An operational system, similar to Linux where you can run your applications inside containers
With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers. When you mentioned using Nacula as part of your CI/CD pipeline, it means your application is deployed and managed automatically through the CI/CD process. Containers are used to deploy your application within this pipeline, but CoreOS does not run inside these containers. Instead, CoreOS is the base operating system that supports and manages these containers.

Continuous risk-based monitoring has strengthened incident response and vulnerability prioritization
I haven't explored Qualys VMDR's vulnerability lifecycle automation yet. One of my analysts mentioned that queries lack grouping operators in Qualys VMDR. From my experience, I would appreciate improvements in the query options in Qualys VMDR, specifically in the query-building process where I would need more features and operators. Additionally, we have been facing issues with Qualys on the cloud level. We cannot download the configuration profile from the cloud agent, and it is showing a pending action for download. During 2025, we noticed outages of Qualys a couple of times. I want to mention that there is an issue with receiving timely RCA deliveries. While this is not necessarily about the tool, it relates to support. The support has not been very responsive, and we are receiving RCAs a little delayed whenever we raise support cases or communicate with the TAMs. Additionally, the UI has a slight latency, which I and my team have experienced. They have also reported this latency issue when navigating through different pages.

Pros

"CoreOS Clair's best feature is detection accuracy."
"With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers."
"It is a simple solution that makes scanning easy. You just give it a scheduled task, and it will do everything for you."
"Qualys VMDR provides us with a quick response to threat findings through regular scheduled scanning, which improves our security operations."
"Monitors workstations and servers for vulnerabilities and creates reports."
"The vulnerability management feature is what I used the most. It is a good SaaS product. It is easy to use. It has a nice UI where you can see all the assets and vulnerabilities."
"There are fewer false positives when using this solution."
"Technical support is great and we've never really had a problem."
"It's very configurable to adjust impact to systems."
"I find Qualys VM very robust, and it's very useful for vulnerability management and patch management. The value that it brings to my environment is economies of scale. There is no limitation on adding any endpoints. You go by the rule, and it's added once another endpoint is added to our environment. It's automatically installed, and it's less work from our end. It frees up my license automatically if I don't need an endpoint or if my machine is decommissioned. I like the dashboard displays because I don't see any duplication. The most important part is vulnerability management and prioritization. Unlike Symantec, it shows the kind of vulnerability I would want to patch first. It provides a holistic view of the kind of vulnerabilities and the ones I should remediate first. I don't have to do a scan; it just brings up those critical kinds of vulnerabilities like zero-day vulnerabilities and tells me to prioritize them. You have to prioritize these vulnerabilities first and go on with the rest. The dashboard shows me the ones that have been fixed, so I don't have to complete an aging report. The user experience and the graphical interface are good. As it's user-friendly and understandable on an executive level, it brings real value. We also use this solution because it's robust and flexibile."
 

Cons

"It can be improved in its support response. They usually take up to seven days to resolve the issue."
"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"The response time of technical support takes a while."
"Integration could be better. When you think about scanning, it's not used just with this product alone but with other Qualys products. If you think about the bundle, the product itself is good. But integration with other products and packages has space for improvement. They should also offer a better price for bundles."
"Qualys could be improved in its overall performance compared to other vulnerability management or scanning tools."
"Some of the older features could be polished instead of focusing on releasing new features."
"The IoT scan is not great."
"Certain integration factors between different options could be improved."
"The reporting and dashboards could improve in Qualys VM. However, they have improved since the previous versions."
"The price could be better. Asset view is still a legacy feature. I'm not able to extract the information about the asset with complete details. It would be better if they fixed that in the next release. I know Qualys is already working on it, so I'm hopeful it will be available in the next five or six months. That would be something that's changed where I seek improvement."
 

Pricing and Cost Advice

"CoreOS Clair is open-source and free of charge."
"It is more expensive than other products on the market."
"Qualys is cheaper and more affordable than other solutions."
"The tool's pricing is expensive and I would rate the pricing a seven out of ten."
"An annual license for a single scanner costs around $3,000."
"It is a high cost product. Compared to the other solutions, it is around 15 to 20% higher in cost."
"We do see over $100,000 in terms of price, for mid-size programs. You likely will pay more than $100,000 without any discount. It is a bit pricey."
"The product is more expensive than that of any other vendor."
"In Nigerian Naira, we spend about roughly four to five million to use this solution and this is expensive compared to solutions like Nessus."
