HRT Quantum Resilience Advisory

Prepare your organization for Q-Day.

Prepare your organization for Q-Day: understand cryptographic exposure, establish ownership and plan a risk-led transition to post-quantum security.

Why prepare

A migration programme, not a single product change.

Q-Day is shorthand for a future point when a sufficiently capable quantum computer could break widely used public-key cryptography. It is not a confirmed calendar date. Preparation focuses on risk and migration dependencies rather than a countdown. [3]

NIST has published post-quantum cryptographic standards for key establishment and digital signatures. These provide a foundation for organizations planning their transition. [1]

Preparation includes understanding cryptographic dependencies, prioritizing risk and testing interoperability. The NCCoE migration project addresses discovery and interoperability as distinct workstreams. [2]

HRT's role is to translate the readiness questions into a scoped assessment, a decision framework and a practical roadmap for your organization.

Advisory engagements

Start where your organization needs clarity.

Select a focused engagement or a connected programme. The deliverables below are indicative; scope and responsibilities are agreed before work begins.

Quantum Risk Executive Advisory

Give boards, CIOs and CISOs a common view of the risk, the decisions ahead and the questions to ask their technology teams.

Indicative deliverables

  • Board or executive briefing and decision questions
  • Initial exposure priorities and leadership actions

Quantum-Readiness Assessment

Review cryptographic visibility, critical dependencies, sensitive information and organizational readiness within an agreed scope.

Indicative deliverables

  • Scoped cryptographic inventory and evidence gaps
  • Risk classification and readiness scorecard
  • Prioritized findings and accountable owners

PQC Migration Strategy

Plan the transition to post-quantum cryptography (PQC) around business criticality, vendor dependencies, testing and change governance.

Indicative deliverables

  • Target architecture and phased migration roadmap
  • Vendor dependencies and pilot priorities
  • Budget assumptions, ownership and decision gates

PQC Transformation Advisory

Support programme governance, vendor evaluation and implementation planning as your organization prepares and oversees the transition.

Indicative deliverables

  • Governance and vendor-review support
  • Migration oversight and progress-review criteria

HRT readiness framework

Five dimensions. An evidence-led view of readiness.

The review connects technical dependencies with business exposure and organizational ownership. Unknowns are documented, not hidden behind a readiness score.

This is HRT's advisory structure, informed by public guidance. It is not a certification or a NIST-endorsed assessment.

  1. Cryptographic Visibility

    Where do you depend on cryptography?

    Identify relevant applications, certificates, keys, protocols and third-party dependencies, with evidence owners for each area.

  2. Quantum Risk Exposure

    What needs protection for the longest?

    Consider sensitive data lifetimes, business criticality and the consequences of exposure when setting priorities.

  3. Technical Migration Readiness

    What must change, and how will it be tested?

    Review system constraints, integration dependencies, interoperability, test environments and recovery planning.

  4. Vendor and Supply-Chain Readiness

    Which changes depend on other organizations?

    Review vendor roadmaps, supported products, contract dependencies and the evidence needed for procurement decisions.

  5. Governance and Cryptographic Agility

    Who owns the transition and future changes?

    Define accountability, policies and change processes that help the organization adapt its cryptographic choices over time.

Scope and expectations

A clear basis for engagement.

What is Q-Day?

Q-Day is shorthand for a future point when a sufficiently capable quantum computer could break widely used public-key cryptography. It is not a confirmed calendar date. The practical task is to understand exposure and plan the transition, rather than predict the day.

Is this a quantum-computing implementation service?

No. The focus is cybersecurity readiness and the transition of cryptographic dependencies, not building quantum computers or providing a proprietary cryptographic product.

Can we begin without a complete cryptographic inventory?

Yes. An initial advisory engagement can define the inventory scope, information owners and evidence required. Missing evidence is recorded as a gap, not treated as proof of readiness.

Does an assessment certify that an organization is quantum-safe?

No. It is an advisory assessment within an agreed scope, not a certification, a guarantee of security or an endorsement from NIST. Findings depend on available evidence and require review as systems change.

What is included in an engagement?

Scope, deliverables, responsibilities and access arrangements are agreed before work begins. Production changes, penetration testing and cryptographic implementation are not implied by an advisory engagement and require separate authorization and specialist delivery arrangements.

Begin with an informed conversation.

Share your objectives and operating context. Do not email private keys, credentials or sensitive system inventories.
