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.

Provides network mapping feature for visualizing container communication but complex setup
There is room for improvement in the setup process. All these tools come down to how you're integrating into your environment and having good knowledge of the tool. So that's the biggest problem with all these security tools – you gotta have knowledgeable people to build, integrate, and really flesh them out in your environment to make them work as they should.

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.

Quotes from Members

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

Pros

"The agent and agentless scanning in TotalCloud, particularly the FlexScan method, is incredibly valuable. With traditional scanning approaches, we had to give IP ranges and whitelist IPs. All that is now simplified. FlexScan requires minimal intervention, and after configuration, it automatically collects data and performs necessary scans."
"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."
"The best features in Qualys TotalCloud include the total asset management of the cloud environment. It is very easy to export the report and see the vulnerabilities related to the cloud specifically."
"One of Qualys' best features is its categorization, which allows us to see the types of assets, their security postures, and the AI-powered version of the tool."
"I depend heavily on the reports that I have from this tool."
"The dashboards are particularly valuable as they offer a comprehensive view of the environment, highlighting any misconfigurations."
"Qualys TotalCloud helps you not just to identify misconfigurations, but you can actually also fix issues."
"Qualys TotalCloud's most valuable features are its security capabilities that help identify and mitigate risk factors."
"I am impressed with the tool's visibility."
"It is easy to install and manage."
"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."
"The most valuable feature is the ability to share resources."
"The most beneficial security feature of the product revolves around the areas of vulnerability and configuration."
"The benefit of working with the solution is the fact that it's very straightforward...It is a perfectly stable product since the details are very accurate."
"The most valuable feature of the solution is its monitoring feature."
"The technical support is good."
"SUSE Rancher has positively impacted our organization by helping our teams achieve greater results in delivering end-to-end initiatives."
"I could say that with SUSE Rancher, we've managed to cut the provisioning time to probably one-tenth of the usual provisioning time."
"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."
"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."
"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."
"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."
 

Cons

"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"
"There should be improvement from a dashboard perspective when collecting and showcasing data to lead management."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"In TotalCloud, I would suggest improvements in policy checks to cater to various inventory types like VPCs, subnets, S3 buckets, or IAMs. There is a lack of data segregation according to criticality or inventory."
"The onboarding process is a bit difficult. In the initial phase, it is very difficult to understand the features, what the dashboard contains, and what criteria they are using."
"Their support could be improved."
"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."
"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."
"The solution's price could be better."
"The solution's visibility and vulnerability prevention should be improved."
"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."
"Red Hat is somewhat expensive."
"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."
"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."
"All the tasks that SUSE Rancher does can be done in alternative methods, so it is not a must-have or a necessary tool in my view."
"There are a lot of issues in the tool, such as addressing the errors, addressing the stability, and addressing the reliability."
"Regarding the platform's features and advantages, it is unfortunate that observability and some artificial intelligence functionality work fully only with a paid subscription."
"An improvement I wish for with SUSE Rancher is that we once had issues regarding some driver problems for the network on a particular laptop, and we had a hard time finding the exact error occurring."
"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."
"It would be beneficial to have more support for the product."
