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.

Offers easy management and container connection with HTTPS, but the support needs to improve
I have experience with the solution's setup in Rio de Janeiro, Brazil and our company has assisted in the development of a cluster in a research department, but we didn't start from scratch because we have IT professionals who have installed Kubernetes across 12 nodes of a cluster and a new environment can be created for a new platform. I also had another setup experience of Red Hat Advanced Cluster Security for Kubernetes in Portugal where I had to implement the solution in a cluster of 22 computer servers, which was completed with assistance from the IT department of the company. The initial setup process of the solution can be considered as difficult. The setup process involves using the permissions, subnets and range of IPs, which makes it complex. Deploying Red Hat Advanced Cluster Security for Kubernetes takes around eight to ten hours for new clusters. The solution's deployment can be divided into three parts. The first part involves OpenStack, where the cluster's resources need to be identified. The second part involves virtualizing assets and identifying other physical assets, for which OpenStack, Kubernetes, or OpenShift are used. The third part of the deployment involves dividing the networks into subnetworks and implementing automation to deploy the microservices using Helm. The number of professionals required for the solution's deployment depends upon the presence of automated scripts. Ideally, two or three professionals are required to set up Red Hat Advanced Cluster Security for Kubernetes.

Quotes from Members

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

Pros

"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."
"The integrations for this solution are very good. I use a different product for virtual patching of vulnerabilities and Qualys integrates well with that product."
"The solution shows us classic categories, including high, medium, and low risks. It also shows critical items, and that gives us the advantage of prioritizing things."
"The most valuable feature is that this solution is very lightweight."
"It's very configurable to adjust impact to systems."
"It gives a very good overview of the inventory assessment process, and it can be accessed across our company because it's a global tool."
"Qualys VM is very stable."
"I value the scheduling of scans and reports as per the desired timeframes."
"I am impressed with the tool's visibility."
"It is easy to install and manage."
"I like virtualization and all those tools that come with OpenShift. I also like Advanced Cluster Management and the built-in security."
"Offers easy management with authentication and authorization features"
"The benefit of working with the solution is the fact that it's very straightforward...It is a perfectly stable product since the details are very accurate."
"Scalability-wise, I rate the solution a nine out of ten."
"The most valuable feature is the ability to share resources."
"The most beneficial security feature of the product revolves around the areas of vulnerability and configuration."
 

Cons

"Qualys VM's vulnerability scan could be improved, especially the number of CVE numbers it can manage at a time."
"The ability to manage user accounts and give rights to the operator to know about abnormalities of applications is something that needs improvement."
"Qualys VM could improve by having more skilled support personnel."
"Improve the API speed."
"Could use additional security for the app."
"The customer support is very bad."
"It's quite complex on the way it is set up, so it takes a fair bit of time in order to get your head around it in order to deploy it. Once you've deployed it, then you're never confident on the versions of the browsers and the SSL certificates, etc. You have to always go back into Qualys and check."
"There seems to be a lack of easy onboarding into Qualys."
"The documentation about Red Hat Advanced Cluster Security available online is very limited... So it's very limited to the documentation."
"I do see that some features associated with the IAST part are not included in the tool, making it an area where improvements are required."
"The support and specifications need to be up to date for the cluster technologies"
"Red Hat is somewhat expensive."
"The deprecation of APIs is a concern since the deprecation of APIs will cause issues for us every time we upgrade."
"They're trying to convert it to the platform as a source. They are moving in the direction of Cloud Foundry so it can be easier for a developer to deploy it."
"The solution's visibility and vulnerability prevention should be improved."
"The initial setup is pretty complex. There's a learning curve, and its cost varies across different environments. It's difficult."
 

Pricing and Cost Advice

"Qualys Virtual Scanner Appliance isn't expensive right now. But the price for their product bundles could be better."
"The license is on a yearly basis."
"We have an annual contract for Qualys VMDR. I believe it's for either two years or five years."
"Qualys VM is reasonably priced."
"It is more expensive than other products on the market."
"The tool's pricing is expensive and I would rate the pricing a seven out of ten."
"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."
"The pricing model is moderate, meaning it is not very expensive."
"We purchase a yearly basis license for the solution."
"The price of Red Hat Advanced Cluster Security for Kubernetes is better than Palo Alto Prisma."
"It's a costly solution"
"Red Hat offers two pricing options for their solution: a separate price, and a bundled price under the OpenShift Platform Plus."
