After more than two years, cloud services from the Microsoft Azure, Microsoft 365, Dynamics 365 and Power Platform families were entered into the cloud computing catalog of the eGovernment of the Czech Republic. The National Office for Cyber and Information Security (NÚKIB) and the Digital Information Agency (DIA) have confirmed the high level of security and operation of these services. Microsoft thus became the first trusted cloud provider whose services were tested and subsequently approved to the BÚ3 security level, which is the highest attainable level for public cloud services. Thanks to this inclusion, these services can also be used for the operation of Important Public Administration Information Systems.
