Quantum Readiness Assessment

1. Executive summary

Quantum computing represents an existential threat to current cryptographic systems. Organizations must assess their quantum readiness now to protect sensitive data and ensure business continuity in the post-quantum era. This assessment framework helps organizations evaluate their current state and plan for quantum-resistant security.

2. Quantum threat timeline

Understanding the quantum threat timeline is crucial for prioritizing readiness efforts:

Current state (2026)

• • Noisy intermediate-scale quantum (NISQ) computers exist
• • Limited practical applications beyond research
• • Classical cryptography remains secure
• • "Harvest now, decrypt later" attacks may be occurring

Near-term (2026-2030)

• • Error-corrected quantum computers may emerge
• • Post-quantum standards will be finalized
• • Early quantum advantage in specific applications
• • Critical need for quantum-resistant systems

Long-term (2030+)

• • Practical quantum computers capable of breaking RSA/ECC
• • Classical cryptography becomes obsolete
• • Quantum-resistant systems become mandatory
• • New quantum-based cryptographic systems emerge

3. Readiness assessment framework

Our quantum readiness assessment evaluates organizations across five key dimensions:

Cryptographic inventory (25%)

• • Complete mapping of all cryptographic systems
• • Identification of quantum-vulnerable algorithms
• • Assessment of data sensitivity and retention periods
• • Documentation of cryptographic dependencies

Risk assessment (25%)

• • Evaluation of threat models and attack vectors
• • Analysis of data exposure and business impact
• • Assessment of regulatory and compliance requirements
• • Identification of critical systems and dependencies

Technical readiness (20%)

• • Current cryptographic implementation quality
• • Infrastructure modernization capabilities
• • Integration and interoperability considerations
• • Performance and scalability requirements

Organizational readiness (15%)

• • Leadership commitment and resource allocation
• • Staff expertise and training programs
• • Change management and communication strategies
• • Vendor relationships and procurement processes

Implementation planning (15%)

• • Migration strategy and timeline development
• • Testing and validation procedures
• • Rollback and contingency planning
• • Monitoring and maintenance procedures

4. Critical systems evaluation

Certain systems require immediate attention due to their criticality and quantum vulnerability:

High-priority systems

• • PKI infrastructure - Certificate authorities and key management
• • Authentication systems - SSO, MFA, and identity providers
• • Financial systems - Payment processing and banking applications
• • Healthcare systems - Patient data and medical records
• • Government systems - Classified and sensitive government data

Medium-priority systems

• • Communication systems - Email, messaging, and collaboration tools
• • Cloud services - SaaS applications and cloud storage
• • IoT devices - Connected devices and embedded systems
• • Supply chain systems - Vendor and partner communications

Lower-priority systems

• • Marketing systems - Customer relationship management
• • Internal tools - HR systems and internal applications
• • Legacy systems - Older applications with limited exposure

5. Migration planning

Successful quantum migration requires careful planning and phased implementation:

Phase 1: Foundation (Months 1-6)

• • Complete cryptographic inventory and risk assessment
• • Establish quantum readiness governance and team
• • Develop migration strategy and timeline
• • Begin vendor evaluation and selection

Phase 2: Preparation (Months 6-18)

• • Implement hybrid classical/post-quantum systems
• • Conduct pilot deployments and testing
• • Train staff and update procedures
• • Establish monitoring and validation processes

Phase 3: Migration (Months 18-36)

• • Deploy post-quantum systems across critical infrastructure
• • Migrate high-priority systems and applications
• • Update policies and procedures
• • Conduct security testing and validation

Phase 4: Optimization (Months 36+)

• • Complete migration of remaining systems
• • Optimize performance and efficiency
• • Maintain and update quantum-resistant systems
• • Prepare for future quantum advances

6. Risk mitigation strategies

Organizations can implement several strategies to mitigate quantum-related risks:

Cryptographic agility

Design systems with the ability to quickly update cryptographic algorithms without major architectural changes.

Defense in depth

Implement multiple layers of security controls, including quantum-resistant algorithms, to reduce overall risk exposure.

Data minimization

Reduce the amount of sensitive data stored and transmitted, limiting potential exposure to future quantum attacks.

Zero trust architecture

Implement zero trust principles that assume all communications may be compromised, reducing reliance on perimeter security.

Continuous monitoring

Establish monitoring and detection capabilities to identify potential quantum-related threats and attacks.
