How a VPN Tunnel Lets you Connect to all Networks with Confidence
A VPN tunnel is a notable buzzword in the VPN industry. Besides being a trendy phrase, it accurately presents the bottom line of VPNs. In short, the analogy reflects the virtual route between your device and the internet network. Commonly, a VPN tunnel has a reliable sidekick: encryption. It is the core element, gluing everything together nicely. With encryption up to the modern standards, a VPN service guarantees confidentiality and integrity for all your online affairs.
What is a VPN tunnel exactly?
Let’s briefly investigate the premise here before we go deeper into the encapsulation and encryption components of a VPN tunnel. A regular internet visitor sends thousands of requests daily. Without a VPN, all of your communications and data transmissions are easily obtainable by various parties.
For instance, let’s assume that you search for cheap furniture for your flat. Your ISP instantly knows about your intentions and,, can sell this data to marketers. In addition to your ISP keeping tabs on your browsing activity, third-parties might also intercept your connection. When marketers build profiles, they can adjust offers to specific users. For example, after searching for furniture, you might immediately notice sponsored posts and ads for such home goods on your social media accounts.
A VPN tunnel implements a tunneling protocol that encapsulates traffic. Imagine sending a package to your friend. You put in a box to protect it and to make sure that snoopy neighbors won’t learn its content. A VPN tunnel performs the same action, making sure that your package reaches the recipient uncompromised. However, tunneling is not enough. To provide maximum privacy, VPN providers encrypt (or scramble) web traffic into an unreadable format. As a result, all requests that travel through the VPN tunnel are worthless to your ISP and other nosy parties.
Serving encryption: how does it work?
It is obvious that a VPN tunnel would not be complete without encryption. There are athat VPN providers can apply, ranging from Point to Point Tunneling Protocol (PPTP), L2TP/IPSec, SSTP to OpenVPN. However, how does a VPN encryption work to secure your data while it travels through the network?
When data travels through a VPN tunnel, the delivery of requests is a dual process. The first stage focuses on the encryption of data that you sent to the server. The second step is decryption, or, in other words, conversion of the scrambled message into a format you can read. It occurs when the VPN server sends your request to the internet. Before the implemented request pops up on your device, the server encrypts data one more time. Then, finally, once the request has gone through the VPN tunnel, you receive the decrypted message. Your requests are nearly impossible to alter or obstruct during this process of encapsulation and multiple data conversions.
So, after understanding a bit more about the technical process of VPN tunneling and encryption, you might wonder why this procedure came to be. Let’s inspect the prevalent concerns that a VPN tunnel tackles as a relentless advocate for users’ rights to keep their digital identities private.
Why should you use a VPN tunnel for all communications?
Once you set up a VPN tunnel, it thwarts all the attempts to monitor or modify your requests. The continuous protection prevents advertisers, ISPs, search engines, government entities, or other websites from collecting and selling your data. Hence, once you are “inside the VPN tunnel”, all your browsing activities become private affairs that nobody can spy on.
Besides protecting you from snoopy entities, VPN services make you immune to some of theto compromise your digital presence. For instance, a VPN tunnel is a necessity whenever you are connecting to unsecured Wi-Fi networks. Crooks might monitor the established connections, but with the around-the-clock protection from a VPN, these malicious actors won’t be able to track your actions.
At first glance, it might seem that setting up a VPN tunnel requires technical skills and an in-depth understanding of encryption, encapsulation, etc. However, wrapping up your data transmissions in a safe, encrypted blanket is an intuitive process that can only take a minute. For example, after installing Atlas VPN and choosing a suitable server, you instantly get all the benefits of a VPN tunnel.
