Rank 4 / Established band / Confidence MOD

IBM Guardium + Quantum Safe

IBM / PQC discovery capability record for edition 2026.5.

7.39Index score / 10

IBM authored the CBOM specification, and its open-source toolchain has been benchmarked against external ground truth. S09 S10 S23

Established MOD

Seven criterion scores

C18

Discovery

How broadly and deeply does the product find cryptographic assets?

C28.5

Evidence artifact

Does it produce a portable, verifiable record of what was found?

C37

Change detection

Can it detect and preserve material changes over time?

C46

Risk quantification

Does it turn inventory into a defensible migration priority?

C58

Correctness

Is detection accuracy measured against named ground truth?

C67

Remediation loop

Can a finding move through ownership, action and verified closure?

C77

Reporting

Can technical and executive readers understand and reuse the result?

What this record can support

The overall score is a weighted capability reading, not a laboratory accuracy result, market-share measure, certification grade or prediction of implementation success.

Evidence class D T and confidence MOD describe the reviewed evidence depth. A lower-confidence row is expected to move more as additional primary technical evidence is located.
