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

"The scalability is good as well. I would rate it ten out of ten."
"While automatic inventory detection upon connection is a helpful feature, a truly valuable capability would be assessing an environment's security posture against Azure and CIS best practices."
"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."
"Once it is set up, Qualys has proved to be one of our greatest assets."
"I would rate Qualys TotalCloud ten out of ten."
"One of the features I appreciate is the ability to generate daily reports without relying on anyone else."
"Vulnerability and threat detection and assessment of the criticality of the vulnerabilities exposed are most valuable."
"Generally, Qualys is very good at detections, whether on cloud or on-prem, and the agent allows deployment on both infrastructures, providing continuous monitoring of your assets, which is a key selling point for us."
"Rancher Desktop provides support for Kubernetes setup on local machines."
"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."
"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."
"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 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 helps me manage and automate processes with Kubernetes through full integration from hardware to application."
"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 strong security provided by the product in the container environment is its most valuable feature."
"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."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"Nessus scanner is very effective for internal penetration testing."
"Currently, I haven't implemented the solution due to its deprecation by the site. However, I can highlight some benefits of Tenable Cloud Security, a cybersecurity solution with various features for scanning vulnerabilities in both cloud environments and on-premises container security."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
 

Cons

"Their support could be improved."
"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."
"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 patching process with Qualys Patch Management, which is part of TotalCloud, does not cover installing certain prerequisites on the servers or workstations. This shortcoming means we must rely on SCCM when any service stack updates or additional prerequisites are needed."
"The support is not up to the mark and seems to be overburdened."
"There should be improvement from a dashboard perspective when collecting and showcasing data to lead management."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"The cloud licensing unit system is unclear, especially since "units" aren't well-defined."
"During major version upgrades, the process can become a bit complex, especially in air-gapped environments where image management and dependencies require extra planning."
"It would be beneficial to have more support for the product."
"I think SUSE Rancher could be improved by having the documentation more centralized, though it is not that problematic currently."
"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."
"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."
"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."
"There are a lot of issues in the tool, such as addressing the errors, addressing the stability, and addressing the reliability."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"The initial setup is highly complex."
"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 solution’s pricing could be improved."
"I feel that in certain areas this product has false positives which the company should work on."
"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."
"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."
