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.

Secures container builds, has simplified compliance audits and reduced vulnerabilities dramatically
The benefit of Chainguard Containers is that it makes development simpler. It makes the development team confident there will not be any bugs or vulnerabilities in the image they are using. It is mainly needed for vulnerabilities, SLAs, security audits, and SOC 2, ISO, and PCI compliance. The image includes SBOM, signature, and provenance metadata, which makes audits much easier. The best features Chainguard Containers offers include a reduced image size. It removes the shell and the package manager, resulting in a significantly smaller image size compared with a normal image. We can deploy production workloads directly without worrying about security concerns. If we want a strong supply chain for security, we will be using it. Many users are already tired of scanning alerts, so this will be a great thing. Removing the shell and package manager has positively impacted my team's workflow and deployment speed by making it quite user-friendly, where the developer can touch it without any hesitation. Chainguard Containers are built and pushed from non-patched binaries, with the packages compiled directly from the source. No dependencies or pre-built distro packages like Debian or Alpine are required, so there are no hidden vulnerabilities. The developer gains full control over what goes inside, and the image size is smaller with fewer vulnerabilities, in fact, zero. It has built-in processes like SBOM, which is Software Bill of Material generated. The image is cryptographically signed, and provenance is tracked, leading to faster patching, minimal footprint, and best supply chain control. Chainguard Containers has positively impacted my organization by reducing constant CVE fixing, resolving security versus DevOps conflicts, and minimizing compliance headaches. After implementing secured-by-default containers, there is less effort on fixing vulnerabilities, faster delivery, and better compliance. The impact on security teams includes a lower risk of attack, less panic during audits, and significantly fewer security noises. A specific outcome we have noted since implementing Chainguard Containers is that for a client who uses more than 200 containers, they previously received vulnerability warnings for every deployment. Once we implemented Chainguard Containers, the vulnerability ratio drastically decreased, from 100 to 30. Nearly 70% of the vulnerability checks have passed. Chainguard Containers are CVE-resistant, which is significant as CVEs represent Common Vulnerabilities and Exposures.

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

"The platform's unified view of the organization proves particularly valuable for leadership team meetings."
"I would recommend Qualys TotalCloud to other users because it is cost-efficient and has a good return on investment."
"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 most valuable feature is extensibility."
"I appreciate TotalCloud's real-time protection and remediation features. The remediation options include automated one-click remedies and custom changes that help manage vulnerabilities efficiently."
"Qualys TotalCloud has significantly reduced our workload in terms of managing risks, helping us to be more efficient and save substantial resources."
"Qualys TotalCloud has improved our security posture."
"Qualys TotalCloud has significantly improved our organization by automating our reporting processes, reducing the time spent on report creation from two hours to less than fifteen to twenty minutes."
"Specific outcomes and metrics show that before this, every month there would be 15 to 20 vulnerabilities, but after switching to Chainguard Containers, there are now only one or maybe two vulnerabilities."
"The best feature of Chainguard Containers is being distroless, and the main thing I liked about it is that they follow the SBOM process and the continuous rebuilds they were doing, and they were helping me to rapidly remediate the failures which were happening."
"Chainguard Containers has positively impacted my organization even during the proof of concept phase by improving our security posture."
"Chainguard Containers has positively impacted my organization by reducing constant CVE fixing, resolving security versus DevOps conflicts, and minimizing compliance headaches."
"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 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."
"The end-to-end deployment was at least 30 percent cheaper than OpenShift, which was the biggest criterion since customers are cost-conscious."
"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 has positively impacted my organization with increased efficiency in a 10x manner."
"SUSE Rancher has positively impacted my organization by making the teams' work easier and reducing project delivery 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."
 

Cons

"The support is not up to the mark and seems to be overburdened."
"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."
"The main area needing improvement is integration. Although the team is strengthening TotalCloud, integration can be enhanced with SIEM, SOAR, ITSM, and other sources."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"In a future release, I suggest that zero-day vulnerabilities should be predicted in advance using AI technologies. The system is not 100% secure yet, so proactive threat hunting could be enhanced to be more proactive than the current system."
"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"The cost of Qualys TotalCloud is high and could be more competitive."
"Sometimes there are backend errors which we come across again and again, and there is a resolution, but there are pending tickets for it. That sucks sometimes."
"The accuracy and reliability of the output from Chainguard Containers are below average, but I still give it an average rating of 6.5 to 7 because of its capabilities and its functionality for a developer-friendly approach."
"The biggest challenge in Chainguard Containers is that they provide minimal images, which can make troubleshooting difficult because common debugging tools are also not included."
"The only limitation or challenge that stood out during my evaluation of Chainguard Containers was the fact that it is primarily based on Alpine, which can be tricky to use in native Kubernetes environments, as we use Tecton primarily, which is a CI/CD pipeline that runs on native Kubernetes."
"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."
"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."
"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."
"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."
"Additional features for a paid solution should be included, such as more detailed insights, better graphics, and an improved user interface."
 

Pricing and Cost Advice

"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"I am not sure about the pricing. From what I understand, it is a bit on the higher side, but I do not have the exact numbers."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"Qualys TotalCloud is expensive."
"Its price seems higher compared to other tools, but it is worth it. If they could adjust the pricing and make it comparable with other tools, that would be great."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
