Virtual private network is an invaluable solution to the current common problems-protecting your anonymity and security while surfing the Internet. Among millions of VPN users, the most curious people are not only keen to obtain a VPN, but also understand the complex structure of the VPN in more detail.

VPN protocol basics

If you don’t have a clue, the easiest way to get a VPN protocol is the bread and butter of each VPN service. They are a backbone composed of transmission protocols and encryption standards, allowing you to quickly and securely travel to and from the VPN server. There are five main types of VPN protocols: OpenVPN, PPTP, L2TP/IPSEC, IKEV2 and SSTP. In some cases, the agreement may be better than other agreements. The following is a brief summary:

OpenVPN should be your preferred protocol. This is the most comprehensive choice, achieving a perfect balance between speed, security and reliability-in fact, most VPN services use OpenVPN.

IKEV2 performs well on mobile devices because it can automatically reconnect to prevent you from losing connection with the network. Speed ??is a big advantage of this agreement, but the cost is the limited platform and the installation process is difficult.

If you cannot use OpenVPN for some reason, L2TP/IPSec is a good choice. L2TP/IPSec is a typical one that knows everything and nothing is professional, so it is a good choice for non-major use.

If you use Windows, SSTP is the only VPN protocol you need. As part of the operating system, it is fully integrated, easy to use-and enjoy Microsoft's support. However, setting up the SSTP protocol on other platforms is not impossible, but very difficult. In fact, Microsoft's patented technology may also be a concern for some people.

PPTP-Unless absolutely necessary, try not to use this protocol. This is the oldest agreement, which has become obsolete over time. Although it is fast, it is actually not safe. If you are concerned about your privacy, please avoid using this VPN protocol.
