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.

Reduces vulnerability exposure time and automates workflow for efficient security management
One area where Qualys VMDR can be improved is the missing feature for deploying agents for over 1,000 assets, as we need to do it manually. Qualys doesn't have its own tool to deploy the agents all at once, so we need to use third-party tools such as BigFix or something else to deploy the agents, which is my main concern and should be fixed by the Qualys team. That is the main thing I would like to see changed, and apart from that, everything is good.

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."
"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's really beneficial for scanning and interacting with the agent."
"The reporting functionality is great."
"Qualys VM had a recent upgrade and the newer version is supporting the cloud."
"It gives you a lot of options, and it integrates with our ServiceNow for ticketing and all."
"It's also highly customizable, allowing us to tailor it to our needs."
"The initial setup was good. We didn't have any problems with it."
"It is quite easy to implement."
"I value the scheduling of scans and reports as per the desired timeframes."
 

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 reporting and dashboards could improve in Qualys VM. However, they have improved since the previous versions."
"Qualys VMDR could improve in reducing the occurrences of false positive vulnerabilities."
"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."
"It is a struggle to be able to pull our report and to be able to do onboarding using automated tools."
"There's a need to upgrade or fix the potential vulnerability rate. Around 20,000 potential vulnerabilities were showing in Qualys VMDR, but none of the other tools showed them. When we checked, it wasn't the case. Support explained that even small issues were being counted as vulnerabilities, causing issues in our audit. So, the security features could be improved to identify vulnerabilities accurately."
"The disadvantage of working with Qualys is that the graphical interface is quite outdated."
"I would like to have CSPM, a continuous scan-like cloud added to the solution."
"Sometimes the scanning can get overwhelmed and start to drag when a lot of users are trying to scan at once."
 

Pricing and Cost Advice

"CoreOS Clair is open-source and free of charge."
"The solution is reasonably priced for the value it provides."
"The solution is expensive."
"The tool's pricing is expensive and I would rate the pricing a seven out of ten."
"The product is more expensive than that of any other vendor."
"It is a high cost product. Compared to the other solutions, it is around 15 to 20% higher in cost."
"Qualys VM is quite expensive. It's a subscription-based license, and it's yearly. Right now, it's open for me, and I don't have any limitations or caps on the licenses. They are seeing if the product is viable for 4500 users. I can add as much as I want, and at the end of the subscription, they'll let me know how many licenses were actually used and bill me accordingly. On a scale from one to five, I would give their pricing a three. It's still expensive."
"The pricing is very competitive."
"The license is on a yearly basis."
