CloudMonitor uses the same permissions as someone who would be viewing the costs and resources on your system, plus the data never leaves your cloud. All cost and resource information is stored securely in Azure within your Subscription with the same security controls backed by Azure Active Directory.
No 3rd party or Guest accounts need to be created for CloudMonitor to work – no external access is required to your system. Please ask your IT Team to contact us so we can have a chat about the security controls in place for CloudMonitor.
