What is a VPN and why run it on a Cudy router?

A VPN creates an encrypted tunnel between your home network and the VPN server, shielding your data from outsiders and masking your public IP.
Running a VPN on your Cudy router propagates protection to every device on your network—phones, laptops, smart TVs, and IoT devices—without needing individual VPN apps.
The main gain is convenience and broad coverage; the main trade-off is potential speed reduction, depending on the server and protocol.

Do I need a VPN on my Cudy router or can I install on individual devices?

If you want universal protection and a single point of management, router-level VPN is ideal.
If you mainly want to access home resources securely or only need VPN on a few devices, installing on those devices might be simpler and faster.
You can also configure a split-tunnel or per-device routing if your Cudy firmware supports it, allowing some devices to use the VPN while others stay on your regular internet.
