Qualys VMDR is the enterprise standard for classical vulnerability management. QScout is purpose-built for PQC risk assessment. Different problems, different tools — here is where each one leads.
Post-quantum cryptographic risk is a distinct threat category from classical CVEs. QScout is built specifically for this domain, including HNDL scoring and migration deadline calculation.
| Capability | QScout | Qualys VMDR |
|---|---|---|
| Quantum-vulnerable algorithm identification | ✓ | ✗ |
| HNDL risk scoring (0-100) | ✓ | ✗ |
| PQC readiness assessment | ✓ | ✗ |
| Hybrid TLS detection (classical + PQC) | ✓ | ✗ |
| ML-KEM / ML-DSA readiness check | ✓ | ✗ |
| Nation-state adversary timeline mapping | ✓ | ✗ |
Qualys VMDR excels at classical vulnerability management — CVE detection, patch management, and broad asset inventory. QScout does not attempt to replace this.
| Capability | QScout | Qualys VMDR |
|---|---|---|
| CVE-based vulnerability detection | ✗ | ✓ |
| Patch management | ✗ | ✓ |
| Asset inventory & discovery | Crypto assets only | ✓ |
| Agent-based internal scanning | Scoped | ✓ |
| Container security scanning | ✗ | ✓ |
| Cloud workload protection | ✗ | ✓ |
How each tool delivers results, maps to compliance, and fits into enterprise infrastructure.
| Dimension | QScout | Qualys VMDR |
|---|---|---|
| QScout Free executive snapshot | Typically 3-8 minutes, business-email verified | SSL Labs only |
| Compliance frameworks mapped | 15 (incl. NIST SP 800-53, GLBA, CNSA 2.0, SWIFT CSP v2026) | PCI DSS, CIS Benchmarks |
| Deterministic + governed review | ✓ | ✗ |
| CBOM export (CycloneDX 1.7) | Scoped | ✗ |
| Deployment model | Dedicated runtime + Azure Marketplace | SaaS + agent |
| Procurement path | QScout Free snapshot + scoped engagement | Subscription |
Many enterprises run both tools. Qualys VMDR handles classical vulnerability management; QScout adds the quantum risk layer that classical scanners were not designed to address.
