You have a device that is not used anymore, and you still get the weekly and daily reports from the SecuReporter?
Here is a way how to disable the daily and weekly reports!
Open the SecuReporter web page and login with your credentials -> https://secureporter.cloudcnm.zyxel.com/
Choose the organization and device from where you get the reports:
Go to the following section:
Report -> Configuration
Choose the daily or weekly report to delete, disable or edit it and check if there are separate email addresses added. If needed, remove them and save this section.
Done, now you will receive reports based on your settings.
