Sr Security Engineer at a tech vendor with 5,001-10,000 employees
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

"CSPM is currently the most used feature, and we are enjoying the new feature, FlexScan, which is valuable for Internet-facing VMs."
"Qualys TotalCloud is overall the best tool available in the market for scanning purposes."
"I would definitely recommend Qualys TotalCloud to other customers."
"Qualys TotalCloud's most valuable feature is its agent versatility."
"Its excellent graphical interface makes the scanning process simple."
"The agent and agentless scanning in TotalCloud, particularly the FlexScan method, is incredibly valuable. With traditional scanning approaches, we had to give IP ranges and whitelist IPs. All that is now simplified. FlexScan requires minimal intervention, and after configuration, it automatically collects data and performs necessary scans."
"I found the initial setup user-friendly."
"While automatic inventory detection upon connection is a helpful feature, a truly valuable capability would be assessing an environment's security posture against Azure and CIS best practices."
"Defender lets you orchestrate the roll-out from a single pane. Using the Azure portal, you can roll it out over all the servers covered by the entire subscription."
"Overall, Azure Security Center has greatly improved our company's security posture."
"The tool's most valuable feature is its support for cloud-native services like Kubernetes, containers, managed storage, and databases. Protecting these without Microsoft Defender for Cloud would be extremely challenging. For threat protection specifically, I find the signature-based detection and heuristic detection features very effective."
"The product has given us more insight into potential avenues for attack paths."
"DSPM is the most valuable feature."
"Most importantly, it's an integrated solution."
"I've seen benefits since implementing Microsoft Defender for Cloud. It's easy to manage for our large organization as an endpoint security solution. It integrates well with Office 365 and Windows 11, which is better than before. Patching, updates, and threat protection are all handled together now. Its AI features help predict threats."
"Defender is user-friendly and provides decent visibility into threats."
"Segmentation is the most powerful feature."
"Scalability-wise, I rate the solution a nine out of ten."
"Offers easy management with authentication and authorization features"
"I am impressed with the tool's visibility."
"The most beneficial security feature of the product revolves around the areas of vulnerability and configuration."
"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."
"The technical support is good."
 

Cons

"The cost of Qualys TotalCloud is high and could be more competitive."
"The response part of the Cloud Detection and Response (CDR) module can be improved."
"There is a lack of data segregation according to criticality or inventory."
"The onboarding process is a bit difficult. In the initial phase, it is very difficult to understand the features, what the dashboard contains, and what criteria they are using."
"Customer support with Qualys TotalCloud needs a little improvement with the response times."
"A feature improvement could be the inclusion of Windows OS support for container security, as it is currently only supported for Linux."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"Qualys TotalCloud's increasing complexity, due to the development and deployment of multiple solutions, is making the GUI difficult to navigate."
"The product was a bit complex to set up earlier, however, it is a bit streamlined now."
"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."
"Defender could provide more in-depth visibility into vulnerabilities and services. For instance, we wanted to scan Azure NetApp for sensitive data, but they didn't have that feature. It was only for storage accounts. I want Azure Defender features to cover all Azure resources rather than a few."
"When you work with it, the only problem that we're struggling with is that we have 21 different subscriptions we're trying to apply security to. It's impossible to keep everything organized."
"The overview provides you with good information, but if you want more details, there is a lot more customization to do, which requires knowledge of the other supporting solutions."
"Azure Security Center should be more easily understood by a non-technical person. It needs to be simplified and made more user-friendly for a non-technical person."
"I would rate Microsoft Defender for Cloud a six out of 10 due to its lack of necessary features to operate as a standalone solution."
"The product must improve its UI."
"The support and specifications need to be up to date for the cluster technologies"
"The deprecation of APIs is a concern since the deprecation of APIs will cause issues for us every time we upgrade."
"The testing process could be improved."
"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 solution's price could be better."
"Red Hat is somewhat expensive."
"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 TotalCloud offers cost-effective licensing flexibility."
"I am not sure about the pricing. From what I understand, it is a bit on the higher side, but I do not have the exact numbers."
"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"Its pricing is a little bit high in terms of Azure Security Center, but the good thing is that we don't need to maintain and deploy it. So, while the pricing is high, it is native to Azure which is why we prefer using this tool."
"Azure Defender is a bit pricey. The price could be lower."
"It has global licensing. It comes with multiple licenses since there are around 50,000 people (in our organization) who look at it."
"The solution is expensive, and I rate it a five to six out of ten."
"The licensing is straightforward but can become expensive if you cover everything. You must balance the cost against the importance of what needs covering."
"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."
"Currently, Microsoft offers only one plan at the enterprise level which is $15 per machine."
"It is bundled with our enterprise subscription, which makes it easy to go for it. It is available by default, and there is no extra cost for using the standard features."
"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."
"Red Hat offers two pricing options for their solution: a separate price, and a bundled price under the OpenShift Platform Plus."
"It's a costly solution"
