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.

Offers easy management and container connection with HTTPS, but the support needs to improve
I have experience with the solution's setup in Rio de Janeiro, Brazil and our company has assisted in the development of a cluster in a research department, but we didn't start from scratch because we have IT professionals who have installed Kubernetes across 12 nodes of a cluster and a new environment can be created for a new platform. I also had another setup experience of Red Hat Advanced Cluster Security for Kubernetes in Portugal where I had to implement the solution in a cluster of 22 computer servers, which was completed with assistance from the IT department of the company. The initial setup process of the solution can be considered as difficult. The setup process involves using the permissions, subnets and range of IPs, which makes it complex. Deploying Red Hat Advanced Cluster Security for Kubernetes takes around eight to ten hours for new clusters. The solution's deployment can be divided into three parts. The first part involves OpenStack, where the cluster's resources need to be identified. The second part involves virtualizing assets and identifying other physical assets, for which OpenStack, Kubernetes, or OpenShift are used. The third part of the deployment involves dividing the networks into subnetworks and implementing automation to deploy the microservices using Helm. The number of professionals required for the solution's deployment depends upon the presence of automated scripts. Ideally, two or three professionals are required to set up Red Hat Advanced Cluster Security for Kubernetes.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"CSPM is currently the most used feature, and we are enjoying the new feature, FlexScan, which is valuable for Internet-facing VMs."
"I like the web API security and IoT scanning features the most. The user-friendly design of TotalCloud's interface enables customers to navigate it and use its full potential easily"
"The vulnerability management feature is the one I like the most because it provides a clear picture of all vulnerabilities."
"I would definitely recommend it because it is easy to handle any cloud resources."
"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."
"The dashboards are particularly valuable as they offer a comprehensive view of the environment, highlighting any misconfigurations."
"Qualys TotalCloud's most valuable feature is its agent versatility."
"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."

"Segmentation is the most powerful feature."
"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 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 end-to-end deployment was at least 30 percent cheaper than OpenShift, which was the biggest criterion since customers are cost-conscious."
"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 helps me manage and automate processes with Kubernetes through full integration from hardware to application."
"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."
 

Cons

"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."
"TotalCloud could improve its scanning of niche devices like Wi-Fi dongles and USB modems because they are often untested. It covers everything else, like laptops, mobile devices, and Bluetooth IoT devices. They can improve on the small IoT devices because hackers and testers use these."
"Regarding technical support from Qualys, they respond, but the response time can be too long. Sometimes we need to wait weeks for solutions to simple questions."
"There is a lack of data segregation according to criticality or inventory."
"The main area needing improvement is integration. Although the team is strengthening TotalCloud, integration can be enhanced with SIEM, SOAR, ITSM, and other sources."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"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."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"The solution's price could be better."
"The documentation about Red Hat Advanced Cluster Security available online is very limited... So it's very limited to the documentation."
"The initial setup is pretty complex. There's a learning curve, and its cost varies across different environments. It's difficult."
"I do see that some features associated with the IAST part are not included in the tool, making it an area where improvements are required."
"The solution lacks features when compared to some of the competitors such as Prisma Cloud by Palo Alto Networks and has room for improvement."
"They're trying to convert it to the platform as a source. They are moving in the direction of Cloud Foundry so it can be easier for a developer to deploy it."
"The solution's visibility and vulnerability prevention should be improved."
"The deprecation of APIs is a concern since the deprecation of APIs will cause issues for us every time we upgrade."
"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."
"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 wish the container could be more lightweight so that anyone can test and verify SUSE Rancher Prime."
"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."
"Regarding the platform's features and advantages, it is unfortunate that observability and some artificial intelligence functionality work fully only with a paid subscription."
