Hello Claire,
DX is inherently secure in the sense that it does not traverse the public internet. It’s as though you’re connected to your local network. So it is private. You can achieve the same ‘private connection’ through a VPN. A VPN is usually used to secure connections over the internet. Depending on the security requirement, you can also use a VPN with DX to ‘enforce’ security. But it does not mean that DX is insecure.
Let me know if this helps.
