Hey @Max_T,
If it is n8n desktop something like ngrok would do the job unless you had your own domain and wanted to do some port forwarding.
As for if it is safer… it depends on what you mean by safer. ngrok was just the first one I thought of but there are a few services that do what ngrok does.
I did make a very quick guide last year before I started here on how you can configure desktop to use ngrok which you can find here: N8n Desktop custom Webhook url ngrok - #4 by Jon
