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

"Once it is set up, Qualys has proved to be one of our greatest assets."
"The biggest strengths of Qualys TotalCloud are that it is pretty good at cloud visibility, has easy integration, and also has multi-cloud compatibility."
"TruRisk Insights is the most important innovation they've released this year."
"Qualys TotalCloud fulfills all these needs."
"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."
"The most valuable feature is the consolidated information that it provides from various platforms."
"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."
"If someone were to ask me to review Qualys TotalCloud, I would summarize it as an end-to-end solution for cloud security with visibility and governance-grade controls without needing to manage multiple disconnected tools."
"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."
"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 our organization by helping our teams achieve greater results in delivering end-to-end initiatives."
"SUSE Rancher has positively impacted my organization by making the teams' work easier and reducing project delivery time."
"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."
"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 helps me manage and automate processes with Kubernetes through full integration from hardware to application."
"By using Nessus, we are able to finish testing with assured results, in half the time."
"The strong security provided by the product in the container environment is its most valuable feature."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"Nessus scanner is very effective for internal penetration testing."
"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."
"It is a scalable solution. Scalability-wise, it is a good solution."
 

Cons

"I would appreciate additional integration options to connect Qualys TotalCloud with our other vulnerability management tools."
"TotalCloud could improve the classification of vulnerabilities. Specifically, it could enhance the categorization of what aspects fall under patches resolved by OS or software updates and what pertains to configuration adjustments."
"In a future release, I suggest that zero-day vulnerabilities should be predicted in advance using AI technologies. The system is not 100% secure yet, so proactive threat hunting could be enhanced to be more proactive than the current system."
"With the growing integration of AI, I would like Qualys to enhance its service offerings to better accommodate AI-related risks."
"There is room for improvement in the support."
"In my opinion, what can be improved in Qualys TotalCloud includes pricing and container scanning."
"A feature improvement could be the inclusion of Windows OS support for container security, as it is currently only supported for Linux."
"Overall, we are satisfied with it. However, the response part of the Cloud Detection and Response (CDR) module can be improved. It is not yet in place according to requirements; it is not completely available even though the module has been released."
"An improvement I wish for with SUSE Rancher is that we once had issues regarding some driver problems for the network on a particular laptop, and we had a hard time finding the exact error occurring."
"Additional features for a paid solution should be included, such as more detailed insights, better graphics, and an improved user interface."
"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."
"It would be beneficial to have more support for the product."
"During major version upgrades, the process can become a bit complex, especially in air-gapped environments where image management and dependencies require extra planning."
"Some initial setup and configuration were required by the admin side for enabling security policies, which were not supported initially."
"Regarding the platform's features and advantages, it is unfortunate that observability and some artificial intelligence functionality work fully only with a paid subscription."
"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."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"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."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"They need to work on auto-remediation so it's easier for the security team to act quickly when certain assets or resources are deployed. The latest version has a CIS benchmark that you need to meet for containers in the cloud, but more automation is needed."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"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."
"The solution’s pricing could be improved."
