Servers – The number of servers and geographical distribution of these servers is another important factor that determines the quality of a VPN. The greater the server network, the fewer problems you are likely to encounter such as overcrowded servers and downtime. A strong server infrastructure signifies a high standard of VPN performance standard.
DNS servers are a bit like the phone books of the Internet: You can type in “thewirecutter.com,” for instance, and one of the many DNS servers behind the scenes can point you to the IP address of a server hosting the site. Most of the time, your DNS requests automatically route through your ISP, giving the ISP an easy way to monitor your traffic. Some VPN services rely on third-party DNS servers, but the best ones keep DNS servers in-house to prevent your browsing history, or your IP address, from getting out.
Virtual LAN (VLAN) is a Layer 2 technique that allow for the coexistence of multiple local area network (LAN) broadcast domains, interconnected via trunks using the IEEE 802.1Q trunking protocol. Other trunking protocols have been used but have become obsolete, including Inter-Switch Link (ISL), IEEE 802.10 (originally a security protocol but a subset was introduced for trunking), and ATM LAN Emulation (LANE).
Latency is a measurement of time between when your computer sends a request and when it receives a response. It's often called ping time. Lots of things can affect latency; the distance your request physically travels through fiber has a big impact, for example. Latency is measured in milliseconds, however, so even a large increase may not be noticeable to the average user. Latency is very important when playing video games over a VPN, as lower latency means a more responsive experience with less lag.
Let's start with the basic idea of internet communication. Suppose you're at your desk and you want to access a website like ZDNet. To do this, your computer initiates a request by sending some packets. If you're in an office, those packets often travel through switches and routers on your LAN before they are transferred to the public internet through a router.
Also important is the protocol the VPN service uses. Connecting to a VPN service using the OpenVPN protocol generally yields a faster, more reliable experience. Plus, OpenVPN is, as the name implies, open-source. That means it has been picked over for flaws and exploits by thousands of volunteers. If you're concerned about speed and security, selecting a service that supports OpenVPN and makes it available by default is important.
You might be thinking: “I only need one connection, don’t I?” What if you want to set up VPN access on more than one device, for more than one family member, on your home router, or the like? You’ll need multiple concurrent connections to the service. Or, perhaps, if you’re particularly security oriented, you’d like to configure multiple devices to use multiple different exit nodes so your collective personal or household traffic isn’t all bundled together.
All that being said, some VPNs are still faster than others. During the process, we’ve tested over 45 VPN service providers to share our findings with you. Below you will find the top five fastest VPNs that offer feature-rich experience packed with the high speed. For sure, speed is one of the crucial things we look for before purchasing a VPN, especially when every other provider claims to be the fastest, so consider these providers who managed to cut our speed tests; you can thank us later!
Beyond those two factors, it’s difficult to make blanket statements about what makes a trustworthy VPN. At the bare minimum, a good VPN provider should not collect and keep any logs of its customers’ browsing history. If it does, that puts your privacy at risk should someone access (or even release) those logs without authorization. But deciding when to a trust a logging policy isn’t easy. As the EFF points out, “Some VPNs with exemplary privacy policies could be run by devious people.” You don’t need to have done anything illegal to prefer that law enforcement and criminals alike not have access to a browsing history that may include your bank, medical websites, or that one thing you looked at around 2 a.m. that one time.
A mix of features and price make a good VPN, but plenty of bad VPNs masquerade as good ones. Look for articles written by trustworthy sources that discuss the merits of each service based on its features, versus simple rundowns and user testimonials, which are almost always polluted by a combination of fanatical users and corporate bootstrapping in attempt to get their names out to potential customers.
