What Is VPN & Why Do We Need It?


With internet becoming an indispensable part of our life, online security and data privacy has snowballed into a major talking point across the globe. Hence today online protection and data theft are no more considered as a trivial or fringe issue. It has become a mainstream issue that is even shaping the political discourse in several developed countries. This heightened concern over online privacy has once again underscored the importance of VPN or Virtual Private Network.

Although VPN technology is almost as old as the internet itself, many are still not aware about the important role that this technology can play in securing our online data against theft and hackers. VPN technology is basically a security tunnel between your device (PC, smartphone, tablet etc.) and the internet network known as server. This security tunnel establishes an encrypted connection that stifles any attempt by hackers and snoopers to get any possible unauthorized access to your data.

VPN in many ways can be compared with your computer firewall. Just as firewall protects your P.C and laptop against unauthorized access by hackers, VPN performs the same critical function with regards to your online data.

Since the value of online data has increased phenomenally over the years, the demand for the best VPN services has not surprisingly skyrocketed. It has now almost become a necessity that can’t be compromised nor ignored.

Below we’ve shed light on why do we need a VPN and how it really makes our online lot more secure and safe.

Enjoy the internet without restriction: VPN gives you the gateway to overcome the cruel world of censorship and restriction by giving unhindered access to geo-blocked websites. However, netizens must bear the responsibility of not using these blocked websites for promoting any anti-social or anti-national activities. If popular trend is anything to go by then most people use VPN to unblock entertainment websites like Netflix & Hulu and not websites that promote unwanted social activities.

Types of VPN:

Although there are several types of VPN protocols, three most common and predominant protocols are as follows:

PPTP: PPTP is one of the oldest VPN protocols but today is rapidly losing popularity due to its unreliable security.

L2TP/IPsec: L2TP/IPsec offers more enhanced security features and is therefore generally considered comparatively safer than PPTP. It lays out two protocols wherein L2TP protocol is used to create a tunnel and IPsec provides a secure channel. Experts claim that this dual protocol paves way for comprehensive security measures.

Open VPN: OpenVPN is an SSL-based VPN protocol and is fast gaining popularity. Apart from cutting edge security, its increasing popularity is lot to with the fact it is a open source software and is freely available.
