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.

Pros

"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."
"CoreOS Clair's best feature is detection accuracy."
"The most valuable feature is automation."
"The platform's most valuable features include its robust vulnerability detection capabilities and automated remediation workflows."
"Qualys VM is very stable."
"The product's patch management is excellent for keeping our critical servers and third-party applications updated efficiently."
"The most valuable feature is the ability to run different capabilities with the same agent. With only one agent, we can have EDR, vulnerability management, compliance and some basic SaaS security capabilities."
"It allowed us to divide tasks easily among teammates, significantly improving efficiency."
"The initial setup was good. We didn't have any problems with it."
"I like the automated report generation and vulnerability report generation."
 

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."
"There needs to be better documentation."
"In terms of improvement for the web application console, in the older version, things were more segregated and presented in a brief format."
"It would be nice to have an all-in-one solution that was automated and could handle the scanning and reports as well as the patching and updating."
"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."
"It would be helpful to have features for better tracking, including options for adding relevant owners or supporting groups for each asset."
"Improve the API speed."
"The response time of technical support takes a while."
"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."
 

Pricing and Cost Advice

"CoreOS Clair is open-source and free of charge."
"The solution is reasonably priced for the value it provides."
"The tool's pricing is expensive and I would rate the pricing a seven out of ten."
"They have recently changed the pricing model, which is now better than it was before."
"Usually every implementation is different and the quote is in function of number of assets."
"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."
"An annual license for a single scanner costs around $3,000."
"We have an annual contract for Qualys VMDR. I believe it's for either two years or five years."
"It's very expensive, especially if you want to use multiple modules of Qualys."
