Virtual Private Networks (VPNs) provide a secure connection between a private network and a public network, providing public network users to transmit and receive information as if they were connected directly to the private network.

VPNs have proved to be a successful alternative for individuals wanting greater anonymity in their daily Internet surfing, but their use in the corporate sector has skyrocketed in the past few years. This is particularly true since March 2020, when VPN usage increased by 41% in a month, as per industry data.

As our scattered workforce expanded at an increasing rate throughout that period, the demand for highly secure accessibility, apps, and services grew increasingly essential.

What are VPN Protocols?

VPN protocols specify how information is routed over a network. These protocols vary in their parameters depending on the advantages and intended situations; for instance, some VPN protocols prioritize bandwidth utilization speed while others concentrate on disguising or encrypting data packets for confidentiality.

Top 5 Types of VPN Protocols in Business Sectors

When it comes to VPN functioning, there are two major approaches:

1) two protocols are utilized (one to send data through the tunnel and another to protect that traffic).

2) a single protocol is used for both data transmission and data security.

Here are five popular VPN protocols and their associated main advantages.

1) SSL

SSL, or Secure Socket Layer, is a VPNs protocol that encrypts an HTTP request. Various apps, like chat messengers and websites, are guided to provide a secure connection between the browser and the webserver. And HTTPS secures the connection between an application server and a web browser.

SSL operates with data verification via a vital mutual creation of public keys that are used for both decoding and encoding the request contents. When the browser sends the request in its raw form, it encrypts it. Similarly, decryption occurs when the application is going to be accepted by the server.

2) PPTP

Because of its simple encryption and light security, PPTP provides a considerably quicker connection. It works on most systems and is simple to set up. However, it is not suggested unless security is entirely unnecessary.

3) OpenVPN TCP

It is expansive and released under the General Public Licence, allowing the community to alter or see the source code in order to identify and address any faults.

This classification depends on the TCP protocol, which was merged with the Internet Protocol (IP), resulting in a set of recommendations for how devices communicate data back and forward on.

In other terms, TCP is a connection-oriented protocol. Furthermore, it builds and maintains this link as apps exchange data. The transmission control protocol is most commonly used on the internet.

Before the next packet is delivered, confirmation of the packet's arrival is required for each piece of data communicated. If no verification is achieved, the current data is transmitted again.

4) OpenVPN UDP

UDP, or User Datagram Protocol, is also another communication protocol used to communicate or convey data between users and the internet. Unlike OpenVPN TCP, OpenVPN UDP is designed for low data transmission at the expense of dependability.

In this scenario, UDP just transfers the data without any confirmation or verification. As a result, it requires fewer upkeeps and has a shorter latency. These characteristics make OpenVPN UDP suitable for video and audio broadcasting, as well as gameplay.

5) IPSEC

This VPN protocol is primarily used to shield Network protocols from attacks over an IP network. Internet Protocol Security protects IP communication by inspecting, verifying, and concealing each sensed data while linking.

This VPN protocol operates in two modes: tunneling and transport. Encrypting messages in the data packet is how the transport mode operates. The tunneling mode, on the other hand, converts the whole data packet into a code. Internet Protocol Security may be used in conjunction with other protocols to improve and expand the security system.
