    Information security has defined principles, responsibilities, and supervision. We identify risks and select safeguards to protect the confidentiality, integrity, and availability of data. Scope of standard (opens in a new tab)

  • ISO/IEC 27017: cloud service security

    We apply information protection principles taking into account the specifics of the cloud. These include securing the environment and dividing responsibility between the provider and the service user. Scope of standard (opens in a new tab)

  • ISO/IEC 27018: protection of personal data in the cloud
