Modernization of microservices and edge workloads has accelerated while integration still needs improvement
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. We had to move that deployment from VMware, which the customer wanted, to a bare metal solution. Flexibility also means better integrations with major industry solution providers like VMware, which many enterprise organizations use. The integrations with SUSE Rancher are fine, as long as you have open APIs, anyone can connect. For me, there were no challenges because we had standard products already certified. However, the integration between VMware and SUSE could definitely be improved. I chose 7 out of 10 because I faced VMware-related challenges as I explained. A lot of customers are still on VMware, while many also use Red Hat solutions, especially with the IBM push now. The marketing and outreach need to increase to penetrate more accounts, which are the two improvements I suggest.

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

"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 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 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 most valuable features of SUSE Rancher include the user interface and the display features."
"The end-to-end deployment was at least 30 percent cheaper than OpenShift, which was the biggest criterion since customers are cost-conscious."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"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."
"Nessus scanner is very effective for internal penetration testing."
"By using Nessus, we are able to finish testing with assured results, in half the time."
"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."
 

Cons

"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."
"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."
"There are a lot of issues in the tool, such as addressing the errors, addressing the stability, and addressing the reliability."
"Additional features for a paid solution should be included, such as more detailed insights, better graphics, and an improved user interface."
"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."
"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 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."
"The solution’s pricing could be improved."
"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."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"The initial setup is highly complex."
