Qtangl vs DigiCert
Qtangl vs DigiCert — PQC Readiness Comparison (2026)
CLM and PKI leader with PQC issuance — cert discovery as CBOM foundation.
Land the point: Keep DigiCert for issuance; we inventory the full crypto surface and prove migration.
Their pitch
Trust Lifecycle Manager for cert discovery, Device Trust Manager, PKILINT, and private CA with ML-DSA/SLH-DSA issuance.

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 |
| DigiCert | partial | partial | no | partial | yes |
Where Qtangl wins

- Mosca HNDL and signed public verify
- Agentless external breadth
Where DigiCert wins
- Cert issuance and CLM at enterprise scale
- Organizations standardizing on DigiCert PKI
We acknowledge competitor strengths — never disparage. Choose based on your program scope.
When to choose DigiCert
Cert issuance, CLM, and PKI operations are the primary scope.
When to choose Qtangl
You need PQC posture across TLS, JWKS, SSH, and email — plus verifiable evidence, not just managed certificates.

FAQ
When should we choose DigiCert over Qtangl?
PKI-centric programs where certificate issuance and CLM are the core investment.
When should we choose Qtangl over DigiCert?
Security teams needing full-surface PQC inventory, Mosca HNDL, 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.
