How Do VPNs Work, And Why Even Get One

VPN in computing stands for a virtual private network. By virtual, it means that it is not real. There are many dangers for online users, including scammers, hackers, and governments and corporations trying to use your private information. It is safe to say that online users are not safe. They are looking for opportunities to improve their safety and security. Internet users want their privacy. So, they are always looking for a secure network. Private networks are secure. However, it is not possible to keep an entire private network that others cannot use. A virtual private network creates an opportunity for the many users who desire privacy.

How Do They Work?

In the simplest way, a VPN is an arrangement for the user to use the owner's computer for his or her online activities. You can also use the concept to access your work computer at home or vice versa. Essentially, you will be using your computer to navigate another computer. So, the person on the other side on the internet, you are accessing cannot see your device.

Security in an online place relies on encryption. This is a process where information is hidden behind a password. Since someone can access the information online, encryption makes sure that the data is unreadable. So, if you want someone to access the information, you provide a key. When you input your key, the information is decrypted, and it becomes readable again.  

Every time you go online, your private information is visible, such as IP addresses, websites you are visiting, and such things. If someone wants to harm you, he or she can use that information to target you. Some people will target you for commercial interests such as selling to you, but others, such as governments want to snoop on you or control what you can consume online.

What Are The Benefits Of Having One?

Prevent Snooping

If you are using public Wi-Fi hotspots, you are vulnerable, as many snoopers will try to steal private information from your browser. Using a VPN keeps them away because they cannot access your device. Instead, they will access the server that you are using. If you are downloading material from piracy sites such as torrents, a VPN will keep all those who want to log you at bay. According to, it allows VPN users to download movies or TV shows from torrents and other streaming sites. Some countries prevent torrents and such piracy sites because of copyright protection. You can overcome that problem with a VPN.

Hide Your Location

Assume you are in China, and the government doesn't want you to access Twitter. A VPN can help you access and use twitter by ensuring that the information you send through the VPN remains in the VPN and does not get into your computer. So, the VPN provider, preferably stationed somewhere twitter is legal, will provide a secure platform hosted under them. You will be able to log on as if you are in the new jurisdiction.

Even companies are hiding their locations. For example, a company can have a business website hosted overseas because local laws do not allow it to operate the site in the host country. Gambling companies and other companies use this method. Even legitimate businesses choose a VPN to launch international offices.

Access To Cheaper Options

You can, therefore, circumvent almost any restriction online using a VPN. You can bypass geographic restrictions. You can access streaming services or prices that you are restricted to. For example, if you log in to buy airfare tickets in America, the price is in dollars and may have the same amount as someone in Europe, who pays for the same amount but in euros. A VPN in Canada will allow you to access iTunes for 9.99 CAD, which is just USD 7.3. You can defeat price discrimination and market segmentation using a VPN. 

Is VPN secure?

Different providers use different security protocols to hide your data. In the process, they achieve different levels of encryption. If you are trying to circumvent licensing and access rights, it is mostly secure. However, if you are trying to fool large organizations such as governments, they will most likely know you are using a VPN. The level of encryption determines how secure the VPN will be. Robust encryption methods are expensive, which makes good VPN service providers a bit pricey.

A virtual private network allows you to be where you want to be in the world. It enables you to access all those things that are geographically-restricted. If you're going to stay anonymous while surfing, a VPN will also make that possible for you. A VPN technically locks out everyone you want to access any information about you out.
