Felipe Giffu - PeerSpot reviewer

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"CoreOS Clair's best feature is detection accuracy."
"CoreOS Clair can be used by organizations of any size."
"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."
"Qualys VMDR has positively impacted my organization by reducing vulnerability exposure time through faster detection and patching, and it has improved compliance reporting with accurate and up-to-date data."
"With QualsyGuard we have been able to achieve this by utilizing its modules, such as vulnerability management, policy compliance, web scanning, malware detection, and asset tagging."
"It's been the chosen solution year after year for vulnerability management and our vulnerability management program is centered around this tool."
"This is one of the best products I have worked with so far. I like the power of Qualys, and it's a better solution because you can scan a compact file, a BIT file, or batch files. The product already knows what's happening inside, and you don't need to expand the package. Tenable will do the same thing, but you need to have a package issuance claim. With Qualys, we can immediately understand the file, even a compact file. If there's some kind of discovery or incident, you will know what happened in the environment."
"Qualys help identifies the weakness in our critical infrastructure and provides guidelines how to address them."
"Vulnerability scans are easily managed and maintained using Qualys."
"Qualys VM's best features are vulnerability management and customizable scoring."
"Using this product, we now have a vulnerability management cycle wherein VMDR plays a major role."
 

Cons

"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"It can be improved in its support response. They usually take up to seven days to resolve the issue."
"There are scenarios where a vulnerability is reported once yet not in subsequent scans, even if we have not fixed it."
"The reporting and dashboards could improve in Qualys VM. However, they have improved since the previous versions."
"Improve the API speed."
"There needs to be better documentation. Maybe their price scheduler could be made simpler. It's expensive."
"Qualys currently does not have any features for scanning SCADA, IoT, and Industrial Control Systems."
"Sometimes the scanning can get overwhelmed and start to drag when a lot of users are trying to scan at once."
"Qualys Container Security can improve the interface. It could be easier to navigate and be enriched."
"Reports were lacking somewhat on the customization side."
 

Pricing and Cost Advice

"CoreOS Clair is open-source and free of charge."
"It is a high cost product. Compared to the other solutions, it is around 15 to 20% higher in cost."
"The pricing and licensing for Qualys could be improved."
"I used to work there, so I never paid for the product. As an employee, we get a lifetime license for personal use, and that's what I'm using. It is a comprehensive platform, so there is a lot more to it. There could be other solutions that are probably a little bit cheaper, but it depends on what people need. Different people have different needs. It offers many things on the same platform. If you add all the things up, it should be cheaper, but I have not done any analysis specifically."
"Qualys VM is reasonably priced."
"In Nigerian Naira, we spend about roughly four to five million to use this solution and this is expensive compared to solutions like Nessus."
"Usually every implementation is different and the quote is in function of number of assets."
"Qualys is cheaper and more affordable than other solutions."
"We have an annual contract for Qualys VMDR. I believe it's for either two years or five years."
