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

"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."
"I found the initial setup user-friendly."
"Qualys TotalCloud provides unified vulnerability and threat assessment for IaaS and SaaS and a single prioritized view of risk, which helps reduce my workload by not having to combine multiple sources."
"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."
"If someone were to ask me to review Qualys TotalCloud, I would summarize it as an end-to-end solution for cloud security with visibility and governance-grade controls without needing to manage multiple disconnected tools."
"The platform's unified view of the organization proves particularly valuable for leadership team meetings."
"I would definitely recommend it because it is easy to handle any cloud resources."
"I would definitely recommend Qualys TotalCloud to other users."
"Offers easy management with authentication and authorization features"
"I am impressed with the tool's visibility."
"It is easy to install and manage."
"The technical support is good."
"The most valuable feature of the solution is its monitoring feature."
"The most beneficial security feature of the product revolves around the areas of vulnerability and configuration."
"One of the most valuable features I found was the ability of this solution to map the network and show you the communication between your containers and your different nodes."
"Segmentation is the most powerful feature."
"Rancher Desktop provides support for Kubernetes setup on local machines."
"SUSE Rancher has positively impacted my organization by making the teams' work easier and reducing project delivery time."
"SUSE Rancher has positively impacted my organization with increased efficiency in a 10x manner."
"The end-to-end deployment was at least 30 percent cheaper than OpenShift, which was the biggest criterion since customers are cost-conscious."
"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, and it has very good customer support, and it is very easy to understand in terms of usage."
"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."
"I could say that with SUSE Rancher, we've managed to cut the provisioning time to probably one-tenth of the usual provisioning time."
 

Cons

"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."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"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."
"We would like to see Windows-based sensors available in Qualys, as this would make the platform more versatile and support a broader range of environments."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"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."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"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 support and specifications need to be up to date for the cluster technologies"
"The solution lacks features when compared to some of the competitors such as Prisma Cloud by Palo Alto Networks and has room for improvement."
"The solution's visibility and vulnerability prevention should be improved."
"The testing process could be improved."
"The initial setup is pretty complex. There's a learning curve, and its cost varies across different environments. It's difficult."
"The documentation about Red Hat Advanced Cluster Security available online is very limited... So it's very limited to the documentation."
"The deprecation of APIs is a concern since the deprecation of APIs will cause issues for us every time we upgrade."
"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."
"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."
"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."
"It would be beneficial to have more support for the product."
"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."
