What is the Quantum-Safe Migration Handbook?
Cyber Security Agency of Singapore (CSA) introduced the Quantum-Safe Migration Handbook and the Quantum Readiness Index (QRI) as complementary resources to help organizations prepare for the transition to quantum-safe cryptography on July 16, 2026. The Quantum-Safe Migration Handbook provides practical guidance for planning and implementing a phased migration to post-quantum cryptography (PQC), while the QRI enables organizations to assess their readiness, identify capability gaps, and prioritize next steps.
The Quantum-Safe Migration Handbook provides practical guidance across five domains to assess quantum risks, identify cryptographic assets, build crypto agility, plan a phased migration to post-quantum cryptography (PQC), and adapt to evolving technologies and standards.
The handbook serves as a broad national reference; adoption falls into two categories: mandatory/regulated entities with strict national deadlines, and organizations strongly advised to align due to high risk.
- Mandatory & Regulated Entities (Strict Compliance)
- Critical Information Infrastructure (CII) Owners: Organizations operating essential services across 11 critical sectors: Banking & Finance, Energy, Healthcare, Info-communications, Water, Transportation, Government, Emergency Services. Mandatory Milestones:
- March 2027: Summit comprehensive quantum-safe migration plans to CSA
- 2028 – 2031: Ensure all new digital systems support quantum-safe tech starting in 2028, and complete full migration by end of 2031.
- Government Ministries & Public Sector Agencies: Agencies managing public data, citizen portals, digital identity platforms, and core civil service infrastructure.
- Critical Information Infrastructure (CII) Owners: Organizations operating essential services across 11 critical sectors: Banking & Finance, Energy, Healthcare, Info-communications, Water, Transportation, Government, Emergency Services. Mandatory Milestones:
- High-Priority Organizations (Strongly Advised to Align)
- Financial Institutions & FinTech
- Long-Shelf-Life Data Custodians
- Telcos & Cloud Service Providers
- IT Vendors & System Integrators

How Thales Helps with The Quantum-Safe Migration Handbook in Singapore?
Thales’s solutions, together with Professional Services, help organizations align with the CSA Quantum-Safe Migration Handbook by providing expert advisory, cryptographic assessments, migration planning, and trusted security solutions that accelerate quantum-safe readiness, strengthen cryptographic governance, and execute a structured transition to crypto-agile environments.
CSA Quantum-Safe Migration Handbook Compliance Solutions
Application Security
Protect applications and APIs at scale in the cloud, on-premises, or in a hybrid model. Our market leading product suite includes Web Application Firewall (WAF), protection against Distributed Denial of Service (DDoS) and malicious BOT attacks, security for APIs, and a secure Content Delivery Network (CDN).
Data Security
Discover and classify sensitive data across hybrid IT and automatically protect it anywhere, whether at rest, in motion, or in use, using encryption tokenization and key management. Thales solutions also identify, evaluate, and prioritize potential risks for accurate risk assessment as well as identify anomalous behavior, and monitor activity to verify compliance, allowing organizations to prioritize where to spend their efforts.
Identity & Access Management
Provide seamless, secure and trusted access to applications and digital services for customers, employees and partners. Our solutions limit the access of internal and external users based on their roles and context with granular access policies and Multi-Factor Authentication that help ensure that the right user is granted access to the right resource at the right time.

How Thales helps:
- Identify crown jewel applications and high-value information assets requiring priority protection.
- Provide visibility into where sensitive data is stored and protected, helping organizations focus migration on the systems with the greatest business impact.
How Thales helps:
- Build a cryptographic inventory using existing documentation, PKI records, HSM logs, and key management systems.
- Gain centralized visibility into managed cryptogra~phic assets—including encryption keys, certificates, HSMs, and cryptographic policies.
- Supplement with ACDI tools to discover cryptographic assets across applications, networks, and endpoints.
- Keep the cryptographic inventory up to date to support ongoing migration and crypto-agility.
How Thales helps:
- Protect high-value data with AES-256 encryption, tokenization, application data protection, and HSM-backed key security.
- Secure long-term confidential data (financial records, healthcare data, PII, intellectual property) that the handbook identifies as high-priority targets for Harvest-Now, Decrypt-Later attacks.
- Enforce strong encryption (for example, AES-256), centralized key management, and least-privilege access controls to reduce current risk before full PQC migration.
- Support security teams in understanding which assets are protected and demonstrate progress during migration planning with centralized auditing and reporting.
How Thales helps:
- Establish cryptographic governance with centralized management of keys, policies, and cryptographic assets, role-based administration, and separation of duties.
- Maintain a live cryptographic inventory with visibility into encryption keys, encryption policies, HSMs, and protected assets.
- Maintain cryptographic policies with centralized policy management for encryption, key usage, rotation, separation of duties, and access control.
- Offer automated generation, rotation, backup, archival, revocation, expiration, and destruction of keys.
