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.

An operational system, similar to Linux where you can run your applications inside containers

With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers. When you mentioned using Nacula as part of your CI/CD pipeline, it means your application is deployed and managed automatically through the CI/CD process. Containers are used to deploy your application within this pipeline, but CoreOS does not run inside these containers. Instead, CoreOS is the base operating system that supports and manages these containers.

Quotes from Members

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

Pros

"Qualys TotalCloud's most valuable feature is its ability to link clusters of assets, providing a clear model of deployments, vulnerabilities, and statuses."

"The most valuable feature of Qualys TotalCloud is the visibility it provides."

"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."

"While automatic inventory detection upon connection is a helpful feature, a truly valuable capability would be assessing an environment's security posture against Azure and CIS best practices."

"We were able to realize its benefits within 24 to 48 hours."

"Qualys TotalCloud provides a single, prioritized view based on requirements such as identifying the most vulnerable assets and calculating the average time to remediate vulnerabilities."

"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."

"Qualys TotalCloud fulfills all these needs."

More Qualys TotalCloud pros

"Chainguard Containers has positively impacted my organization by reducing constant CVE fixing, resolving security versus DevOps conflicts, and minimizing compliance headaches."

"Chainguard Containers has positively impacted my organization even during the proof of concept phase by improving our security posture."

"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."

"CoreOS Clair's best feature is detection accuracy."

"With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers."

"CoreOS Clair can be used by organizations of any size."

Cons

"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."

"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."

"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."

"Although TotalCloud is a helpful tool, some of its advanced features are still under development."

"Qualys TotalCloud has the potential to improve by integrating a hybrid platform for comprehensive management of both on-premises and cloud infrastructures."

"The areas in the solution that have room for improvement include the UI/UX design, which should be improved, and they should integrate more artificial intelligence into the product."

"I would like the ability to disable certain default built-in policies as they can be misleading when creating dashboards. That is the top one."

"There is a lack of data segregation according to criticality or inventory."

More Qualys TotalCloud cons

"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 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."

"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 biggest challenge in Chainguard Containers is that they provide minimal images, which can make troubleshooting difficult because common debugging tools are also not included."

"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."

"It can be improved in its support response. They usually take up to seven days to resolve the issue."

Pricing and Cost Advice

"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."

"TotalCloud's price is about right where I would expect it to be."

"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."

"Qualys TotalCloud is expensive."

"The cost is high, but it meets our organizational needs."

"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."

"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."

"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
