Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

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

"One of the most valuable features of Qualys TotalCloud is FlexScan, which is specifically for internet-facing VMs. We found this feature to be very useful. It was a key differentiator for us."
"Qualys TotalCloud provides a single, prioritized view of risk, reducing the workload associated with consolidating multiple sources for risk prioritization."
"I appreciate Qualys TotalCloud's ability to onboard any type of device with ease, including containers."
"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."
"Its dashboards are brilliant. It provides in-depth insights."
"The most valuable feature is extensibility."
"Qualys TotalCloud has significantly reduced our workload in terms of managing risks, helping us to be more efficient and save substantial resources."
"Rancher Desktop provides support for Kubernetes setup on local machines."
"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."
"SUSE Rancher has positively impacted my organization by making the teams' work easier and reducing project delivery 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 has positively impacted my organization with increased efficiency in a 10x manner."
"SUSE Rancher has positively impacted our organization by helping our teams achieve greater results in delivering end-to-end initiatives."
"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."
"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."
"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."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"The strong security provided by the product in the container environment is its most valuable feature."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"It is a scalable solution. Scalability-wise, it is a good solution."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
 

Cons

"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."
"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."
"There is room for improvement in the support."
"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"A feature improvement could be the inclusion of Windows OS support for container security, as it is currently only supported for Linux."
"It has been working very well, but it would be helpful if the dashboard could generate reports tailored to specific compliance needs. For example, in India, we have to comply with RBI and SEBI guidelines. It w"
"Qualys TotalCloud needs to enhance its scanning capabilities in the IP domain, as it currently lacks the functionality to resolve IPs to their corresponding domain names."
"Regarding the platform's features and advantages, it is unfortunate that observability and some artificial intelligence functionality work fully only with a paid subscription."
"During major version upgrades, the process can become a bit complex, especially in air-gapped environments where image management and dependencies require extra planning."
"I think SUSE Rancher could be improved by having the documentation more centralized, though it is not that problematic currently."
"There are a lot of issues in the tool, such as addressing the errors, addressing the stability, and addressing the reliability."
"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."
"It would be beneficial to have more support for the product."
"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."
"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."
"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."
"I feel that in certain areas this product has false positives which the company should work on."
"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."
