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.

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.

Centralized cluster management has improved daily operations and simplifies troubleshooting
I am happy with SUSE Rancher, but there are a few areas where it could be improved. During major version upgrades, the process can become a bit complex, especially in air-gapped environments where image management and dependencies require extra planning. Additionally, troubleshooting sometimes still requires switching to the command line because not every error is visible in the UI. If the UI provided more detailed diagnostic and troubleshooting information, it would make our issue resolution even faster. Other than that, it has been a reliable platform for all of us. I think the documentation is already very good, but for complex scenarios such as air-gapped environments, disaster recovery, or multi-cluster upgrades, having more step-by-step examples and troubleshooting guides would be very helpful. On the UI side, if SUSE Rancher could provide more detailed error messages and built-in diagnostic recognition, it would reduce the need to switch to logs and command lines. Those improvements would make our daily operations even easier and smoother, especially for new administrators and fresh team members.

Quotes from Members

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

Pros

"I appreciate TotalCloud's real-time protection and remediation features. The remediation options include automated one-click remedies and custom changes that help manage vulnerabilities efficiently."
"Qualys TotalCloud has helped us view our risk structure, vulnerabilities, and security posture."
"Vulnerability and threat detection and assessment of the criticality of the vulnerabilities exposed are most valuable."
"CSPM is currently the most used feature, and we are enjoying the new feature, FlexScan, which is valuable for Internet-facing VMs."
"I would definitely recommend Qualys TotalCloud to other users."
"The ability to identify cloud misconfigurations, prioritize security risks, and monitor cloud resources from a single platform is quite valuable."
"My experience with using TruRisk to mitigate noise from raw CVEs has been great."
"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."
"The most beneficial security feature of the product revolves around the areas of vulnerability and configuration."
"The most valuable feature of the solution is its monitoring feature."
"Segmentation is the most powerful feature."
"The technical support is good."
"It is easy to install and manage."
"Offers easy management with authentication and authorization features"
"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 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."
"SUSE Rancher has positively impacted my organization as productivity is the main point, and the productivity has improved because the main project goal was to finish the project faster, which was particularly important since we have many applications."
"SUSE Rancher helps me manage and automate processes with Kubernetes through full integration from hardware to application."
"The end-to-end deployment was at least 30 percent cheaper than OpenShift, which was the biggest criterion since customers are cost-conscious."
"SUSE Rancher has made things easier for my team and organization by reducing errors, as I use it every day of the week, and it shows us issues through dashboards."
"I could say that with SUSE Rancher, we've managed to cut the provisioning time to probably one-tenth of the usual provisioning time."
"SUSE Rancher has positively impacted my organization with increased efficiency in a 10x manner."
"The most valuable features of SUSE Rancher include the user interface and the display features."
"With SUSE Rancher, everything is in one place and centralized, daily operations are much faster and easier for us, it has reduced manual efforts and helped us troubleshoot issues faster because we get a single view from all our clusters, and overall, it has improved our team efficiency and consistency."
 

Cons

"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."
"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."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"Qualys TotalCloud has the potential to improve by integrating a hybrid platform for comprehensive management of both on-premises and cloud infrastructures."
"I think Qualys TotalCloud needs to improve its handling of zero-day vulnerabilities and supply chain management because modern ransomware attacks not only target prime critical infrastructures but also the supply chain system."
"In my opinion, the combination of detection and protection features in Qualys TotalCloud cannot protect but can only detect."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"The price is very expensive, actually."
"Red Hat is somewhat expensive."
"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 price could be better."
"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 testing process could be improved."
"The support and specifications need to be up to date for the cluster technologies"
"The initial setup is pretty complex. There's a learning curve, and its cost varies across different environments. It's difficult."
"The deprecation of APIs is a concern since the deprecation of APIs will cause issues for us every time we upgrade."
"All the tasks that SUSE Rancher does can be done in alternative methods, so it is not a must-have or a necessary tool in my view."
"Regarding the platform's features and advantages, it is unfortunate that observability and some artificial intelligence functionality work fully only with a paid subscription."
"I wish the container could be more lightweight so that anyone can test and verify SUSE Rancher Prime."
"Some initial setup and configuration were required by the admin side for enabling security policies, which were not supported initially."
"Additional features for a paid solution should be included, such as more detailed insights, better graphics, and an improved user interface."
"I have noticed that SUSE Rancher's GUI is slow because we have more than 1,000 pods, and when searching for a pod name, the page takes some time to load."
"There are a lot of issues in the tool, such as addressing the errors, addressing the stability, and addressing the reliability."
"One of the major challenges I faced with SUSE Rancher was during a POC for one customer who was using VMware; there was a significant challenge between VMware CSI and SUSE integrations."
