Let's keep things very simple.VPN protocols are named for the technologies that VPN Provider use to ensure a secure and fast connection between you and the VPN server. Protocols have different specifications depending on the desired results. So, some VPN protocols' priority is data output speed and others' priority is on masking or encrypting data for the users' privacy and secure browsing.

How VPN uses Protocol

The VPN provider can use Protocols in two ways for its proper working.
1. They can use only one protocol that can do both functions. The function of data transfer and data security.
2. They can also use two protocols. One for the transfer of data and the other for the security of data.

Types of Protocol.


PPTP- point-to-point is the oldest protocol that was built in the 1990s by Microsoft for the usage of Dial connection. With the passage of time, it became easier to crack the encryption. There are many tools being used to crack the encryption which means that your data can be at risk with this protocol. This can be useful for users that don't have concerns with data security. As it can provide a good speed for data transfer.


L2TP is abbreviated as Layer 2 tunnel protocol. This protocol when used alone does not provide any security as it doesn’t encrypt any data. However, it is commonly paired with the security protocol IPsec. When paired with IPsec it becomes a very useful protocol for security with good speed. It is being widely used but can be easily blocked due to the reliance of UDP on a single port.


The open word might look suspicious to you in terms of security but this protocol is one of the strongest protocols for security. Because it has the strongest encryption. On the other hand, it provides a slower speed. This protocol has gained popularity due to its use of (virtually unbreakable) AES-256 bit key encryption with 2048-bit RSA authentication and a 160-bit SHA1 hash algorithm.


Secure socket tunneling protocol  provides good security and is difficult to block and detect, SSTP utilizes 2048-bit SSL/TLS certificates for authentication and 256-bit SSL keys for encryption


Internet Key Exchange version 2 is a common VPN tunneling protocol with a fast data speed and network switching capabilities. Similar to L2TP IKEv2 is usually paired with IPsec for encryption of data. This protocol is very good at re-establishing the link after a temporary connection loss.

There have been some protocols and many to come. The encryption of the data will keep getting stronger and VPN will keep helping the users to browse privately and securely. The StarkVPN is one of the VPN that keeps changing and adding new features to entertain and protect the users.
