The Multi-Tier Cloud Security (MTCS) Singapore Standard (SS)584
is a cloud security certification managed by the Singapore Info-comm Media Development
Authority (IMDA). The standard has three tiers designed to certify cloud service providers at
different levels of operational security, with Tier 3 having the most stringent requirements.
At the conclusion of the audit conducted by an independent MTCS Certifying Body, 114 Google
Cloud services and 20 datacenter sites received Tier 3 certification. The scope of services
included in the certification highlights Google Cloud's ongoing and continuous commitment to
ensuring sound operational and security controls across all three service models —
Infrastructure-as-a-Service (Iaas), Platform-as-a-Service (PaaS), and Software-as-a-Service
Google Cloud Platform and G Suite are certified as MTCS compliant.
