In today's digital world, internet privacy and security are more critical than ever. Securing our online activities and sensitive information is critical with the growing number of cyber-attacks and data breaches. A Virtual Private Network (VPN) is one method for accomplishing this since it establishes an encrypted tunnel between your device and the internet, making it harder for anybody to intercept your data.
Nevertheless, not all VPN protocols are equal, and deciding on the best one may be difficult. In this blog article, we'll go through the finest VPN protocols available today and help you decide which one is ideal for you, depending on your needs and preferences.
What is a VPN protocol?
A VPN protocol is a set of rules and processes that control the transmission and encryption of data between a VPN client and a VPN server. The VPN protocol governs how the VPN client and server interact with one another and the amount of protection provided to data transfers.
A VPN protocol's principal function is establishing a secure and encrypted connection between a user's device and the internet. When users join a VPN, all their traffic is routed through the VPN server, and their IP address is changed to one assigned by the VPN server. This method needs to be revised to track the user's internet activity or locate them.
To maintain the security of data transfers, different VPN protocols employ varying levels of encryption, authentication, and data integrity. Some protocols favour security over speed, whereas others value speed over security. As a result, selecting the best VPN protocol depends on the user's demands and priorities.

MPPE encryption, on the other hand, is quicker than AES encryption and may be acceptable for low-security applications since it is less computationally costly.
L2TP/IPSec encryption type
L2TP/IPSec employs AES encryption and the IPSec protocol suite. This combination provides robust security and defence against numerous forms of cyber threats. Nevertheless, IPSec, like AES encryption, is computationally costly and may cause the VPN connection to slow down, especially on older or less capable computers.
SSTP encryption type
SSTP uses SSL/TLS encryption, considered highly secure and widely used to secure web transactions. SSL/TLS encryption is fast and efficient, making SSTP a good choice for users prioritising speed and security. However, SSTP is only compatible with Windows devices, so it may not be suitable for users requiring cross-platform compatibility.
IKEv2 encryption type
IKEv2 employs AES encryption and IPSec protocols comparable to L2TP/IPSec. IKEv2 is, on the other hand, designed to be more efficient than previous VPN protocols and can rapidly reconnect when the VPN connection is lost. Because of this functionality, it is suitable for mobile devices.
The encryption mechanism utilized by various VPN protocols has an impact on both the security and the performance of the VPN connection. The safest encryption is AES. However, it may slow the connection, whereas MPPE encryption is quicker but less secure. L2TP/IPSec and IKEv2 provide excellent security and efficient performance by combining AES encryption with IPSec protocols. Lastly, SSTP employs SSL/TLS encryption, which is safe and efficient but only supports Windows devices.
