Using a VPN, all data traffic is confined to a private, encrypted tunnel until they reach the public Internet. Destinations cannot be accessed until after the end of the VPN tunnel is reached. VPN services are quite useful in workplaces, especially for those who use mobile devices in accessing data from a work server. However, the most common use of VPN software is to remain anonymous to ISPs, websites or governments. This is true for users who download files illegally, such as in the case of copyrighted torrent files.
In the most recent round of testing, we've also looked at how many virtual servers a given VPN company uses. A virtual server is just what it sounds like—a software-defined server running on server hardware that might have several virtual servers onboard. The thing about virtual servers is that they can be configured to appear as if they are in one country when they are actually being hosted somewhere else. That's an issue if you're especially concerned about where you web traffic is traveling. It's a bit worrisome to choose one location and discover you're actually connected somewhere else entirely.
That said, many VPN providers are based outside the US, which complicates enforcement. Jerome continued: “Users can file complaints in a local jurisdiction, and local data protection laws may have more effective enforcement mechanisms. For example, privacy and confidentiality of communications are fundamental rights in the European Union. Data protection authorities in EU-member states are empowered to handle complaints brought by individuals and then provide users with information about the outcome of any investigation. But it is unclear how effective any of these remedies will be.”

Welcome to the CNET 2019 Directory of VPN providers. In this directory, we're taking a look at a few of the very best commercial VPN service providers on the Internet like CyberGhost, IPVanish, Hotspot Shield, Private Internet Access and others. Rather than looking at the wide range of free providers, which often have a lot of limits (and dubious loyalties), we are looking at those vendors who charge a few bucks a month, but put your interests first, rather than those of shadowy advertisers and sponsors. Our VPN rankings are based more than 20 factors including number of server locations, client software, dedicated and dynamic IP, bandwidth caps, security, logging, customer support and price.
