Less uncertainty.
More useful evidence.
A transparent score is the start—not the conclusion. See what was observed, what needs attention and what remains unverified.
01 / Observe
Start with a domain. Not an installation.
Submit a domain you are authorized to scan. PlancKey checks public DNS and requests available HTTPS observations. No credentials or access to your internal systems are needed.

Public keys and issuer signatures

Score distributions and adoption signals put external evidence in context.
Find opt-in subscribers
Public listings require consent and an active subscription. Subscriber onboarding is still being established.
Private by default
Free-scan names and scores are not listed publicly. Small benchmark groups are withheld.
The Index reflects observed PQC support, not a security certification or proof that an organization is well secured.
Check yourself.
Check your vendors.
For security teams
Bring dated external evidence to customer questionnaires and internal planning. Use the findings to start a broader discussion about your cryptographic inventory.
Scan your domainFor vendor-risk teams and partners
With a supplier’s permission, review its public-domain PQC signals. Keep the scoped PDF report as one input to procurement and third-party risk reviews.
Explore partnershipsThe standards are here.
Preparation takes time.
Long-lived data needs a long-term plan. An external scan won’t answer every question, but it gives you a practical place to begin.
Explore the learning centrePost-quantum standards are published
NIST finalized FIPS 203, 204 and 205 in August 2024: standards for ML-KEM, ML-DSA and SLH-DSA.
Understand PQCData can be harvested today
Harvest-now, decrypt-later risk concerns encrypted data collected now for potential future decryption. Priorities depend on how long your data must stay confidential.
Understand HNDLMigration is more than replacing an algorithm
Inventory, dependencies and testing all matter. Published transition guidance varies by system and jurisdiction; it is not a universal business deadline.
Understand crypto agilityMeasure first.
Make better decisions.
PlancKey takes its name from Max Planck and the beginnings of quantum theory. Our approach is practical: make the evidence clear, be honest about its limits and help you choose the next step.
Need to go beyond public endpoints? Internal discovery, migration planning and monitoring are proposed paid engagements, with scope and availability agreed before purchase.
No “quantum-proof” promises. The scan covers public DNS and available HTTPS evidence—not internal systems, mail encryption, VPNs or complete quantum readiness.
Our safeguardsStart with your domain.
Get public evidence. Review your Q-Signal™ report. Decide what to investigate next.
Scan domains you are authorized to assess, or suppliers for legitimate due diligence. HTTPS findings may take several minutes or be unavailable.
