The more you care about your online privacy and protection, the better you understand how technology can influence your life, work, and future. Knowing how a VPN works and why you need to use one for your security can make all the difference in having a private digital space where you are not tracked or monitored. Now we will talk about VPN protection and everything you need to know in this area.

How does VPN work and protect us?

How a VPN works:

• When you connect to a VPN, your data enters a secure "tunnel." Instead of sending data directly to your Internet Service Provider (ISP), the VPN sends the data through a secure path.
• Any data transmitted through the tunnel is encrypted. VPNs use algorithms to transform data into random strings of letters and numbers (AES-256 and AES-128 are the most common). No one can access this data without a decryption key.
• The VPN provider decrypts your signal and sends it to its destination. Web servers see the connection as coming from the VPN server, not your device.
• When you receive data from the internet, the process is reversed. Any data sent to you passes through the VPN's encrypted tunnel, ensuring secure two-way communication.
• Your browsing history is deleted after you end your session. Many VPNs have privacy policies that include deleting browsing history and refusing to store logs of users' online activities. Logless VPNs help keep users anonymous.
• Some VPNs offer security features like a "kill switch" that disables your internet connection if the VPN stops working, preventing you from losing protection without realizing it.

What does a VPN hide?

Let's note right away that a VPN doesn't just provide security and privacy protection features. A VPN app also helps you bypass any location-based restrictions. For example, you can use a VPN for Android TV to watch sports or Netflix content that isn't available in your region. True, only a good provider like VeePN, is capable of this. Attempting to unblock a streaming service through a provider with insufficient security measures will result in denial of service or further restriction of content.

IP adress

Using a VPN instantly improves your digital privacy by hiding your IP address. When you connect to a VPN server, it assigns a new IP address to your device – one that your ISP doesn’t have. Your online activity is now tied to the VPN’s IP address, making it impossible to trace your actions back to you or your digital profile.

Your digital profile is a collection of information about you and your online activities. This profile can be accessed by multiple platforms and services, making it vulnerable to privacy and security risks. While companies use this information for targeted marketing, it also opens the door to cyberattacks. A VPN hides your real IP address, protecting your digital profile and making your online experience more secure and private.

Area of ​​occurrence

“Why do I need a VPN?” To hide your location, of course. Your IP address can reveal your location, but not with precision. Typically, it only shows the city or location where the internet servers you’re connected to are located. However, in addition to your IP, there are other ways third parties can track you.

Many apps, for example, use your device’s physical GPS location. Sometimes, access to your smartphone’s GPS is a condition of using certain apps. As a result, these apps track you everywhere you go.

But if you turn off GPS tracking and use a VPN, they won’t be able to track you, even on public Wi-Fi hotspots. Google can do this by triangulating the location of Android users connected to the hotspot. iOS devices, on the other hand, have a different approach to location tracking.

Navigation activity

Using a VPN also hides your browsing activity from your internet service provider (ISP). Many people don’t realize this, but your ISP has access to a huge amount of information about you — including your browsing and search history.

Did you know that your ISP can see your activity even in private browsing mode? Well, while incognito mode doesn’t store your search history, cookies, or other local data on your device, it doesn’t hide anything from your ISP.

That’s where a VPN can help. Connecting to a VPN means that your search requests go through the VPN’s server instead of your ISP’s. This means your ISP can no longer see what you do online — including what you type into your browser.

In addition to using a VPN, consider a reliable cookie cleaner to increase your online privacy.

Personal data

Places like airports, cafes, and hotels where you can enjoy free Wi-Fi are also goldmines for hackers and cybercriminals.

The best advice is to avoid unsecured public networks or Wi-Fi hotspots unless you are using a VPN. Without protection, anyone with low moral standards and some technical knowledge can steal your logins, passwords, or other sensitive information you are sharing.

A VPN ensures that your privacy remains intact by encrypting all data before it leaves your device. This makes your personal information unreadable to any malicious observer. I recommend always using a VPN app while traveling so that you don’t have to worry about connecting to public hotspots when you need to.

Conclusion

VPN is your guardian, which helps prevent data leaks or external surveillance on you. All this is possible thanks to encryption and redirection of the information flow. No one except the destination server can see it in its original form and therefore cannot falsify, analyze or detoxify the data.
