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

"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."
"I like the web API security and IoT scanning features the most. The user-friendly design of TotalCloud's interface enables customers to navigate it and use its full potential easily"
"The scalability is good as well. I would rate it ten out of ten."
"Qualys TotalCloud has great accuracy and reliability, as it is a very complete program with tools that help experts understand the vulnerabilities of today."
"Qualys TotalCloud has helped us view our risk structure, vulnerabilities, and security posture."
"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."
"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."
"We were able to realize its benefits within 24 to 48 hours."
"It has improved our security posture a lot, and with the implementation of Azure Security Center, we have resolved many issues, including being able to do security monitoring of the complete infrastructure across both cloud and on-prem environments."
"It alerts us to our vulnerabilities and ensures compliance by marking off a compliance tool checklist."
"One of the features that I like about the solution is it is both a hybrid cloud and also multi-cloud. We never know what company we're going to buy, and therefore we are ready to go. If they have GCP or AWS, we have support for that as well. It offers a single-panel blast across multiple clouds."
"The most valuable feature is that it's intuitive. It's very intuitive."
"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."
"It offers virus management and addresses threats such as viruses, worms, spyware, and other critical security concerns."
"I would like to see more connectors and plugins with other platforms."
"Microsoft Defender for Cloud has improved our security poster by at least 100 percent."
"Scalability-wise, I rate the solution a nine out of ten."
"The technical support is good."
"The most valuable feature of the solution is its monitoring feature."
"Offers easy management with authentication and authorization features"
"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."
"The most beneficial security feature of the product revolves around the areas of vulnerability and configuration."
"The most valuable feature is the ability to share resources."
 

Cons

"In terms of improvement, remediation still belongs to the cloud team, which is one of the issues we faced with Qualys TotalCloud."
"The price is very expensive, actually."
"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."
"Regarding improvements to Qualys TotalCloud, I suggest that user navigation can be enhanced because initially, many users found it complicated and had trouble understanding the platform due to information being spread across multiple tabs."
"There is room for improvement in the support."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"The improvement needed in Qualys TotalCloud is mainly in the artificial intelligence automation agents, where we can customize and create what meets our needs, not necessarily having to use those provided in the tool."
"Their support could be improved."
"They could always work to make the pricing a bit lower."
"I don't appreciate Microsoft Defender for Cloud because it seems to interfere with many things. That's the problem I've been experiencing with it."
"It's hard to reach someone who understands my problems. I haven't had many issues, so I haven't called them."
"The product was a bit complex to set up earlier, however, it is a bit streamlined now."
"Defender for Cloud is pretty costly for a single line. It's incredibly high to pay monthly for security per server."
"Defender is occasionally unreliable. It isn't 100% efficient in terms of antivirus detection, but it isn't an issue most of the time. It's also somewhat difficult to train new security analysts to use Defender."
"For Kubernetes, I was using Azure Kubernetes Service (AKS). To see that whatever is getting deployed into AKS goes through the correct checks and balances in terms of affinities and other similar aspects and follows all the policies, we had to use a product called Stackrox. At a granular level, the built-in policies were good for Kubernetes, but to protect our containers from a coding point of view, we had to use a few other products. For example, from a programming point of view, we were using Checkmarx for static code analysis. For CIS compliance, there are no CIS benchmarks for AKS. So, we had to use other plugins to see that the CIS benchmarks are compliant. There are CIS benchmarks for Kubernetes on AWS and GCP, but there are no CIS benchmarks for AKS. So, Azure Security Center fell short from the regulatory compliance point of view, and we had to use one more product. We ended up with two different dashboards. We had Azure Security Center, and we had Stackrox that had its own dashboard. The operations team and the security team had to look at two dashboards, and they couldn't get an integrated piece. That's a drawback of Azure Security Center. Azure Security Center should provide APIs so that we can integrate its dashboard within other enterprise dashboards, such as the PowerBI dashboard. We couldn't get through these aspects, and we ended up giving Reader security permission to too many people, which was okay to some extent, but when we had to administer the users for the Stackrox portal and Azure Security Center, it became painful."
"I would suggest building a single product that addresses endpoint server protection, attack surface, and everything else in one solution. That is the main disadvantage with the product. If we are incorporating some features, we end up in a situation where this solution is for the server, and that one is for the client, or this is for identity, and that is for our application. They're not bundling it. Commercially, we can charge for different licenses, but on the implementation side, it's tough to help our end-customer understand which product they're getting."
"The solution's visibility and vulnerability prevention should be improved."
"The tool's command line and configuration are hard for us to understand and make deployment complex. It should also include zero trust, access control features and database connectivity."
"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 initial setup is pretty complex. There's a learning curve, and its cost varies across different environments. It's difficult."
"The testing process could be improved."
"The solution's price could be better."
"The solution lacks features when compared to some of the competitors such as Prisma Cloud by Palo Alto Networks and has room for improvement."
"Red Hat is somewhat expensive."
 

Pricing and Cost Advice

"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."
"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 is cost-efficient and was selected for its value compared to other products."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"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."
"Its price seems higher compared to other tools, but it is worth it. If they could adjust the pricing and make it comparable with other tools, that would be great."
"The pricing is very difficult because every type of Defender for Cloud has its own metrics and pricing. If you have Cloud for Key Vault, the pricing is different than it is for storage. Every type has its own pricing list and rules."
"The cost of the license is based on the subscriptions that you have."
"We only use the free tier, so we haven't faced any pricing, setup costs, or licensing challenges."
"Pricing is difficult because each license has its own metrics and cost."
"This is a worldwide service and depending on the country, there will be different prices."
"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."
"Defender for Cloud is pretty costly for a single line. It's incredibly high to pay monthly for security per server. The cost is considerable for an enterprise with 500-plus virtual machines, and the monthly bill can spike."
"Azure Defender is definitely pricey, but their competitors cost about the same. For example, a Palo Alto solution is the same price per endpoint, but the ground strikes cost a bit more than Azure Defender. Still, it's pricey for a company like ours. Maybe well-established organizations can afford it, but it might be too costly for a startup."
"The price of Red Hat Advanced Cluster Security for Kubernetes is better than Palo Alto Prisma."
"It's a costly solution"
"We purchase a yearly basis license for the solution."
"Red Hat offers two pricing options for their solution: a separate price, and a bundled price under the OpenShift Platform Plus."
"The pricing model is moderate, meaning it is not very expensive."
