Featured Reviews

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.

Real-time responses and reporting streamline vulnerability management
Qualys VMDR provides a real-time response and reporting feature, which is excellent. It allows us to see real-time graphs and reports for every asset, server, and more, which is very user-friendly. Our clients have given good feedback, and they are satisfied with the tool. We use it daily to fix vulnerabilities by connecting with infrastructure to remediate. The feedback from the client side is very 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."
"Qualys VM's best features are vulnerability management and customizable scoring."
"I like Qualys because it is a very complete product, more so than Tenable."
"It's a good product. After the scan our internet works well. It scans our security posture."
"The initial setup was good. We didn't have any problems with it."
"It's also highly customizable, allowing us to tailor it to our needs."
"The most valuable feature is the connection of threat intelligence information with identified vulnerabilities, which means you can prioritize vulnerabilities according to actual attacks."
"Detects new hosts along with vulnerabilities."
"It is a stable solution."
 

Cons

"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."
"I would like to have CSPM, a continuous scan-like cloud added to the solution."
"Qualys could be improved in its overall performance compared to other vulnerability management or scanning tools."
"They have integrated with other third parties, but it is still not viable."
"Improve the API speed."
"There needs to be better documentation."
"They're still evolving their platform in terms of reporting capabilities."
"We are moving away from Qualys to Defender ATP because I find that Defender ATP is much better at prioritizing the vulnerabilities that I should be looking at."
"Qualys VMDR identifies vulnerabilities and suggests fixes. However, it does not automate patching unless the patch management module is purchased separately."
 

Pricing and Cost Advice

"CoreOS Clair is open-source and free of charge."
"The license is on a yearly basis."
"The product is more expensive than that of any other vendor."
"The tool's pricing is expensive and I would rate the pricing a seven out of ten."
"The solution is expensive."
"There are no additional fees in addition to the standard licensing fees."
"Qualys VM is better suited for medium to large companies because the price can be too much for smaller customers."
"Usually every implementation is different and the quote is in function of number of assets."
"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."
