Quantum computers will soon be powerful enough to break today’s commonly used encryption algorithms. To stay secure, organisations must transition to post-quantum cryptography (PQC) – new, quantum-resistant methods that protect critical data and systems for the long term.
Our team combines deep experience in ISO-standard risk management and business continuity across both public and private sectors. We provide independent, vendor-neutral guidance so leadership teams can take confident, informed decisions about long-term resilience and compliance with emerging regulations.
PQC Ready is a UK-based consultancy specialising exclusively in helping organisations prepare for the post-quantum cryptography era. We were created when bodies such as the UK National Cyber Security Centre (NCSC) and global regulators began issuing migration guidance – revealing that many organisations lacked a realistic plan to move to quantum-safe systems.
We treat PQC as a strategic, organisation-wide transition that belongs in the boardroom, not as an isolated IT experiment. For governments, critical infrastructure operators, financial institutions, and data-intensive businesses, quantum risk is fundamentally about governance, continuity, and public trust.
Quantum computers are advancing quickly. Once they reach sufficient capability, they will be able to break widely used public-key encryption -the technology that protects identity systems, secure communications, financial transactions, and sensitive records. Such cryptographically relevant quantum computers threaten to disrupt operations of governmental organisations and private businesses alike.
A growing concern is “Store Now, Decrypt Later” attacks, in which adversaries capture encrypted data with the intention of unlocking it once quantum computers mature. Any information that must remain confidential for years – citizen data, health records, intellectual property, legal archives, infrastructure telemetry – is therefore already at risk if protected only by pre-quantum methods.
Moving to post-quantum cryptography is not a simple software patch. It affects identity and certificate management, key-management systems, vendor integrations, and long-lived data stores. For most organisations, becoming quantum-safe is a coordinated, multi-year transition requiring structured monitoring.
Regulators are acting now. NIST has selected the first post-quantum algorithms, and the NCSC and European authorities have outlined migration timelines. The message is clear: organisations must begin upgrading years before quantum machines become operational.
PQC Ready turns a complex future threat into a practical programme of action. We work with both technical teams and senior leadership to:
Identify and Assess
weak spots in your systems, where critical services, suppliers, and data are underpinned by vulnerable cryptography
Create and Draw Up
a phased, compliant PQC roadmap aligned with national guidance and your operational constraints
Prepare and Formulate
continuity measures so the organisation can operate safely if quantum capability emerges sooner than expected
Quantum risk will not wait for perfect timing or perfect budgets. Organisations whose operations rely on long-term confidentiality, service continuity, and public confidence should start planning now. If you are unsure where to begin – or need to translate regulatory expectations into concrete steps – PQC Ready is here to guide you.
