Risk-based triage has transformed container security and now prioritizes high-impact threats
The best features Qualys TotalCloud offers currently include managing cloud infrastructure and container security while facing major challenges such as alert fatigue. Traditional vulnerability scanners flag hundreds of CVEs on short-lived Kubernetes containers, some of which have no internet exposure or are gone before we can even triage them. I leverage Qualys TotalCloud to move beyond static CVSS. I use it to implement runtime exposure, correlation risk reprioritization, and shift-left integration. This notifies developers to fix a base image upstream rather than patching live ephemeral instances. In my work with cloud and container security, the biggest operational hurdle was alert fatigue. I use Qualys to shift left from static CVSS severity to context-aware risk prioritization. I correlated raw vulnerability data with real-time risk factors such as public network exposure, active runtime execution, or overly permissive IAM roles. This allows us to immediately drop the priority of isolated containers and escalate lower-severity CVEs that sit on an exposed, high-risk path. We can map these findings directly back to our CI/CD pipelines so developers can patch the root base images upstream. We have drastically cut down the signal-to-noise ratio, saved a lot of manual hours doing triage work, and ensured engineering effort goes directly towards high-impact risk reduction.

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.

Detailed container image reports have improved vulnerability insight and support secure operations
Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning. Tenable.io Container Security is giving me the vulnerability information of Docker images and the information about software bill of materials. However, my challenge at this time is that I am using all these solutions with GitLab Ultimate, and it does not support integration, so I am doing some alternate arrangements which are giving me operational complexity because I need to introduce something else instead of GitLab Ultimate. That is the primary concern regarding the benefits of real-time visibility into my containerized application security status.

Quotes from Members

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

Pros

"I would recommend Qualys TotalCloud to other users because it is cost-efficient and has a good return on investment."
"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."
"Qualys TotalCloud's most valuable feature is its agent versatility."
"Qualys TotalCloud fulfills all these needs."
"I found the initial setup user-friendly."
"Qualys TotalCloud's most valuable feature is its ability to link clusters of assets, providing a clear model of deployments, vulnerabilities, and statuses."
"Qualys TotalCloud has helped us view our risk structure, vulnerabilities, and security posture."
"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."
"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."
"Chainguard Containers has positively impacted my organization even during the proof of concept phase by improving our security posture."
"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 by reducing constant CVE fixing, resolving security versus DevOps conflicts, and minimizing compliance headaches."
"By using Nessus, we are able to finish testing with assured results, in half the time."
"Tenable.io detects misconfiguration when you deploy a Docker or Kubernetes container. It's much better to remedy these issues during deployment instead of waiting until the container is already in the production environment."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"Currently, I haven't implemented the solution due to its deprecation by the site. However, I can highlight some benefits of Tenable Cloud Security, a cybersecurity solution with various features for scanning vulnerabilities in both cloud environments and on-premises container security."
"The strong security provided by the product in the container environment is its most valuable feature."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
 

Cons

"The response part of the Cloud Detection and Response (CDR) module can be improved."
"The cost of Qualys TotalCloud is high and could be more competitive."
"Enhancing clarity regarding its compliance capabilities would be beneficial, as the current scope is limited in geographic coverage."
"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."
"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."
"A feature improvement could be the inclusion of Windows OS support for container security, as it is currently only supported for Linux."
"One thing that could be improved is the user experience and navigation."
"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."
"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."
"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 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."
"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."
"I believe integration plays a crucial role for Tenable, particularly in terms of connecting with other products and various container solutions like Docker or Kubernetes. It seems that in future updates, enhanced integration is something I would appreciate. Currently, there is integration with Docker, but when it comes to Kubernetes or other container solutions, it appears to be a challenge, especially with on-prem scanners."
"I feel that in certain areas this product has false positives which the company should work on. They should also try to include business logic vulnerabilities in the scanner testing. Finally, the vulnerability assessment feature should be increased to other hardware devices, apart from firewalls."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"I feel that in certain areas this product has false positives which the company should work on."
"The initial setup is highly complex."
"The solution’s pricing could be improved."
"However, my challenge at this time is that I am using all these solutions with GitLab Ultimate, and it does not support integration, so I am doing some alternate arrangements which are giving me operational complexity because I need to introduce something else instead of GitLab Ultimate."
"They need to work on auto-remediation so it's easier for the security team to act quickly when certain assets or resources are deployed. The latest version has a CIS benchmark that you need to meet for containers in the cloud, but more automation is needed."
