Short answer: they solve different problems. A VPN subscription app routes your internet traffic through a company’s servers, mainly for privacy or to change your apparent location. A home VPN connects you back to your own network so you can reach your files, PC, NAS and cameras securely from anywhere. Many people need the second, and think they are buying the first.
The word VPN covers two very different tools. Adverts for subscription VPNs are everywhere, so people assume that is what you need to “access your home network when you are away”. It is not. Understanding the difference saves money and avoids a false sense of security.
What a VPN subscription app does
You install an app, connect, and your traffic goes through a server run by the VPN company before reaching the internet. Websites see the server’s address, not yours. It can help you stay more private on public WiFi and watch services from another country. It does not connect you to your home.
What a home VPN does
A home VPN runs on your router, NAS or a small device at home. When you are away, your laptop or phone connects to it over an encrypted tunnel, and from then on behaves as if it were plugged into your home network. You can open files, use a printer, check cameras or reach a home PC. You can also route your internet through home, which is handy when you are abroad and need UK services.
Side-by-side comparison
| Feature | VPN subscription app | Home VPN |
|---|---|---|
| Main purpose | Privacy and changing location | Secure access to your home network |
| Where it connects | A company’s servers | Your own router or NAS |
| Reach home files and cameras | No | Yes |
| Monthly cost | Usually a subscription | Usually no ongoing fee |
| You control the data | You trust the provider | You run it yourself |
Which one do you need?
- Safer browsing on hotel or café WiFi: either works, and a home VPN keeps your traffic going through your own connection.
- Watching UK services abroad: a home VPN gives you a UK address, as long as you do not break a service’s terms.
- Reaching home files, a NAS, a PC or cameras: only a home VPN does this.
- Hiding your activity from your broadband provider: a subscription VPN, with the caveat that you now trust a different company.
How a home VPN is set up
- Enable a VPN server on a router or NAS that supports it, commonly WireGuard or OpenVPN.
- Create a key or certificate for each device, rather than sharing one password.
- Make the VPN reachable, either through a single forwarded VPN port, or with another method if your provider blocks incoming connections.
- Install the client on laptops, phones and tablets.
- Test it from outside your network, for example on mobile data.
Common snags
Some broadband providers place customers behind a shared address, known as CGNAT, which stops incoming connections. A public address, a different method of connecting or a small cloud-hosted relay can solve it. Your home address can also change, which a dynamic DNS service handles.
Keep it secure
- Use modern protocols, and keep router and NAS firmware updated.
- Use a separate key for every device and remove old ones.
- Do not leave other services, such as remote desktop, open directly to the internet.
- Give VPN users only the access they need.
That last point matters. Our guides on whether remote desktop is safe and accessing a NAS without opening ports show how a home VPN keeps those tools hidden from the internet. For a wider look at the risks, read how to access your home network remotely without getting hacked.

Frequently asked questions
No. A consumer VPN app sends your traffic through the provider’s servers. To reach your home files, PC or cameras you need a VPN that connects back to your own home network.
Not always. A dynamic DNS service can keep a changing address reachable. Some providers use shared addresses that make inbound connections harder, and a different approach is needed in that case.
It can be very secure when set up correctly with modern protocols, strong keys, updated firmware and no unnecessary open services. A poor setup can be risky.
WireGuard is fast, modern and simple, and OpenVPN is mature and widely supported. Many modern routers and NAS devices support one or both.
Your speed away from home is mainly limited by your home broadband upload speed, not by the VPN itself.
