aemscan vs Qualys: 2026 Comparison
aemscan is a free vulnerability assessment tool. Qualys is a commercial vulnerability assessment tool by Oktacron. Compare features, ratings, integrations, and community reviews side by side to find the best vulnerability assessment fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security teams managing Adobe Experience Manager instances need aemscan because it's purpose-built for AEM's specific attack surface rather than generic web app scanning; the 186 GitHub stars and free pricing mean adoption is already happening in mid-market deployments where AEM security often gets overlooked. The tool excels at identifying configuration and component vulnerabilities that automated scanners designed for other platforms will miss. Skip this if your organization runs AEM at massive scale and needs centralized inventory and remediation workflows; aemscan is a targeted scanner, not a platform.
Enterprise security teams managing hybrid cloud infrastructure need Qualys for its ability to correlate vulnerability data across thousands of assets in real time, which cuts triage time against mid-size competitors. The platform covers ID.AM and DE.CM strongly, meaning you get asset discovery that actually stays current and continuous monitoring that flags drift without requiring manual refresh cycles. Skip this if you need deep application-layer scanning or CSPM capabilities bundled in; Qualys assumes you're running dedicated tools for those functions and focuses narrowly on vulnerability detection and risk ranking.
