QKD Sales Qualification and Objection Handler
Seven questions. An instant qualification index for QKD prospects, with technically accurate objection responses tailored to the prospect's profile.
- Based on the QKD scoring model: threat model, sensitivity, topology, infrastructure, budget
- Objection responses filtered to the prospect's specific profile — not a generic FAQ
- Talking points selected from a pre-approved library aligned to the prospect's answers

How this assessment works
This tool calculates a Qualification Index (QI) from five scored inputs: threat model (24%), data sensitivity (24%), network topology (19%), existing infrastructure (19%), and budget (14%). Sector and cryptographic posture apply modifiers and disqualifying flags rather than direct scores.
The QI runs from 0 to 100. Four classification tiers map to QI ranges: Strong Fit (70+), Conditional Fit (50–69), Hybrid Recommended (30–49), PQC Recommended (0–29). Modifiers and flags can override the numerical result.
The model is calibrated to return PQC Recommended for the majority of prospects. Strong Fit requires a genuine nation-state HNDL threat, high data sensitivity, and feasible infrastructure.
Which sector best describes this prospect's organisation?
QKD has genuine operational use cases in a small number of sectors. This determines whether the prospect is in a category where QKD deployments are occurring, and tailors the result and objection responses accordingly.

What is the primary driver behind this prospect's interest in QKD?
QKD addresses a specific threat: a well-resourced adversary intercepting data for future decryption (Harvest Now, Decrypt Later) where information-theoretic rather than computational security is required. Understanding the actual driver is essential before any technology recommendation.

What is the highest classification level of data on the links this prospect wants to protect?
QKD's information-theoretic security guarantee is most justifiable where future decryption would be catastrophic. For most commercially sensitive data, PQC provides sufficient security at far lower deployment cost.

What is the network topology between the sites this prospect needs to protect?
QKD is a point-to-point physical technology. A direct optical fibre path between two endpoints is optimal. Each additional hop requires a trusted node — a physically secured relay with a different threat model. Mesh networks, cloud-first architectures, and wide-area networks are not compatible with current QKD infrastructure.

What physical infrastructure is available between the sites to be protected?
QKD requires a dedicated quantum channel — typically a dark fibre strand with no active traffic. Co-propagating classical signals introduce noise; wavelength-division multiplexing mitigates this at some performance cost. Dark fibre availability is the primary practical constraint on QKD deployment.

What is the approximate capital budget available for this deployment?
A complete QKD system ranges from approximately £150,000–£500,000 for a basic point-to-point link, rising substantially for multi-site deployments. Ongoing costs — dark fibre lease, maintenance, key management — should be included in the assessment.

Where is this organisation on the post-quantum cryptography migration journey?
Key exchange is only one element of a cryptographic architecture. Links protected by QKD also need quantum-resistant authentication and PQC or symmetric encryption for data at rest. An organisation that has not assessed its cryptographic posture needs PQC migration planning before QKD procurement is meaningful.
