Suggestions for protecting Wappler development

When deploying my Wappler app/site to a customer.
I currently have all the Wappler source files on their IIS Web Server in the c:/inetpub/wwwroot/myapp/ folder as it connects to a MS SQL Server on their LAN which cannot be accessed directly from an external IP.

I am trying to work out whether its possible to host the server connect .asp files and as many Wappler core files on one of my web servers. So all the data connections work from their web server, but difficult to copy onto another server.

Essentially I would like to protect all the hard work thats gone in to building the pages.

Thanks in advance.
