Simeon Cloud is an identity and device management service that provides tools to manage and secure devices and applications in the cloud, especially for organizations using Microsoft 365. It enables automation of common administrative tasks such as user and license management, deployment of security policies, and provides visibility into states and activities of devices in the network. The service is a response to the mass migration of organizations to Microsoft 365 that need to ensure the consistency of their IT environment and do not want to spend hundreds of hours on manual configuration.
