A VPN client is software that runs on your device in order to securely connect it to a VPN server. All major platforms (Windows, macOS, Android, iOS, and Linux) come with a built-in VPN client that can be configured manually, although OpenVPN always requires a third party client to be installed. Most VPN services now offer custom clients and apps, which are the easiest way to use their service as they come pre-configured with all the correct settings. They also typically offer a range of funky and useful features that are not available by simply manually configuring the built-in VPN client. To clear up any confusion, a ''VPN client'' and a ''VPN app'' are exactly the same thing. Traditionally, the word client is used for desktop software and the word app for mobile software, but it is becoming increasingly common to talk about VPN apps on the desktop. The terms are interchangeable.
VPNs also cloak your computer's actual IP address, hiding it behind the IP address of the VPN server you're connected to. IP addresses are distributed based on location, so you can estimate someone's location simply by looking at their IP address. And while IP addresses may change, it's possible to track someone across the internet by watching where the same IP address appears. Using a VPN makes it harder for advertisers (or spies, or hackers) to track you online.
If you’re going to use torrents, however, life is easier if you use a VPN—especially if the network you’re on blocks torrenting. There are many VPNs among our top picks that could be used for downloading torrents, but our preferred choice is Private Internet Access. This no-frills VPN has an absolute ton of servers, good speeds, and a nice amount of country locations to remain relatively anonymous. (Read our full review.) The price is right at less than $40 a year, and its privacy policies have been tested in court. Plus, advanced users can adjust their level of encryption for data encryption, data authentication, and handshake.
Norton WiFi Privacy performed very well in our latest round of speed tests. In the UK, we got FTP and HTTP download speeds of around 9.5MB/s (76Mb/s). Using endpoints in the Netherlands, that HTTP speed went up to 10.1MB/s (81Mbit/s). U.S. speeds were also very good, exceeding our non-VPN reference download at 5.8MB/s (46.4Mbit/s) for FTP and 4.8MB/s (38.4Mbit/s) for HTTP downloads.
Finding the best free VPN is an exercise in balancing those restrictions. TunnelBear, for example, lets you use any server on its network but limits you to 500MB-1GB per month. Avira Phantom VPN lets you use as many devices as you like and any server you like, but also restricts you to 500MB per month. AnchorFree Hotspot Shield also places no limits on the number of devices, but restricts you to 500MB per day and only US-based servers. Kaspersky Secure Connection also doesn't limit your devices but doesn't let you choose a VPN server—the app does it automatically.
At $7.50/month and $58.49 for a year, they're obviously trying to move you towards their yearly program. We awarded the company points for Bitcoin support, and their money-back guarantee. We're a little disappointed that they only allow a 7-day trial, rather than a full 30-days. The company is generous, with five simultaneous connections. They also picked up points for their connection kill switch feature, a must for anyone serious about remaining anonymous while surfing.
