What does a good VPN do?

Now that you know the advantages of using a VPN, as well as its various types, protocols, and use cases, let's explore what to look for in a VPN provider. There are plenty of options on the market, but you'll want to select a reputable company with clear expertise, a proven track record, and trustworthy values. Here are some of the features you should look for in a good VPN provider:

Strong protocols

The most important feature of any VPN provider is security, so it's essential to choose a service that uses an industry-standard protocol with 256-bit encryption—the same kind of encryption used by banks and military. In today's landscape, this means being aware of the limitations of older protocols like L2TP/IPSec, while avoiding obsolete protocols like PPTP altogether. Instead, opt for services that use OpenVPN, SSTP, IKEv2/IPSec, or WireGuard. The top providers support multiple protocols and should allow you to toggle between them, depending on the use case.

IP address protection

Greater anonymity is a pivotal reason to use a VPN. When looking for a provider, you'll want to choose one that provides you with options for rerouting your IP address. A shared IP address groups multiple users together under one IP, protecting you from within the crowd, while quick and easy server switching allows you to choose your location from wherever your provider's servers are located.

A range of servers across many locations

When using a VPN, you may notice a slowdown in performance if your provider only runs a select number of servers in a select number of locations. By using a service comprised of many servers located near and far, including ones closer to you, your data travels a shorter distance, improving on speed. The more servers there are around the world, the more spread out the users, the faster the performance. And if you're looking to switch to an IP address from a particular region, you'll want to see that your provider has a server there that supports your chosen protocol.

Zero-log policy

You may be hidden from third parties, but in theory, a VPN provider has the power to potentially see everything you do under its protection. Because of this, it's important to go with a company that practices transparency around their logging policy. A zero-log, or no-log VPN provider keeps a record of your email address, payment information, and VPN server, but it shouldn't log or store any data that gets sent while you're securely connected. This includes usage logs, connection logs, session data, or even your IP address.

Kill switch

If your secure VPN connection gets interrupted, your computer reverts to your real IP address, in turn compromising your identity. A kill switch prevents this from happening by cutting off your Internet connection as soon as your VPN connection disrupts.

Mobile compatibility

Mobile activity gets risky when it's happening on an unsecured Wi-Fi network. If you're looking for a safer mobile experience, then it may be useful to look for a provider that offers support for mobile VPN, particularly the ability to switch to the IKEv2/IPSec protocol when roaming. This ensures that your connection is secure, even when you move from public Wi-Fi to cellular data.

Options for authentication

When a computer attempts to connect to a VPN server, the VPN must first authenticate the user before the connection is successful. This typically means entering your credentials via a login page or desktop client, though it's best to consider additional options for authentication. Multi-factor authentication, for instance, requires that you authorize your login with your mobile device through an app. You may also want to use a physical security key, which you plug into your USB port, for even more security.

Customer support

Like other software companies, a VPN provider must have a reliable support team for you to contact for any issues that may arise. This support team should be knowledgeable, helpful, and easy to get in touch with.

Premium pricing

In general, it's best to avoid free VPNs altogether. By choosing a paid provider, you are choosing a real and credible company, backed by quality technology and infrastructure. A paid provider is also less likely to log your activities and sell that information to advertisers. A premium VPN may require a monthly fee, but the value of safety, security, and peace of mind is well worth the cost.
