It's nearly impossible to spend more than an hour on YouTube without encountering an ad or promotion for VPN services like NordVPN, ExpressVPN, or Surfshark. Companies offering such services often claim that VPNs are the ideal tool for safeguarding your privacy and security online, as well as for bypassing geo-blocks or censorship. Some even assure that it helps protect your data.

However, the truth is that VPNs are only useful in a limited number of cases. Think of a VPN as a tunnel between two points on the internet. It was originally designed to remotely connect employees to office networks or link multiple offices into a single network. Over time, it started being used for other purposes like bypassing restrictions or ensuring online safety. Many believe that using a VPN will help avoid being monitored while browsing the internet.

We’ll look into what exactly a VPN does and why using one may not always be safe or justified.

What is a VPN? A VPN, or virtual private network, allows you to remotely connect to private networks. For example, if you work from home, a VPN can provide access to your company’s network, enabling you to work as if you were in the office.

If you have multiple devices in your home, you’re using a local network— all connected to the same Wi-Fi or via cable. VPN works similarly, but through the internet.

The process of connecting to a VPN is straightforward. A company or an individual sets up a VPN server at their office, home, or a data center, and with the right credentials, you can connect to it using an app on your device. Modern operating systems like Windows, macOS, Android, and iOS already come with built-in VPN clients.

Do I Need to Use a VPN? There are several reasons why you might need a VPN. You could use it for working from home, bypassing internet censorship, or accessing content unavailable in your country.

A VPN can also be helpful if you want to access video services that are blocked in your region. For example, with a VPN, you can connect to a server in the US and watch shows that are only available to American users. However, sometimes a VPN server's bandwidth may not be sufficient to stream video in high quality.

Why You May Not Need a VPN Using a VPN has its downsides. For instance, your internet traffic could be restricted by company or VPN provider policies, and not all VPNs guarantee privacy. Moreover, free VPNs may track and sell your data to advertisers.

Will a VPN Make Me Anonymous Online? Although many people use VPNs to protect themselves from hackers in public Wi-Fi networks, most online services today use HTTPS and end-to-end encryption. Therefore, VPNs are not always necessary for security, especially if you're connecting through encrypted connections.

Conclusion A VPN is a useful tool for certain tasks like remote work or accessing geo-blocked content. However, you shouldn't blindly trust every VPN service, especially if their privacy policies are not transparent enough.
