Risk-based triage has transformed container security and now prioritizes high-impact threats
The best features Qualys TotalCloud offers currently include managing cloud infrastructure and container security while facing major challenges such as alert fatigue. Traditional vulnerability scanners flag hundreds of CVEs on short-lived Kubernetes containers, some of which have no internet exposure or are gone before we can even triage them. I leverage Qualys TotalCloud to move beyond static CVSS. I use it to implement runtime exposure, correlation risk reprioritization, and shift-left integration. This notifies developers to fix a base image upstream rather than patching live ephemeral instances. In my work with cloud and container security, the biggest operational hurdle was alert fatigue. I use Qualys to shift left from static CVSS severity to context-aware risk prioritization. I correlated raw vulnerability data with real-time risk factors such as public network exposure, active runtime execution, or overly permissive IAM roles. This allows us to immediately drop the priority of isolated containers and escalate lower-severity CVEs that sit on an exposed, high-risk path. We can map these findings directly back to our CI/CD pipelines so developers can patch the root base images upstream. We have drastically cut down the signal-to-noise ratio, saved a lot of manual hours doing triage work, and ensured engineering effort goes directly towards high-impact risk reduction.

Cloud security has cut investigation time and now reveals threats faster but needs simpler oversight
When deploying AI applications, my key security concerns with Microsoft Defender for Cloud are data loss, leakage of data, and guardrails around the actual AI, and I am hoping that this is going to help me put those guardrails in place and identify data exfiltration. Microsoft Defender for Cloud has not helped me manage and secure multi-cloud environments, as we are 100 percent Microsoft and have not really got it in any other environment at all. I am not yet using the unified AI-powered security feature offered by Microsoft Defender for Cloud, but that is coming. I am not yet using the integrated XDR feature of Microsoft Defender for Cloud, but that is coming. I am not yet utilizing the GenAI threat protection features of Microsoft Defender for Cloud. That is also coming and a lot of that will come from learning it here. I have enabled the agentless scanning in my cloud environment with Microsoft Defender for Cloud. Assessing the impact on my workload protection without needing to install agents with Microsoft Defender for Cloud makes it a lot easier, but it also identifies a lot more, which puts more load on me sometimes. I would advise another organization considering Microsoft Defender for Cloud that it is the most logical route to follow if their whole ecosystem is Microsoft. It is easy to implement and it is very self-explanatory when doing it, making sense to just follow the steps as it is too simple, really. I would rate this review a 7.5 out of 10.

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

"I highly recommend Qualys TotalCloud to other users."
"Qualys TotalCloud's most valuable feature is its agent versatility."
"CSPM is currently the most used feature, and we are enjoying the new feature, FlexScan, which is valuable for Internet-facing VMs."
"The most valuable feature is extensibility."
"One of the features I appreciate is the ability to generate daily reports without relying on anyone else."
"Qualys TotalCloud helps you not just to identify misconfigurations, but you can actually also fix issues."
"Qualys TotalCloud has significantly improved our organization by automating our reporting processes, reducing the time spent on report creation from two hours to less than fifteen to twenty minutes."
"Qualys TotalCloud provides unified vulnerability and threat assessment for IaaS and SaaS and a single prioritized view of risk, which helps reduce my workload by not having to combine multiple sources."
"Defender for Cloud is a plug-and-play solution that provides continuous posture management once enabled."
"The most valuable features are the monitoring of users, endpoint detection and response, and the adaptability of the AI threat intelligence engine, which quickly adapts to customizations."
"There is no better tool found to protect workloads in Azure than Microsoft Defender for Cloud."
"Compared to other products, Azure Defender's main advantage is native integration with all Azure services."
"I find Microsoft Defender for Cloud's KQL very flexible and powerful. It's really easy to search through with KQL queries to find the security breaches and incidents and to track down the breach itself."
"The security policy is the most valuable feature for us. We can go into the environment settings and attach any globally recognized framework like ISO or any benchmark."
"Microsoft Defender for Cloud can find potential phishing links and malicious code in data at rest."
"It helps you to identify the gaps in your solution and remediate them, and it produces a compliance checklist against known standards such as ISO 27001, HIPAA, iTrust, etc."
"I like virtualization and all those tools that come with OpenShift. I also like Advanced Cluster Management and the built-in security."
"One of the most valuable features I found was the ability of this solution to map the network and show you the communication between your containers and your different nodes."
"Scalability-wise, I rate the solution a nine out of ten."
"The technical support is good."
"Offers easy management with authentication and authorization features"
"I am impressed with the tool's visibility."
"Segmentation is the most powerful feature."
"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."
 

Cons

"In terms of improvement, remediation still belongs to the cloud team, which is one of the issues we faced with Qualys TotalCloud."
"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."
"Overall, we are satisfied with it. However, the response part of the Cloud Detection and Response (CDR) module can be improved. It is not yet in place according to requirements; it is not completely available even though the module has been released."
"The areas in the solution that have room for improvement include the UI/UX design, which should be improved, and they should integrate more artificial intelligence into the product."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"One thing that could be improved is the user experience and navigation."
"One of the things that could be improved is the alerts. Qualys is a fantastic tool, especially with the TruRisk feature, but one challenge that most leaders face involves alert fatigue."
"The patching process with Qualys Patch Management, which is part of TotalCloud, does not cover installing certain prerequisites on the servers or workstations. This shortcoming means we must rely on SCCM when any service stack updates or additional prerequisites are needed."
"Comparing Microsoft Defender for Cloud to other solutions on the market, Microsoft needs to push a little bit to improve it."
"Microsoft Defender could be more centralized. For example, I still need to go to another console to do policy management."
"Sometimes it's very difficult to determine when I need Microsoft Defender for Cloud for a special resource group or a special kind of product."
"Microsoft Defender for Cloud can be improved because many of the functions involve multiple places to accomplish the same task, which can make it convoluted."
"The product was a bit complex to set up earlier, however, it is a bit streamlined now."
"Another thing that could be improved was that they could recommend processes on how to react to alerts, or recommend best practices based on how other organizations do things if they receive an alert about XYZ."
"Microsoft can improve the pricing by offering a plan that is more cost-effective for small and medium organizations."
"Azure's system could be more on point like AWS support. For example, if I have an issue with AWS, I create a support ticket, then I get a call or a message. With Azure support, you raise a ticket, and somebody calls back depending on their availability and the priority, which might not align with your business priority."
"The initial setup is pretty complex. There's a learning curve, and its cost varies across different environments. It's difficult."
"Red Hat is somewhat expensive."
"The solution's visibility and vulnerability prevention should be improved."
"The solution's price could be better."
"The testing process could be improved."
"The deprecation of APIs is a concern since the deprecation of APIs will cause issues for us every time we upgrade."
"The documentation about Red Hat Advanced Cluster Security available online is very limited... So it's very limited to the documentation."
"The support and specifications need to be up to date for the cluster technologies"
 

Pricing and Cost Advice

"Although Qualys TotalCloud is relatively expensive due to its unique automation features, its cost-effectiveness is rated an eight out of ten, with ten being the most costly."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"The cost is high, but it meets our organizational needs."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"Although I am outside of the discussion on budget and costing, I can say that the importance of security provided by this solution is of such importance that whatever the cost is, it is not a factor."
"There are improvements that have to be made to the licensing. Currently, for servers, it has to be done by grouping the servers on a single subscription... We don't have an option whereby, if all those resources are in one subscription, we can have each of the individual servers subject to different planning."
"The pricing and licensing of Microsoft Defender for Cloud have been good for us. We appreciate the licensing approach based on employee count rather than a big enterprise license."
