MTCS

MTCS Compliance refers to the Multi-Tier Cloud Security standard, a security framework built on ISO 27001/02. It defines three security tiers for cloud service providers, with Level 3 being the most stringent. MTCS helps organisations understand the security posture of cloud platforms and ensures providers meet robust, industry-aligned cloud security controls.

MTCS builds on ISO 27001 but goes further by offering cloud-specific, tiered security requirements. While ISO 27001 covers general information security management, MTCS Compliance adds cloud-focused controls such as data sovereignty, tenancy isolation, security testing, and cloud operations standards, offering greater depth for high-impact cloud environments.

MTCS Level 3 is the highest tier of MTCS Compliance, designed for organisations with strict regulatory and security needs. It ensures the cloud provider meets advanced requirements for governance, risk management, data protection, encryption, and resilience. This level is essential for industries where data sensitivity and operational integrity are critical.

Tata Communications’ Vayu Cloud platform achieves MTCS Compliance through Level 3 certification, implementing strong controls across governance, audit logging, secure configuration, encryption, access management, and disaster recovery. These measures ensure high-security standards for Singapore-based workloads and regulated industries requiring advanced cloud protection.

Organisations can ensure MTCS Compliance by choosing cloud providers certified under MTCS, reviewing their security controls, and verifying adherence to data retention, sovereignty, DR, and operational requirements. They should also assess shared responsibility models, enforce strong governance, and continuously monitor security practices to stay aligned with MTCS guidelines.

MTCS enhances data protection by applying tiered controls covering identity security, encryption, incident response, monitoring, virtualisation security, and business continuity. Through MTCS Compliance, cloud providers must disclose and implement strong safeguards across governance, infrastructure, and operations, ensuring data is secure, traceable, and protected against cloud-specific risks.

Enterprises gain higher trust, improved security, regulatory readiness, and stronger risk management with Tata Communications’ MTCS Compliance. Level 3 certification ensures advanced protection for mission-critical workloads, secure isolation for multi-tenant environments, and robust operational controls, allowing organisations to adopt cloud confidently and securely.
