Virtual Private Network VPN

A virtual private network, usually shortened to VPN, is a private tunnel through a public connection. Your phone talks to a server you trust first, and everything you do travels inside that tunnel. Anyone watching the network you are sitting on sees traffic going past, but cannot read what is inside it.

This matters because of where staff actually work. A sales manager answers email on the airport wifi. An engineer opens a job sheet from a hotel room. A café network is shared with everyone in the room, and building a fake network that carries the café name takes five minutes and cheap equipment. On an open network like that, anything sent without protection can be read by a stranger two tables away.

Here is what a VPN actually hides. It hides the content of what you send from the network around you, and it hides which sites you visit from the wifi owner and the internet provider. It also makes your device look as if it is sitting in the office. That is often the real reason a company buys one, and when Linkysoft is asked for a VPN it is usually because the accounting system only opens to office addresses.

Now the part that gets left out of the sales talk. A VPN does not make a weak password strong. If the password is the shop name and the year, the thief who has it walks in through the front door and the tunnel carries him politely. It does not stop someone typing their details into a fake login page. It does not clean a phone that already has bad software on it. And the company running the tunnel can see your traffic, so a free service is worth exactly what you paid for it.

For a business the setup is small. Buy a company account rather than personal ones, so you can switch a leaver off from a single screen. Turn it on automatically the moment a phone joins a network it does not know. And check the speed, because a slow tunnel is the reason staff quietly switch it off. Linkysoft pairs it with real login protection during a security review, since the tunnel protects the road and not the house. When we build a web application, we assume the connection cannot be trusted anyway and protect the data inside the system itself.
