Manage the Cryptographic Risk Quantum Computing Will Introduce
Quantum computing has the potential to render widely used public-key cryptography, including RSA and elliptic-curve cryptography, ineffective. The immediate challenge is not predicting when a cryptographically relevant quantum computer will arrive, but understanding how long sensitive information must remain protected and how long it will take to replace cryptography embedded across technology and services. Information captured today may retain its value for years, creating exposure where encrypted data is collected now for decryption in the future.
The transition to post-quantum cryptography is already underway. NIST has finalised its first post-quantum cryptographic standards and recommends organisations begin migration rather than wait for quantum capability to mature. Meridian Cyber helps organisations identify where vulnerable cryptography is used, assess the exposure it creates and establish a controlled path to migration. We map cryptographic dependencies across applications, infrastructure, data flows and third parties, then prioritise action according to data sensitivity, business criticality, algorithm exposure and technology lifecycle.
- Gain visibility of vulnerable cryptography across systems, applications, data, certificates and third-party services.
- Prioritise migration according to data sensitivity, retention periods, business criticality and cryptographic exposure.
- Develop a transition roadmap aligned to technology lifecycles, vendor readiness and post-quantum standards.
- Build crypto-agility into architecture, policy and procurement so future cryptographic change can be managed efficiently
Discover
Identify where cryptography is used across systems, applications, data flows and third parties, creating a clear inventory of critical dependencies.
Plan
Develop a sequenced transition to post-quantum cryptography, aligned to technology lifecycles, vendor readiness, business dependencies and implementation complexity.
Assess
Assess cryptographic exposure against data sensitivity, retention periods, business criticality and algorithm risk to establish clear priorities for migration.
Adapt
Build crypto-agility into architecture, policy and procurement so cryptographic standards and algorithms can be changed efficiently as requirements evolve.
Our Quantum Readiness
Services
Meridian Cyber helps organisations prepare for the transition to post-quantum cryptography by establishing where cryptography is used, assessing exposure and defining a practical path to migration. Our services support cryptographic discovery, risk prioritisation, transition planning and crypto-agility, aligned to emerging standards and your technology lifecycle.
Cryptographic Inventory (Bill of Materials)
Establish a structured inventory of cryptographic algorithms, keys, certificates, protocols and libraries across applications, infrastructure and third-party services. This provides the baseline for identifying vulnerable dependencies and planning migration.
Exposure & Harvest-Now-Decrypt-Later Assessment
Assess cryptographic dependencies against data sensitivity, retention periods, algorithm exposure and business criticality to identify where long-lived information may be at risk and prioritise transition activity.
Quantum Transition Roadmap
Develop a phased migration roadmap to NIST-standardised post-quantum cryptography, including ML-KEM and ML-DSA where appropriate, sequenced against technology lifecycles, vendor readiness and critical dependencies.
Quantum Readiness Policy
Define the governance required for post-quantum transition, including cryptographic standards, ownership, lifecycle requirements, procurement expectations, exception management and ongoing maintenance of the cryptographic inventory.
Crypto-Agility Design Brief
Establish architecture principles and technical patterns that allow cryptographic algorithms and protocols to change without major system redesign, supporting post-quantum migration and future standards transitions.
Executive Briefing
Translate cryptographic exposure, migration priorities and investment requirements into clear business context for executives and boards, supporting informed decisions on quantum risk, sequencing and readiness.
