Two networks can be connected over an intranet using a site-to-site VPN connection. This type of VPN connection might be necessary, for example, for two departments in separate locations, whose data is highly sensitive, to communicate with each other. For instance, the finance department might need to communicate with the human resources department to exchange payroll information.
If you’re an online gamer who uses a VPN to access another region’s servers (or because you got IP banned), the most important factor in choosing a VPN is latency. The ping time between the game servers and your computer or console is mostly what determines how much lag you’ll experience. If you want to stay competitive, figure out where the game’s regional servers are hosted and choose the nearest VPN server.

Every VPN will tell you it is does not track your internet activity or is a “zero logs” VPN. In reality, delivering high performance across an extensive global network is impossible unless you are monitoring at least some connection details of your users. You could read a ton of privacy policies and terms of service to find out exactly what’s collected and for how long it’s stored or let us do that for you and just check the logging policy section of our review that explains this in plain language. Ideally you want a VPN that does not log your IP address at all and limits timestamp logging to just the date of your connection.

We tested each service using both the Netflix-operated download speed test and the more comprehensive Internet Health Test; the latter measures speeds up and down through multiple interconnection points between Internet providers. We ran each test on the macOS version of each VPN software in its default configuration, with our test computer connected over Gigabit Ethernet to a cable modem with no other traffic running through it. We recorded baseline download rates without a VPN active of nearly 300 mbps, and we checked our non-VPN speeds at random intervals to ensure that our local ISP wasn’t affecting the tests.
Netflix blocking paying customers might seem odd, but it's all about regions and not people. Just because you paid for Netflix in one place does not mean you're entitled to the content available on the same service but in a different location. Media distribution and rights are messy and complicated. You may or may not agree with the laws and terms of service surrounding media streaming, but you should definitely be aware that they exist and understand when you're taking the risk of breaking them. Netflix, for its part, lays out how that it will attempt to verify a user's location in order to provide content in section 6c of its Terms of Use document.
While you're connected to a VPN, all your network traffic passes through this protected tunnel, and no one—not even your ISP—can see your traffic until it exits the tunnel from the VPN server and enters the public internet. If you make sure to only connect to websites secured with HTTPS, your data will continue to be encrypted even after it leaves the VPN.
