Provides solid functionality and allows room for enhancing content management and support services
They can improve their CDR content profile and some anti-spam features. They don't have any direct script to run to add personalization, and we have to do it manually one by one. There are many tasks which we have to complete individually. We can't import files into the Fortinet FortiMail Cloud sensors. That's a drawback, as they need to provide a feature to import files. We can make the format, but we cannot import the file into Fortinet FortiMail Cloud. Additionally, in Fortinet FortiMail Cloud, not in FortiSandbox, they need to improve the block and allow list functionality to block URLs and allow specific types of URLs or regex.
