Thanks to YouTube ads, almost everyone today thinks a VPN is a tool to “hide” on the internet, skip ads or watch foreign videos. But that is only a marginal and often exaggerated use. The original and main purpose of a VPN is quite different and far more practical. Let us clear it up.

What a VPN really is

VPN stands for Virtual Private Network. In simple terms, it creates an encrypted “tunnel” between your device and some remote network. Through this tunnel you reach that network as if you were connected directly inside it, even though you are physically somewhere else.

The key words are private network. A VPN is not primarily about hiding from the world, but about securely connecting to a specific network that you otherwise cannot reach from outside.

What a VPN is really for

This is the real reason VPNs were created and where they make the most sense:

  • Working from home or on the road. An employee securely connects via VPN to the company network and works with files, systems and printers as if sitting in the office.
  • Access to devices at home. You can reach a home server (NAS), cameras or other devices remotely and securely, without leaving them exposed on the internet.
  • Linking branches. Two company sites can be joined into one shared network over a VPN.
  • Secure access to internal systems. Accounting, a database or an internal app need not be exposed to the public internet; only a verified person reaches them over the VPN.

Why it is safer

This is important. If you exposed a company system or cameras directly to the internet, attackers would find them within minutes (automated scanners search for open services non-stop). A VPN prevents this: the services stay hidden in the private network and only someone who authenticates gets in through the encrypted tunnel. That is why for cameras and remote access we recommend a VPN instead of port forwarding, as we also describe in the article on camera systems.

And what about the “hiding” VPNs from the ads?

Commercial VPN services (the ones from the ads) work a little differently: they route your internet traffic through their server, so you appear to be in another country. This has legitimate uses, for example on public Wi-Fi or with geoblocking. But it is worth realising what a VPN does not do:

  • It does not make you invisible or anonymous. It merely shifts trust from your internet provider to the company running the VPN.
  • It does not protect against phishing, viruses, or giving away your password yourself. Other things handle that, which we cover in the article on antivirus.
  • For ordinary browsing over encrypted HTTPS, most people do not need a commercial VPN at all.

In short, a VPN is not a magic cloak of invisibility. It is a secure bridge into a specific network.
