A good VPN provider cares about its customers and can offer a free trial version for the user to test and decide on a choice. Moreover, some VPNs will please you with a money back guarantee. If within 30 days of using the VPN, it does not suit you or does not satisfy your needs, you can take advantage of the return guarantee and be sure that you will get your money back.

Tunneling protocols can operate in a point-to-point network topology that would theoretically not be considered as a VPN, because a VPN by definition is expected to support arbitrary and changing sets of network nodes. But since most router implementations support a software-defined tunnel interface, customer-provisioned VPNs often are simply defined tunnels running conventional routing protocols.
A proxy server is another way to conceal your real location. By transferring data through a proxy server the data appears to be going to that server, not you - so for example if you’re in the US and the proxy is in Switzerland, the website or service will think it’s talking to a machine in Switzerland. The main difference is that VPNs protect all your traffic while proxies tend to be limited to specific types of data, such as peer to peer networking or web browsing. 
With a presence in 148 locations across 94 countries, you also won’t need to worry about international travel. Furthermore, the more than 2,000 servers are all well placed throughout common travel destinations and urban centers. Any package will land you unlimited bandwidth and speed, a guaranteed 99.9 percent uptime, and 24-hour customer service. With so many guaranteed features, it’s no wonder this vendor is considered among the best — although note that ExpressVPN only supports up to three simultaneous connections, which is the least of the services on our list.
Each internet request usually results in a whole series of communication events between multiple points. The way a VPN works is by encrypting those packets at the originating point, often hiding not only the data, but also the information about your originating IP address. The VPN software on your end then sends those packets to VPN server at some destination point, decrypting that information.
Generally speaking, transfer speed tests via NordVPN’s UK endpoints continue to impress, with FTP downloads clocking 10.4MB/s (83Mbit/s) and HTTP downloads at 10MB/s (80Mbit/s). However, we saw unusually slow FTP results from our Dutch reference server, at an anomalous 5.1MB/s (40.8Mbit/s), compared to an HTTP download at 9.9MB/s (79.2Mbit/s). That said, U.S. speeds have improved on previous tests, coming in at around 3.5MB/s (28Mbit/s) for both FTP and HTTP transfers.
In conjunction with information security experts at The New York Times (parent company of Wirecutter), we reached out to our finalists with questions about their internal security practices. We asked how they handled internal security access, how they communicated securely with customers, in what ways they collected reports on security bugs, and of course whether their statements on logging policies matched their marketing and privacy policies. We also considered which companies had public-facing leadership or ownership, and which ones openly supported projects and organizations that promoted Internet security and privacy. (For a full breakdown of trust and VPNs, check out the section above.)
Tunnel endpoints must be authenticated before secure VPN tunnels can be established. User-created remote-access VPNs may use passwords, biometrics, two-factor authentication or other cryptographic methods. Network-to-network tunnels often use passwords or digital certificates. They permanently store the key to allow the tunnel to establish automatically, without intervention from the administrator.

ExpressVPN operates servers in 78 countries, 20 of them in APAC alone. Torrenting is allowed on all servers. It’s consistently performed well in our unblocking tests and our speed tests so is a good option for streaming. It can unblock both the US and Australian Netflix catalogs in a browser as well as in the Netflix app. It keeps no traffic logs and is based in the British Virgin Islands, where it is not subject to any data retention laws. ExpressVPN makes apps for Windows, MacOS, Android, iOS, Linux (command line) and some wifi routers.

Natively on your operating system with the built-in VPN functionality (no apps required). Many operating systems natively support VPNs: Windows, Mac OS, Android, and iOS. To use this you will need to import your VPN’s configuration files onto your device. This will use the IPSec/IKEv2 or IPSec/L2TP protocols, rather than OpenVPN, since OpenVPN can only be used through apps. (PPTP is also sometimes supported, but this VPN protocol is not recommended due to security vulnerabilities.)
Cost: You have three pricing options depending on how often you want to pay. The cheapest IPVanish plan is to buy a full year at once for $77.99, making the monthly rate $6.49/month. If you pay for three months at once for $26.99, the monthly cost comes down to $8.99/month. However, to subscribe on a monthly basis with no commitment, it will cost $10/month.
Not all VPN services require that you pay. There are, in fact, many excellent free VPNs. But all of the free VPNs we've tested have some kind of limitation. Some limit you to just a few simultaneous connections or devices on an account. Others restrict you to a few hundred MBs of data per day or per month. Others limit you to just a handful of servers. Still others do all of the above.
They even offer the most generous simultaneous connection count, with six simultaneous connections through their network, where everyone else offers five or fewer. NordVPN's network isn't as large as some of their competitors, so if you're trying to obfuscate your tracks, you might want a company with more servers. Otherwise, this company is clearly providing a winning offering.
