Centralized management has unified multi‑cluster operations across clouds and data centers
There are multiple areas where SUSE Rancher can improve. The most pressing issue that I found in SUSE Rancher is that it is a bit slow. Compared with Komodor, it is very slow. Maintenance is also very high, and we require regular maintenance. Non-experts in Kubernetes cannot handle this application. It is a bit less stable compared with other tools in the market. In most regions, there is scope for improvement. There is a lot of scope for improvement, and there are a lot of issues in the tool, such as addressing the errors, addressing the stability, and addressing the reliability. It is a very good tool, so that is why I gave it a nine. However, it is not a great tool to get a ten. It is a bit costly compared with other tools in the market.

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 most valuable features of SUSE Rancher include the user interface and the display features."
"Rancher Desktop provides support for Kubernetes setup on local machines."
"SUSE Rancher is best used for large-scale applications such as ours; it manages very high-end infrastructure, has very good customer support, and is very easy to understand in terms of usage."
"Rancher Desktop provides support for Kubernetes setup on local machines."
"SUSE Rancher has positively impacted my organization with increased efficiency in a 10x manner."
"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 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 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."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"Nessus scanner is very effective for internal penetration testing."
"It is a scalable solution. Scalability-wise, it is a good solution."
"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 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."
"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."
 

Cons

"Some initial setup and configuration were required by the admin side for enabling security policies, which were not supported initially."
"There are a lot of issues in the tool, such as addressing the errors, addressing the stability, and addressing the reliability."
"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."
"Additional features for a paid solution should be included, such as more detailed insights, better graphics, and an improved user interface."
"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."
"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."
"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 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. 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."
"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 initial setup is highly complex."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
