No. This is one of the key differences with CloudMonitor over other products that do cost optimization. In our opinion, it could be considered a security risk to send your private cloud data over the internet to a SaaS product or service. We think your data should stay firmly in your tenancy!
CloudMonitor will install to the Managed Resource Group and Subscription of your choice and run as normal cloud services. If you want to, you can monitor it and apply any policies and security policies in your organization to CloudMonitor itself.
No 3rd party or Guest accounts need to be created for CloudMonitor to work. Please ask your IT Team to contact us if they have any concerns so we can have a chat about the security controls in place for CloudMonitor.
