What is Cryptographic Posture Management (CPM)?
CPM is the 2026 label for post-quantum readiness tooling — inventory, risk, drift, and evidence. Here is how it differs from adjacent categories buyers conflate.
CPM in one paragraph
Cryptographic Posture Management (CPM) is continuous visibility into where cryptography lives in your estate, which algorithms are quantum-vulnerable, how risk maps to compliance deadlines, and whether remediation is proven — not just claimed. The standard artifact is the CycloneDX CBOM.
Adjacent categories (and how we differ)
| Category | Overlap | CPM / Qtangl difference |
|---|---|---|
| CLM | Cert inventory | Quantum-vuln class + Mosca HNDL + verify |
| ASM | External discovery | Crypto assets, not general vulns |
| GRC | Framework mapping | Crypto-specific signed evidence |
| Key management | Key material | Orchestrate + verify; don't store keys |
| PQ-TLS vendors | Hybrid TLS | Assess + prove, not just enable |
