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.

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.

Detailed container image reports have improved vulnerability insight and support secure operations
Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning. Tenable.io Container Security is giving me the vulnerability information of Docker images and the information about software bill of materials. However, my challenge at this time is that I am using all these solutions with GitLab Ultimate, and it does not support integration, so I am doing some alternate arrangements which are giving me operational complexity because I need to introduce something else instead of GitLab Ultimate. That is the primary concern regarding the benefits of real-time visibility into my containerized application security status.

Quotes from Members

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

Pros

"TotalCloud has been excellent in providing us with immediate access to all the products and features we need, such as CSPM, TruRisk Insights, and compliance reports, including CIS and HIPAA."
"I would definitely recommend it because it is easy to handle any cloud resources."
"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 of Qualys TotalCloud is the visibility it provides."
"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."
"In my opinion, this is the best tool."
"Its dashboards are brilliant. It provides in-depth insights."
"The best feature would be the ability to create policies. It is easy to control and update policies as required."
"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."
"SUSE Rancher has positively impacted my organization by making the teams' work easier and reducing project delivery time."
"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."
"The end-to-end deployment was at least 30 percent cheaper than OpenShift, which was the biggest criterion since customers are cost-conscious."
"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 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 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."
"SUSE Rancher has positively impacted my organization with increased efficiency in a 10x manner."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"By using Nessus, we are able to finish testing with assured results, in half the time."
"It is a scalable solution. Scalability-wise, it is a good solution."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"Tenable.io detects misconfiguration when you deploy a Docker or Kubernetes container. It's much better to remedy these issues during deployment instead of waiting until the container is already in the production environment."
"The strong security provided by the product in the container environment is its most valuable feature."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
 

Cons

"I would appreciate additional integration options to connect Qualys TotalCloud with our other vulnerability management tools."
"Their support could be improved."
"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."
"In my opinion, what can be improved in Qualys TotalCloud includes pricing and container scanning."
"Qualys TotalCloud has the potential to improve by integrating a hybrid platform for comprehensive management of both on-premises and cloud infrastructures."
"It is already perfect, but they can bring some newer dashboards and customization options for the dashboard. It would be great to be able to include on-prem assets on the dashboard."
"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."
"One thing that could be improved is the user experience and navigation."
"It would be beneficial to have more support for the product."
"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."
"During major version upgrades, the process can become a bit complex, especially in air-gapped environments where image management and dependencies require extra planning."
"Regarding the platform's features and advantages, it is unfortunate that observability and some artificial intelligence functionality work fully only with a paid subscription."
"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."
"I wish the container could be more lightweight so that anyone can test and verify SUSE Rancher Prime."
"The solution’s pricing could be improved."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"I feel that in certain areas this product has false positives which the company should work on."
"I believe integration plays a crucial role for Tenable, particularly in terms of connecting with other products and various container solutions like Docker or Kubernetes. It seems that in future updates, enhanced integration is something I would appreciate. Currently, there is integration with Docker, but when it comes to Kubernetes or other container solutions, it appears to be a challenge, especially with on-prem scanners."
"However, my challenge at this time is that I am using all these solutions with GitLab Ultimate, and it does not support integration, so I am doing some alternate arrangements which are giving me operational complexity because I need to introduce something else instead of GitLab Ultimate."
"I feel that in certain areas this product has false positives which the company should work on. They should also try to include business logic vulnerabilities in the scanner testing. Finally, the vulnerability assessment feature should be increased to other hardware devices, apart from firewalls."
"The initial setup is highly complex."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
