Qtangl vs Open source / DIY
Qtangl vs Open Source PQC Tools — Comparison (2026)
Free NIST-aligned primitives and scanners — assemble your own program.
Land the point: OQS gives you parts; we give you the assembled, auditable program.
Their pitch
Open-source tooling: OQS/liboqs primitives, IBM CBOMkit, QRAMM/CryptoScan for code scanning and CBOM generation.
Discovery: Point scanners and libraries assembled by internal engineering teams.

Capability radar
Relative scores (0–5) across six buyer dimensions. Qtangl vs Open source / DIY.
| Dimension | Qtangl | Open source / DIY |
|---|---|---|
| Time to inventory | 5 | 2 |
| Verifiable evidence | 5 | 1 |
| Discovery depth | 4 | 2 |
| Platform breadth | 4 | 1 |
| Mid-market affordability | 4 | 5 |
| Self-serve path | 5 | 2 |
Discovery method coverage
No single discovery method is complete — NIST guidance recommends combining 2–3. Each vendor anchors to a primary method with characteristic blind spots.
| Vendor | Agentless external | Host / endpoint | Source / binary | Key / KMS | Certificate / CLM |
|---|---|---|---|---|---|
| Qtangl | yes | yes | yes | yes | yes |
| Open source / DIY | partial | no | partial | no | no |
Where Qtangl wins
- Productized workflow: orchestration, report, drift, compliance crosswalk
- Signed verifiable evidence and Readiness Passport
- Total cost of engineer time plus audit prep
Where Open source / DIY wins
- Teams with spare engineering capacity to assemble tooling
- Research and primitive validation use cases
We acknowledge competitor strengths — never disparage. Choose based on your program scope.
When to choose Open source / DIY
You have engineering capacity to assemble scanners and maintain tooling indefinitely.
When to choose Qtangl
You need an assembled, auditable program — not a parts bin. Qtangl builds on OQS; we don't replace it.
FAQ
When should we choose open source / DIY over Qtangl?
Engineering teams with capacity to build and maintain custom scanner pipelines indefinitely.
When should we choose Qtangl over open source / DIY?
Security programs needing productized inventory, drift, compliance mapping, and signed auditor-verifiable evidence.
Can we use both together?
Often yes. Many regulated teams keep a discovery incumbent for depth and layer Qtangl as the neutral evidence system of record — signed reports, transparency log, and Readiness Passport auditors verify independently.
