If you're considering a hardware VPN, ask vendors whether their solution has a dedicated processor for encryption. Some of the newer VPN appliances use dedicated application-specific integrated circuits (ASICs) to handle the encryption algorithms, which make encryption much faster, especially on busy networks. Also make sure that the box you purchase will handle the number of tunnels and the throughput that you need now and in the future. You don't want to have to replace the box in a year or two.

We tested NordVPN and found that it works well with Netflix and other streaming services that block most other VPNs. It is compatible with all devices, does not retain logs, and offers a 30-day money-back guarantee (it's real, we checked). With a price so low, it's no wonder NordVPN is the most popular VPN out there, used by technology experts all around the world.
The servers of the company are numbered around 2000, which might be less than other VPN services. However, the spread is wider as it provides more than 148 cities and over 94 countries to choose from. The company allows for up to three devices to use its service. As with NordVPN, this company also keeps the exact numbers and other details around its operations rather vague.
PPTP. A consortium of vendors, including U.S. Robotics, Ascend Communications (now part of Lucent Technologies), 3Com, and Microsoft, developed PPTP. VPN software implementations are more likely than hardware implementations to use PPTP, although some VPN hardware vendors (e.g., Lucent in its MAX and Pipeline communication products and Nortel in its Contivity products) use it. PPTP software implementations can't handle high volumes of traffic, but PPTP hardware implementations can. PPTP 1.2 had major flaws, but version 2.0 fixed most of the problems. However, even this version 2.0 as Microsoft has implemented it is weak cryptographically because it still relies on the user's password to generate keys. In addition, PPTP's design and heavy promotion by a few large vendors such as Microsoft have made it suspect in some quarters.
Kaspersky Secure Connection is one of the fastest VPNs we’ve tested to date. We recorded UK speeds of 12.13MB/s (97.04Mb/s) via FTP and 10.27MB/s (82.16 Mb/s) via HTTP and 10.5MB/s (84Mb/s) and 9.39MB/s (75.12Mb/s) respectively for FTP and HTTP. The US VPN connection was so fast that we repeatedly re-tested it in case of errors or anomalies, because it more than tripled our non-VPN’d connection speed with 9.57MB/s (76.56Mb/s) downloads over both FTP and HTTP.

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.
Their best plan is 1-year subscription plan: $6.99 ($83.88). While their monthly price of $11.95 is at the high end of the spectrum (and they did lose a few points for that), their yearly price of $83.88 is lower than most our contenders. And yes, they also have a full 30-day refund policy. NordVPN also offers a dedicated IP option, for those looking for a different level of VPN connection. They do offer $2.99/month (75% discount) for a 3-year plan .
