Review Summary
Generated using AI from real user reviews
Qualys earns overwhelming praise for security effectiveness and ease of use, though support responsiveness is inconsistently reported. The vast majority of users—28 of 32 reviews rate it 4 or 5 stars—highlight strong security outcomes, intuitive interface, and reliable customer service. Many specifically commend the cloud agent and automated capabilities, with several noting noticeable security improvements within weeks of deployment.
One detailed 3-star review stands out as a significant outlier, however. That user experienced substantial friction with authenticated scans, module synchronisation issues (AssetView and ThreatProtect), and critically, severely delayed support response—describing a 6-month wait for a simple fix and generic first responses. This contrasts sharply with the consistent praise for support elsewhere, though a few reviews do mention Qualys being "very busy."
The product itself draws no serious functional criticism beyond the one account of syncing problems. Users consistently describe the platform as easy to navigate and effective at reducing security anxiety. For most buyers, Qualys appears to deliver on its core promise, but the one detailed negative experience suggests support quality may vary significantly or degrade under certain circumstances—worth probing in evaluation if your environment resembles that reviewer's setup.
