An Introduction to Virtual Private Network (VPN)

I remember when I was in Dubai to visit some of my digital marketing clients for project discussions, I suddenly lost my data connection and tried to connect to a public WiFi. But, is it safe to connect such open networks? I asked myself!

I used Express VPN to ensure my connection is private and encrypted for secure browsing. Then I realized that using a VPN is not just a must-have for secure and safe browsing, but a security defence from bad guys (hackers) as well, especially when you are on the go.

As we are living in a hyper-connected world where everyone is facing privacy concerns, I thought to help Nogentech audience understand what a VPN (Virtual Private Network) is, its types and how a reliable VPN can protect you online. Whether you are working remotely, streaming your favorite TV show or just scrolling the web for information, using a VPN can enhance your experience and protection as well.

Let’s understand how!

A VPN (Virtual Private Network) is a service that establishes a secure, encrypted connection between your device and the internet. If you want some more privacy, security, and especially anonymity over the internet, then a VPN can provide you with that. 

According to many technical experts, a VPN can save you from various cyber threats, most notably from data and identity theft. You can use a VPN to secure your network so that no hackers can infringe on it. Several Google Chrome VPN extensions are also available that can be used to establish a secure connection between your device and the network.

• The VPN market is projected to reach $77 billion by 2026
• Over one-third of global internet users now rely on VPNs regularly
• Around 75% of VPN users access VPNs on desktops/laptops, while 66% use on smartphones
• In the U.S., 40% use free VPNs, while 51% opt for paid services

1. SSL VPN

It is a virtual private network (VPN) that is created using the Secure Sockets Layer (SSL) protocol so that the user gets a secure and encrypted connection over a less-secure network. SSL VPN is highly used in the corporate world to provide a secure and safe network to their employees. 

2. Client-to-Server VPN

In a Client-to-Server VPN connection, clients from the internet can connect easily to the service to access the corporate network or LAN. It is somewhat like you are using an extension cable on your home computer with the company. The public majorly uses a Client-to-Server VPN.

3. Site-to-site VPN

The connection between two or more networks, for example, the branch office network and a corporate network, is generally known as site-to-site VPN. Currently, various organizations utilize Site-to-Site VPN to gain control of the internet, enabling them to establish a secure connection for private traffic.

A reliable VPN:

• Encrypts your internet traffic: This means your data is scrambled so others can’t read it.
• Masks your IP address: It hides your real location by routing your traffic through a remote server.
• Secures public Wi-Fi use: Protects your data when you’re on open networks like in cafes or airports.
• Bypasses geo-restrictions: Lets you access content that may be blocked in your region (like streaming services).
• Prevents tracking: Makes it harder for websites, ISPs, and hackers to monitor your online activity.

I hope everything is now clear to every Nogentech reader.

No matter I was meeting clients in Dubai or working from a cafe using a public network, one thing remains constant: I never connected to the internet without Express VPN. Public networks look nice to connect (because they are free LOL!), but they’re open doors for cyber threats.

A reliable VPN is your digital bodyguard offering the freedom to work, stream, or explore online — without the fear of being watched. If you’re often on the move like me, make VPN security your travel partner.
