integrator.io does not control the access, NetSuite does. For your current NetSuite-based dashboard, your NetSuite administrator defines roles & permissions in NetSuite and grants those roles & permissions to a user. If the NetSuite administrator takes away the user's access or permissions, they won't be able to see the dashboard. This does not change with integrator.io. integrator.io uses the credentials that have been assigned to you for NetSuite and will always respect the permissions setup in NetSuite.
