Nicki Møller - PeerSpot reviewer
Information Security Engineer at a manufacturing company with 5,001-10,000 employees
Enables automation and quick access to necessary information
One of the significant challenges Qualys is discovery, which I know Microsoft excels at. I can't recall how well Qualys performs this function; it seems I might be missing some details. However, if there's one key aspect to focus on, it's discovery—the ability to identify assets that you are not aware of, even when you can see they are present. Understanding what those assets are is crucial. With Qualys CyberSecurity Asset Management, it was very difficult to extract detections from the system. The features within Qualys are limited to what they have developed. Sometimes a complete overview is needed to push to a Power BI dashboard, Splunk, ServiceNow, or other platforms. The export process is incredibly challenging. We needed a developer to write a hundred-line Python script that would loop over certain assets due to export limitations. Qualys CyberSecurity Asset Management could improve its integration capabilities. While it generates substantial data, correlating it with other data sources can be challenging. The export process is difficult, and pre-built integrations with other tools could be enhanced for better process implementation.

Centralized analytics have strengthened patch visibility and support efficient regulatory reporting
From my experience, I assess the product's analytics capabilities as successful. It helped us significantly with patching and managing the risk of the patching process across all our environments, including network devices with Windows and Unix systems. The product covered several environments and gave us exactly what we needed in our environment. Tenable Security Center's centralized platform helped with risk assessment and management across our IT environments. It covered the patching process, and we previously faced many issues regarding how to patch different environments, how to monitor the patching process, and whether it was successful or not. We obtained good reports showing when patches were closed and the details of each patch, including who executed it and everything related to the patching process until it was closed. This gave us good details about the process which helped us significantly in our reporting and even in audits, whether internal or external. We learned how to close audit issues safely and successfully. We used the dashboards for real-time threat insights and extracted several dashboards from Tenable Security Center. We use these dashboards in our cybersecurity dashboard and committees that we have. These dashboards are part of our committees, especially the cybersecurity committee and other committees that we attend.
