Does Qualys VMDR detect quantum-vulnerable cryptography?

Qualys VMDR focuses on classical CVE-based vulnerability management. It does not provide quantum-specific risk scoring, HNDL exposure analysis, or PQC migration guidance. QScout is purpose-built for post-quantum cryptographic risk assessment.

Can QScout replace Qualys for vulnerability management?

No. QScout focuses specifically on cryptographic and quantum risk. Qualys VMDR covers broad classical vulnerability management including patch management and asset inventory. Many organizations use both tools for complementary coverage.

Does QScout provide a scoped snapshot like Qualys SSL Labs?

QScout returns a scoped snapshot with TLS grade, HNDL score, and compliance mapping after business-email verification.

Which compliance frameworks does QScout map to that Qualys does not?

QScout maps findings into major compliance frameworks including CNSA 2.0 and SWIFT CSP v2026, which cover PQC-specific mandates. Qualys VMDR focuses on classical compliance frameworks like PCI DSS and CIS Benchmarks.

Competitive Analysis

QScout vs. Qualys VMDR

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.

1. Quantum Risk Detection

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.

When to Choose Each Tool

Choose QScout when

You need to quantify quantum-specific cryptographic risk
CNSA 2.0 or SWIFT CSP v2026 compliance mapping is required
You want a QScout scoped snapshot with HNDL scoring after business-email verification
You need a CBOM with quantum vulnerability classification
Board-ready quantum risk reporting is a deliverable

Choose Qualys VMDR when

You need broad CVE-based vulnerability management
Patch management and remediation tracking is the priority
Agent-based continuous monitoring across large asset fleets
Container and cloud workload security scanning is needed
Classical compliance (PCI DSS, CIS) is the primary driver

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.
