Virtual Private Network (VPN) is no longer seen as a luxury or a secret tool. It’s widely used among internet users. One of the common reasons for its increased global usage is because it helps bypass regional censorship and helps to access geo-blocked websites and services.
Also, the recent 2018 Statista report shows 26% of internet users use a VPN or proxy server. Among the regions, Asia Pacific ranks first.
Here, we will explore what tunneling is in regard to VPNs and how it extends its private network services across the internet to make a user safe and anonymous while browsing the Internet.
What Is VPN Tunnelling?
Here, the process of data encryption and data encapsulation works like a tunnel between your device and the destination server of the VPN you are connected to.
Hence, this VPN tunneling concept encapsulates and offers encryption as another layer to the data. So it can be carried safely through the non-secure internet.
In other words, a VPN tunnel is a combination of encryption and encapsulation that works as a secure tunnel between the user’s device and the Internet. All the data sent by the user travels through this tunnel. Here, the protected data includes all your browsing history, chatting and other internet traffic from all the sources who can trace you. For instance, the government, ISP (internet service provider) and anyone who tries to monitor your activity.
Even if dangerous gangsters and skilled criminals get to know about the transfer of money, they can’t do anything about it. Here, two levels are offered – encapsulation disguises the vehicle in which the cash is kept in such a way that no one can recognize it. Encryption ensures that even if someone recognizes the vehicle, they can’t reach it.
Does a VPN Tunnel Keep the Data Encrypted Until It Reaches its Destination?
However, the level of encryption provided by the VPN tunnel depends on the tunneling protocol used for encapsulating and encrypting the data. Many VPN tunneling protocols are offered. Some commonly used protocols in the VPN industry are PPTP, IPSec, OpenVPN, SSTP, IKEv2, and L2TP.
Common Things Users Must Be Aware of VPN Tunnelling Protocols
- What’s the speed?
- Is it secured?
- Does it bypass censorship easily?
- How easy it’s to access and use it?
Which VPN Tunnelling Protocols to Use and Which to Avoid?
On the other hand, L2TP/IPSec offers 256-bit encryption, but it’s slower and struggles with firewalls. The secured VPN tunneling protocol, SSTP is only available on Microsoft Windows. Lastly, PPTP is an insecure and outdated protocol that must be avoided.
Furthermore, VPN providers offer single or multi-protocols. Here, single protocol VPNs are generally the ones that offer only one type of protocol, mostly the OpenVPN protocol. And, multi-protocol VPN providers support a combination of more than one protocols, useful for both regular internet users and business organizations.
