Decoding VPNs: An All-Inclusive Guide to Our Testing and Evaluation Process

Read Time:3 Minute, 35 Second

In today’s digital world, virtual private networks, or VPNs, have become commonplace, offering the promise of protecting your online privacy and opening you a vast array of information. With so many VPN choices available on the market, it may be difficult to separate marketing hype from actual product. In 2023, we at Engadget set out to conduct an unbiased assessment of VPNs, taking into account variables such as cost, use restrictions, performance, latency, and security. We’ll walk you through our rigorous testing procedure in this in-depth guide to assist you in selecting a VPN with knowledge.

Gaining Knowledge About VPNs:

VPNs operate as barriers for your virtual persona, offering an additional degree of protection by disguising your IP address and redirecting your data via distant servers. This helps get over geoblocking methods and access content that is limited to a certain location in addition to guaranteeing privacy. It’s important to remember, though, that even while a VPN increases security, other essential cybersecurity procedures like multifactor authentication and strong passwords should still be used in addition to the VPN.

Our Standards for Testing:

We at Engadget are aware that selecting a VPN needs considerable thought. For this reason, we’ve created a thorough testing procedure to assess several facets of every service. Our review includes background checks, setup instructions, use caps, latency and speed measures, efficacy of geoblocking, and leak detection.

Background Verifications:

We start our assessment by thoroughly researching the history of each VPN service provider. We closely examine the company’s security incident history, transparency reports, privacy policies, and security audits. Through citation of reliable resources such as VPNalyzer and Consumer Reports, we guarantee a thorough comprehension of the security features offered by each service.


We evaluate VPN setup procedures for ease of use and intuitiveness. Analyzing compatible platforms—ranging from web browsers to Smart TVs—enables us to assess how accessible each service is. We offer insights into the setup process to help you select a VPN that works flawlessly with your devices, regardless of whether a VPN connects automatically or needs extra steps.

Usage Restrictions:

We examine the specifics of every VPN provider’s terms of service, even when they make claims of being compatible with all devices. We look into fair use guidelines, the maximum number of devices that may connect at once, and whether or not premium plans are the only way to access advanced services. We confirm that the vendors’ assertions about device usage are accurate by running targeted testing concurrently.

Latency and Speed:

It is essential to test the latency and speed of VPNs in order to evaluate their performance. Before using the “quick connect” tool to get the quickest provider available, we establish a baseline connection. We give average speed and ping statistics, comparing results with the baseline, using Ookla speed testing and ping tests. This makes it possible for people to comprehend how using a VPN affects their internet speeds.


We test VPNs from within the US to see how well they can get around geoblocking. We attempt to access region-specific material on sites such as Netflix, YouTube, and gaming servers by establishing connections with servers located in Canada, Hong Kong, and the UK. In addition to verifying access, our objective is to find any possible delays or problems that consumers could have when utilizing these services.

Examining Leaks:

Since security is our first priority, we constantly monitor any DNS and WebRTC breaches that can jeopardize your privacy. Unencrypted requests that are transmitted outside of the VPN’s encrypted tunnel might cause DNS leaks, which could reveal your online activities. Your IP address may be made public on websites due to WebRTC leaks. By using tools like ExpressVPN’s leak testing and NordVPN’s IP address search, we make sure that the VPN finds and fixes these flaws both before and after connection.

Selecting the best VPN needs thought, and at Engadget, we’re dedicated to giving you accurate and thorough information. Our goal is to enable people to make well-informed decisions regarding their online security and privacy by carefully testing and evaluating VPNs. As the world of virtual private networks continues to change and we continue to investigate and evaluate new offerings, be sure to check out our often updated list of the Best VPNs.
