Qualys CyberSecurity Asset Management struggles with integration, configuration flexibility, tagging accuracy, and performance issues needing improvement.

The inventory tool and the entire backend of Microsoft Windows Server Update Services is poorly coded. It's not very reliable, so you can tell when dealing with bad code, and it may work one day but may not work another.

Nadeem Nasir

I would like the updates to be less often and more rarely because they have a high impact on our team.

Has supported routine update requests and maintained reliable system operations

Senior Oracle DBA at a financial services firm with 11-50 employees

I think that the most valuable feature of Microsoft Windows Server Update Services is the update for Microsoft Windows Server, as we do not use any other tools, but I don't know if Office 365 is under Windows update services regulation; it is not in our domain because we use it, but other teams are responsible for this task. The key features or benefits of Microsoft Windows Server Update Services that have been most valuable in my IT administration processes are just the services for updating my Windows and Windows Servers, and as I mentioned, we don't use many applications; we just use it for Windows updates. Microsoft Windows Server Update Services supports our regular requests for reliable systems, and updates are part of the process of keeping those systems stable, reliable, and confidential.

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.
