. Current prices are on the pricing page. Payment is by card through Stripe, in Brazil or abroad, and the subscription renews on its own. You can cancel at any time, and under Brazilian consumer law you have seven days from purchase to request a full refund.

What we do not offer is just as relevant to a comparison. There is no SuaVPN app: you use the official WireGuard app, which is free and open source, and import a profile from your dashboard by QR code or .conf file; the step-by-step guides for each platform are on the apps page, with walkthroughs for Windows, Mac, Linux, Android, and iPhone. There is no browser extension, no dedicated IP, no split tunneling, and no business plan. We do not promise access to any streaming catalog, we do not promise anonymity, and we do not publish speed figures we have not measured. If any of those points is decisive for you, weigh it accordingly.

How to decide

Start from your own needs, not from a list. Write down what you actually require: a server in a specific country, a certain number of devices, a payment method you have, a price in a currency that suits you. Eliminate every provider that fails one of those. Then apply the seven criteria to whatever is left and run the leak tests on your shortlist.

Finally, use the refund window as your real test. A week of ordinary use, on your own connection, with your own devices, tells you more than any ranking can. If the tunnel stays up, the speed is acceptable for what you do, and support answers when you write to support, you have found your best VPN, whichever name is on it.
