Choosing a trustworthy, reliable VPN service provider is hard, but over on Reddit, user That One Privacy Guy collected virtually everything there is to know about most large (and many small) VPNs and put them into a single colour-coded Google Sheet that's easy to read and understand.
The sheet is packed with good data, including whether or not the VPN is cross-platform, based in a "fourteen eyes" country (aka, a country that's happy to spy on your data and share information with one another), what kind of logging they do (if any,) what protocols they support and which ports they block, their number of exit servers and how many countries they have them in, and more.
A quick look at even some of the best performing and most popular VPNs will show you it's a mixed bag, whether it's from a privacy perspective or an availability perspective. Either way, the information is right there to look through.
It's tough choosing a good VPN. Sites offer endless discounts, other sites run sponsored posts pushing specific providers they have never actually used or researched, and still other new VPNs appear overnight when someone with a gleam in their eye spins up an Amazon Web Services instance, installs OpenVPN, and starts charging people a monthly subscription fee. We have our favourites obviously (and before you ask, we never take money or anything else in exchange for our recommendations), but if you're on the hunt for a good VPN and have specific criteria, this sheet will definitely help you find the right one for you.
