Competitive landscape
Post-quantum readiness vendors compared (2026)
The post-quantum readiness market consolidated under Cryptographic Posture Management (CPM) in 2026. Here is an honest map of who does what — and where signed, verifiable evidence differentiates Qtangl.
The category in one sentence
Post-quantum readiness (also crypto-agility, CPM) means inventorying quantum-vulnerable cryptography, monitoring drift, and proving remediation before Q-Day — with CycloneDX CBOM as the standard artifact.
Tier A — Direct PQC platforms
| Vendor | Primary discovery | Qtangl wins when |
|---|---|---|
| SandboxAQ | Host agents / sensors | Mid-market speed + public verify |
| Keyfactor | Host agents + CLM | Agentless external baseline |
| QuSecure | Network overlay + R3 Recon | Assessment before overlay |
| IBM Quantum Safe | Code scan + runtime | External baseline this week |
| Fortanix | KMS/HSM keys | TLS/JWKS/SSH + Mosca HNDL |
| Palo Alto | NGFW telemetry | Standalone portable evidence |
Tier B — Pure-play twins
Qinsight, ExeQuantum, and Encryption Consulting all ship fast inventory + CBOM. That core is now table stakes. Qtangl wins on signed public verify and mid-market packaging.
What actually differentiates
- Signed + publicly verifiable evidence — Qtangl is the only vendor in our matrix marked Yes for independent offline verification.
- Mid-market self-serve — transparent pricing, minutes-to-inventory.
- Honest scope — agentless external baseline; layer onto incumbents for depth.
