It depends how big/real the “security” you are looking for is. You can also configure dedicated roles and limit access according to the logged-in user and their role. You can also read on mapView server-side who is logged in (IP address, etc.) using System variables and implement some logic based on this. But to be honest… the real security for me would be a simplified, second visualization designed for remote users. You can reuse contents for that, so in the end it would not be so much work.. but it depends of complexity and size of your visualization, of course… I would be interested in hearing about your solution
