Room For Improvement

Windows Server Update Services requires UI enhancements, better integration, stability improvements, and efficient patch management for smoother operation.

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

IT Manager at Handi Quilter, Inc.

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

Features enhancing the interaction with IT or security teams should be added, such as a ticketing feature that, if an issue arises in the CSAM module, enables direct ticket creation in systems like ServiceNow.

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.

I find that while information is available regarding which users have access to our servers, retrieving it often requires checking servers individually rather than obtaining a consolidated extraction when needed.

Centralized updates have simplified patch management and have ensured timely security compliance

I am not sure about Windows Service Update; I mentioned Windows Server, but I do not think we do Windows Server AppFabric. I indicated that we do not use Windows Process Activation Services or Windows Server Failover Clustering. I acknowledge that Update Services is what I meant to communicate. We have a procedure related to the automatic update approval feature in Microsoft Windows Server Update Services. I do not know if we used this procedure; we just use Microsoft Windows Server Update Services with a scheduled task, and that is all. I have not used the reporting and inventory capabilities to manage update compliance, but maybe our security team has. I like this product because there is no other product, and my colleague is working on the Azure service updates, so if that is working, then we have no need to use Microsoft Windows Server Update Services from Windows anymore. I have not found something that I have been using the most.

Centralized asset management has supported real-time risk tracking across massive inventories

Qualys CyberSecurity Asset Management is good enough to differentiate different kinds of assets, whether applications, computers, or servers. There are categories to differentiate all of them, making it easier to manage this kind of infrastructure. One thing that I particularly liked about Qualys CyberSecurity Asset Management is that it has a very broad classification of different kinds of assets, which is very helpful to manage. The ticketing functionality that it has to manage all these kinds of infrastructure makes it easier to work on different kinds of problems that these large inventories face. It is mostly scalable and quite a good option. The inventory count was really huge, and doing it manually or using other options would have been difficult. We considered ServiceNow at that time, which was a good option. However, having real-time scanning and all those things in one single solution makes Qualys always the best option. Getting different kinds of modules and inventory in one solution is good enough. TruRisk scoring was enabled, and we had integrated ServiceNow with Qualys. All findings from Qualys used to go into ServiceNow, where we had our own scoring system. For example, if an asset is critical to the organization and has a risk scoring as critical but is also exposed to the internet, we would have two different kinds of risk scores. We did not consider directly using the Qualys TruRisk score but instead used custom scores of our own, which worked well enough. I deployed a few Cloud Agents on both Linux and Windows machines for scanning purposes. It was a cloud-based SaaS solution.
