A VPN encrypts all of the Internet traffic between your computer and the VPN server, preventing anyone on your local network, or connection points along the way, from monitoring or modifying your traffic. Beyond the VPN server (in other words, on the rest of the way to whatever Internet server you’re connecting to), your traffic mixes with traffic from other people on the VPN and the rest of the Internet. Ideally, that makes your traffic traceable only to the VPN server, not to your home, office, or computer. You can read a more detailed explanation in our post about what a VPN is and when using one makes sense.
If you're using a service to route all your internet traffic through its servers, you have to be able to trust the provider. Established security companies, such as F-Secure, may have only recently come to the VPN market. It's easier to trust companies that have been around a little longer, simply because their reputation is likely to be known. But companies and products can change quickly. Today's slow VPN service that won't let you cancel your subscription could be tomorrow's poster child for excellence.
A VPN client on a remote user's computer or mobile device connects to a VPN gateway on the organization's network. The gateway typically requires the device to authenticate its identity. Then, it creates a network link back to the device that allows it to reach internal network resources -- e.g., file servers, printers and intranets -- as though the gateway is on the network locally.
As YouTube and Netflix make more money, the distribution models become more complex. For example, Annihilation — an instant sci-fi classic, according to your writer — was released in theaters in the U.S., but released exclusively through Netflix in the U.K. and Australia. Similarly, season four of Better Call Saul aired on AMC in the U.S., while new episodes in the U.K. aired on Netflix.
My recommendation, and the protocol I most often choose to use, is OpenVPN. OpenVPN is a non-proprietary, open-source implementation of a VPN communication layer protocol. It's well-understood, well-regarded, generally quite secure, and robust. In addition, it has the benefit of being able to communicate over port 443, which is the standard port for https communication, which means almost all firewalls will allow OpenVPN traffic -- and most won't even be able to detect that a VPN is being used.
IPVanish slows down Internet speed, but only by a very little margin. It claims to be the World’s fastest VPN, but that is arguable. It offers unlimited bandwidth. However, if you are looking for a quick support, note that IPVanish does not provide such. On the support page there is a note that states that a backlog of up to a day and a half might occur. If you are a business that relies heavily on Internet, that is a downside to be considered.
These folks have been around since 2010, and don't log anything. They provide a generous five connections, a connection kill switch feature, and some good online documentation and security guidance. Our one disappointment is that their refund policy is 7-days instead of 30, but you can certainly get a feel for their excellent performance in the space of a week.
