I'm working through implementing ESRI's ArcGIS security implementation guidelines for ArcGIS Enterprise .
I note that one of the recommendations is to use an ArcGIS Online print service instead of the ArcGIS Server print service for publicly facing applications.
I found the the following print service
However, I as far as I'm aware I can't create and use custom Print Templates with this ArcGIS online print service. Therefore, I cant use the ArcGIS online solution and need to use a print service from my ArcGIS server.
The documentation above suggests that if you want to use a custom print service on an ArcGIS server then the Server itself should be in the DMZ. My enterprise configuration has the ArcGIS Server that hosts the print service behind a corporate firewall with a webadaptor in the DMZ. If all traffic is being routed through the webadaptor is this still a security risk?
If not and ESRI are going to recommending using an ArcGIS Online Print service then you should be able to create custom print templates?
