About the cloud server you are using

We are an AR development company in Japan.We are planning to develop AR for the government, and in Japan, the government has a assessment of system security. (Information system Security Management and Assessment Program)There are cloud services that conforming the security requirements of the government are registered, and if applicable, can be introduced smoothly.They are particularly concerned about servers, and AWS and GCP are already registered, can you tell me about the cloud servers you use?I look forward to your reply.

Best regards.
