VPNs or virtual private networks, to be more precise are a wonderful technology that is growing day by day. Each day developers are adding more security, reliability, and advancements in algorithms to make it a fine product for users.

A right virtual private network can be an excellent source of protection while surfing the internet using public Wi-Fi. it is because it can completely mask your IP address, making you anonymous to hackers and prying eyes.

However, there was a time when these networks were not so secure and advanced. In this article, we will take a quick look at how VPNs have changed over time and how things have progressed over the years.

So, if you are interested, keep on reading and explore the advancements in virtual private network technology.



How VPNs have changed over time

In the very early days of virtual private networks, things looked different. There was a lack of protocols and encryption which made it insecure to use them. But still, there were many people who used it for anonymous browsing and hiding their IP addresses from ISP.

Back in those days, an individual would need to download VPN software and then use the OpenVPN protocol to connect their machine with the remote server. But this method was not foolproof as you can never be sure if it would keep your data private at all times and also if the VPN company is trustworthy or not.

And things got worse when government agencies like NSA started collecting mass user information using a secret data-mining program called PRISM. There was a need to secure our internet connection, and this is when the real game started.

VPN protocols for better security

After NSA screwed up with PRISM, there was an outcry in the media about online privacy. People started looking for more advanced technologies to protect their identity on the web.

To resolve this issue, VPN companies started developing technologies and protocols to keep user data private. Some of the major advances in the field of virtual private networks are:

Stronger encryption

Even though SSL was used for encryption back then, it was not efficient enough to secure what we wanted online today. In response to hackers and surveillance agencies, VPN software developers started using AES-128, RSA 4096, and SHA512 that are still used today.

VPN client program for faster connection

Since the internet speed is dependent on server location, some companies created their own client software to connect with servers quickly. For example, some popular protocols like PPTP offer speedy connections by allowing users to establish a direct connection instead of hopping through multiple servers across the globe.

Combining network protocols for different purposes

A VPN protocol is not only meant to encrypt your data but also some are designed specifically to unblock geo-restricted websites and content. These protocols are Tunneling protocols like SSTP, OpenVPN, etc that allow users to access blocked content and maintain privacy.

IP address cloaking

Since an IP address is like your identity on the internet, there was a need to hide it, but this wasn’t an easy task earlier. Companies found their own ways of doing this by creating fake DNS requests etc, But now you can easily change your virtual location using multiple servers that are present in different parts of the world.

VPN software for mobile devices

Back then, many VPN companies offered dedicated desktop apps to access their private networks and connect with servers through encrypted tunnels. But now due to the increased use of smartphones and tablets by people, they have created separate apps for Android and iOS platforms as well.

Last Minute Thoughts

The need for advanced security protocols and encryption methods is still there, but we can see that VPN companies are working on this issue and making things more secure and efficient day by day.

So, if you want to get more proactive protection then make sure to use the latest technologies available in the field of virtual private networks. Hope you like this article. Do let us know what you think about it in the comments.
