The main goals of VPN technology is to be able to provide a high level of security over the internet. It makes use of an encryption system that is used to avoid any leak of information and it makes sure the data will only be viewed by the authorized recipient.

Security protocols are important in the VPN industry. Maximizing security over the internet lines/connections are their main purpose. Here, we’ll look at the most common VPN protocols that VPN companies use.

Internet Protocol Security (IPsec)

This term refers to the group of protocols which are transported over the internet lines to secure the data being transmitted or received. The most common IPsec protocols include Authentication Header (AH), Internet Key Exchange (IKE) and the Encapsulating Security Payload (ESP). When these protocols are combined, the flow of data between gateways, firewalls, hosts, servers and so on will be secured at all times.

Open VPN a.k.a. SSL VPN Protocol

This is actually a freeware used to create a site-to-site or point-to-point connection between servers and users. It makes use of an SSL/TLS security system that’s why it is called as such. Open VPN works like this. Users have the ability to grant permissions to the files being transmitted or shared incorporating the use of passwords, certificates and pre-shared keys. Only the corresponding parties know these passwords. Therefore making the connection as confidential as possible. This kind of protocol are usually used in some LAN games.

Point-to-Point Tunneling Protocol (PPTP)

Also known as the channel traffic between VPN protocols. Data are sent through “Tunnels” where the security levels are high. Encryption system is used in this type of protocol. Windows OS makes use of this protocol.

Secure Socket Tunneling Protocol (SSTP VPN)

This protocol is used to synchronize the communication between multiple endpoint. It also allows such simultaneous utilization of the system so that there will be an efficient use of network resources. This is considered to be one of the most flexible protocols since it supports roaming services. This means that users can access the VPN protocol anywhere and anytime they want to.

There are many other VPN protocols out there. Those mentioned above are just the commonly used ones. Like people, each protocol is also unique. Each has its own strength and it has its own weaknesses. But no matter what kind of protocols there are, they all provide users the maximum security they deserve.
