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

"Qualys TotalCloud fulfills all these needs."
"One of the features I appreciate is the ability to generate daily reports without relying on anyone else."
"The most valuable feature is extensibility."
"In my opinion, this is the best tool."
"The most valuable feature of Qualys TotalCloud is the visibility it provides."
"I appreciate Qualys TotalCloud's ability to onboard any type of device with ease, including containers."
"If I had to say something positive about the product that brings me the biggest benefit, I would say it has accurate reports, gets new update CVEs, zero-day attack detection, and is easy to manage with its GUI."
"The most valuable feature is the ability to share resources."
"The most valuable feature of the solution is its monitoring feature."
"The most beneficial security feature of the product revolves around the areas of vulnerability and configuration."
"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."
"Segmentation is the most powerful feature."
"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."
"It is easy to install and manage."
"I could say that with SUSE Rancher, we've managed to cut the provisioning time to probably one-tenth of the usual provisioning time."
"The most valuable features of SUSE Rancher include the user interface and the display features."
"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."
"The end-to-end deployment was at least 30 percent cheaper than OpenShift, which was the biggest criterion since customers are cost-conscious."
"Rancher Desktop provides support for Kubernetes setup on local machines."
"SUSE Rancher has positively impacted my organization by making the teams' work easier and reducing project delivery time."
"We have been able to cut down the amount of time an expert needs to spend on upgrade and maintenance to a fifth of what it was before."
"SUSE Rancher is best used for large-scale applications such as ours; it manages very high-end infrastructure, and it has very good customer support, and it is very easy to understand in terms of usage."
 

Cons

"TotalCloud could improve its scanning of niche devices like Wi-Fi dongles and USB modems because they are often untested. It covers everything else, like laptops, mobile devices, and Bluetooth IoT devices. They can improve on the small IoT devices because hackers and testers use these."
"Qualys TotalCloud has the potential to improve by integrating a hybrid platform for comprehensive management of both on-premises and cloud infrastructures."
"Regarding technical support from Qualys, they respond, but the response time can be too long. Sometimes we need to wait weeks for solutions to simple questions."
"There is room for improvement in vulnerability scanning, particularly for PaaS environments. Currently, Qualys does not have full access to these instances, which limits its effectiveness."
"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."
"Although TotalCloud is a helpful tool, some of its advanced features are still under development."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"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."
"The support and specifications need to be up to date for the cluster technologies"
"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."
"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."
"Red Hat is somewhat expensive."
"The initial setup is pretty complex. There's a learning curve, and its cost varies across different environments. It's difficult."
"The solution lacks features when compared to some of the competitors such as Prisma Cloud by Palo Alto Networks and has room for improvement."
"I wish the container could be more lightweight so that anyone can test and verify SUSE Rancher Prime."
"There are a lot of issues in the tool, such as addressing the errors, addressing the stability, and addressing the reliability."
"It would be beneficial to have more support for the product."
"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."
"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."
"Some initial setup and configuration were required by the admin side for enabling security policies, which were not supported initially."
"I think SUSE Rancher could be improved by having the documentation more centralized, though it is not that problematic currently."
"During major version upgrades, the process can become a bit complex, especially in air-gapped environments where image management and dependencies require extra planning."
