      To find if the consumer is getting the services and service level agreements that meet his needs is the responsibility of a consumer.
      It might happen that consumer wants to get the copy of the service provider's security control reports as well as other related information. The significant pointers the consumers wants to observe are access controls, authentication, data management and recovery, data sanitization, ownership of data, continuous monitoring, incident reporting and so on.
