The internet is becoming a part & parcel of our life. Whether you are a student or businessman, the internet has always been something for you. It is a useful source for promoting your business and for gaining knowledge. In short, it has brought the whole world to our fingertips.
However, it has to be kept in mind that every good thing comes with some flaws too. Cyber attacks are increasing day by day. Your information is not safe from even government authorities. Cybersecurity is gaining more importance as hackers are always trying to get you valuable data. Hence, VPN is the only thing that comes to our minds whenever we hear cybersecurity.

Types of VPN and VPN Protocol
Using the internet without a VPN may risk your valuable data. Usually, VPN stands for the virtual private network. It can hide your data and can encrypt your data. So, the hackers can not get your data easily. This is the reason why most people use a VPN.
The VPN is mainly of two types –
i) Remote Access VPN
ii) Site to Site VPN
i) Remote Access VPN: Remote Access VPN helps remote users to access the data present in the corporate data center. It creates a tunnel between remote users & the company’s network, even though the user may be in a public location.
ii) Site-to-Site VPN: Site-to-Site VPN is also known as a router-to-router VPN. Usually, large companies that have many different branch offices at different locations use this kind of VPN. It creates an imaginary bridge between networks that are located in two different locations. This VPN connects the networks through the internet and provides secure and private communication.

Types of VPN Protocol
A VPN uses some protocols. It determines how data will route between the user’s computer and the VPN server. Each VPN protocol differs from the others and offers different features and security measures. In this article, we are going to discuss 5 different VPN protocols. So, here we go:
IPSec or internet protocol security secures the internet traffic within an IP network. It provides some private/public keys to lock/unlock the data and thus enhance security. It mainly works in two modes -Transport mode and tunneling mode.
The transport mode encrypts the messages of a data packet whereas the tunneling mode encrypts the whole data packet. So, it provides total security to your information against any snooping eyes. Moreover, it will be quite difficult for anyone to understand the information users are sending and receiving.
However, it comes with some disadvantages too. The setup process for such a VPN is quite time-consuming. Moreover, IPSec VPN is expensive than other available VPNs.
Microsoft and Cisco together have developed L2TP. Layer 2 Tunneling Protocol is a VPN protocol that uses tunneling mode to secure your data.
L2TP can be combined with other VPN security protocols like IPSec to develop a more secure VPN protocol. In this type of VPN Protocol, the data travels between two L2TP connection points.

This VPN security protocol is widely used. It was first introduced in 1995 and integrated into Windows 95. However, it is also used in Linux and Max. PPTP or point-to-point tunneling protocols create a tunnel between connections to encapsulate the data.
It usually uses two processes to implement security. First, a tunnel is developed between two networks, and second, the data that flows through the tunnel is encrypted.
Open VPN is another popular VPN protocol. It is an open-source VPN protocol that uses AES-256 bit key encryption, with 2048 bit RSA authentication and a 160-bit SHAI hash algorithm.
Apart from this, it is available to many platforms like Windows, macOS, Linux, Android, iOS, and more. Since it is open-source anyone can integrate it into other projects as well as can scrutinize its source code for vulnerabilities.

Secure Shell is a cryptographic network protocol that creates a secure tunnel over the unsecured network.
It usually connects SSH client applications and SSH servers using a client-server architecture. The data transferred is encrypted. So, the protocol is quite helpful in securing your data.
I hope, you have liked the article and found it useful. Here we have only listed 5 useful protocols. A good VPN service that includes these protocols will offer numerous features. So, choose the VPN that fulfills your demands.
