Even TunnelBear's network performance and pricing are just about average compared to other services we've reviewed, except that you can pay with literal jars of honey. The company takes security and privacy seriously, explaining its policies and protocols in plain English, and you can read the results of two third-party security audits on the company website.
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.
A VPN is created by establishing a virtual point-to-point connection through the use of dedicated connections, virtual tunneling protocols, or traffic encryption. A VPN available from the public Internet can provide some of the benefits of a wide area network (WAN). From a user perspective, the resources available within the private network can be accessed remotely.
The virtual router architecture, as opposed to BGP/MPLS techniques, requires no modification to existing routing protocols such as BGP. By the provisioning of logically independent routing domains, the customer operating a VPN is completely responsible for the address space. In the various MPLS tunnels, the different PPVPNs are disambiguated by their label, but do not need routing distinguishers.
VPN.ac is a security-focused provider that is based in Romania. It was created by a team of network security professionals with an emphasis on security, strong encryption, and high-quality applications. Their network is composed entirely of dedicated, bare-metal servers that offer great performance, as seen in the latest speed tests for the VPN.ac review.
For the most part, VPN clients are the same for both Windows and macOS. But that's not always the case, and I have found marked performance differences depending on the platform. I have split out reviews of Mac VPN applications, in case you're more into fruit than windows. Note that you can skip client apps altogether and connect to the VPN service simply using your computer's network control panel. You'll still need to sign up with a VPN service, however.
Before anything else, understand that if you want to use a VPN you should be paying for it. Free VPNs are either selling your browsing data in aggregated form to researchers and marketers, or giving you a paltry amount of data transfer every month. Either way, a basic rule of thumb is that a free VPN will not protect your privacy in any meaningful way.
CyberGhost has been around since 2011 and has come out strongly as a supporter of "civil rights, a free society, and an uncensored Internet culture." We really liked how the company specifically showcases, on their Web site, how folks normally prevented from accessing such important services as Facebook and YouTube can bring those services into their lives via a VPN.
