In today's digital age, we spend more time online than ever. Privacy and security on the internet are increasingly important. VPN (Virtual Private Network) has become a key tool for protecting our data through safer connections and anonymous browsing. If you're wondering what a VPN is, how it works, or want to know what it's used for, read on for our complete guide.
VPN, or Virtual Private Network, is a technology that enables the creation of a secure and encrypted connection between your device and the internet. This means that all data you send and receive over this network is protected from unauthorised access and espionage. VPN works by routing your internet data through a VPN server which provides you with a new IP address, thereby hiding your real location and identity.
The internet has become an indispensable companion for modern life, and our need to use it safely has increased. We want to protect our personal data and maintain our privacy. This is where the concept of a Virtual Private Network (VPN) comes into play. Its goal was to create a secure and encrypted connection between the user and the internet.
Initially, VPNs were designed for businesses that needed to create secure remote access for their employees. They could connect to the company's private network from anywhere, and the private network ensured that confidential data remained protected. Today, employees often work outside the office (on public Wi-Fi networks, in cafes, at airports, on public transport), where they are exposed to a greater risk of sensitive data leakage. Therefore, it is important for them to secure remote connections.
VPNs have also become important for individuals, protecting them at home and when they're on public Wi-Fi.
VPN acts as a shield against potential risks by encrypting data transmitted between the user's device and the internet, thereby preventing unauthorised access and eavesdropping. Additionally, it allows users to mask their real IP address, making it more difficult for third parties to track their online activities.
VPN thus offers a solution to growing concerns regarding privacy, security, and online freedom. By creating an encrypted tunnel and hiding one's real identity, it provides individuals and organisations with the peace of mind they need for safe and anonymous navigation in the digital environment.
VPN offers you many advantages that can contribute to a safer online experience. To find out if you need an encrypted connection, let's go through the most important benefits that VPN networks offer.
The Most Well-Known Advantages of a VPN Connection
Although a virtual private network offers many advantages and is a useful tool for protecting privacy and security on the internet, there are also some things to consider. Before getting a VPN, it is important to be aware of:
VPN acts as an intermediary between your device (computer, smartphone, or tablet) and the internet. When you connect to a VPN, your internet data is encrypted by the VPN client and travels through a special encrypted tunnel to the VPN server. The VPN server decrypts the data and sends a request to the target server where the website is located. The data then travels back in the opposite direction in the same way. This creates a private and secure connection to the internet. Your real IP address remains hidden and you browse the internet with a new IP address provided by the VPN provider.
There are several different types of VPNs that can be used depending on your circumstances.
Some web browsers have their own integrated VPN function (for example, Opera or Firefox). Usually, you can find this function in the browser settings in the privacy and security settings section. After enabling VPN in the browser, an icon appears in the toolbar. When you click on the icon, a window pops up for connection and server selection.
Keep in mind that VPN extensions in browsers provide protection only for browser activity. If you want to secure the entire device and all traffic, it is recommended to use a separate VPN application or an integrated VPN throughout the operating system.
A number of integrated free VPN add-ons are often very limited. For example, they offer only a few servers, limit the maximum speed or the number of users connected to one server. With browser based VPNs, you usually find the option to switch to a paid version, which removes these limitations.
A few tips for proper use
Make sure your VPN is always updated to the latest version so you have access to the best features and security updates.
If you're having trouble connecting, try restarting the app or even the whole device. You can also try switching between VPN servers to see which one offers a faster connection.
Pay attention to warnings and alerts that may appear when you change the VPN status. Sometimes, some apps may be able to track your activity when you turn off the VPN.
How to use the VPN app on Windows, Android or iOS?
Once you have a VPN installed on your computer, phone, or other device, you will most commonly work with it by turning it on or off as needed. Let's go through how to do this.
When choosing a VPN, it is important to carefully select a reliable and high-quality service that meets your needs and provides real protection for your privacy. Here are the key parameters you should focus on:
Top criteria for choosing a Virtual Private Network
For a VPN to be effective, it must use the strongest available encryption methods (regardless of whether it is a paid or free service). Only then is your online security guaranteed.
