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.

Has significantly improved proactive monitoring through automated asset discovery and seamless integration with cloud environments

Making the system smarter would be beneficial. Adding modules for integration with AWS and Azure would be helpful. Adding capabilities for the scanner to automatically pick up changes and add assets automatically would be valuable. When discussing a big company, it is mandatory to have tools that will assist us rather than waiting for manual input to add hosts. Adding assets manually is prone to mistakes. Humans might forget to add an asset or make errors when adding multiple assets. Taking the human element out of the context and making it more streamlined is the future for security. The human should be involved where expertise is needed, such as analysis and decision-making. Currently, with resource constraints, we need tools to collect and aggregate data, eliminate false positives as much as possible, and present relevant information to employees for action.

More Qualys TotalCloud pros

"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."

"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."

"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."

"Tenable Cloud Security excels in vulnerability detection, one of its strongest features. Another valuable feature is software composition analysis, which highlights and automates the detection of security flaws. Additionally, their knowledge base is excellent; if anything goes wrong, they provide clear guidance on what needs to be done to address specific vulnerabilities."

"Scanning and reporting are the most valuable features of Tenable Cloud Security"

"Ermetic can provide super visibility for our cloud environment (we are using AWS), the dashboard is simple to use, the findings provide all of the information you require, it provides detection and remediation, and creating a Jira ticket from a finding is just one click away."

More Tenable Cloud Security pros

Cons

"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."

"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."

"I think Qualys TotalCloud needs to improve its handling of zero-day vulnerabilities and supply chain management because modern ransomware attacks not only target prime critical infrastructures but also the supply chain system."

"There is room for improvement in the support."

"The cost of Qualys TotalCloud is high and could be more competitive."

"The response part of the Cloud Detection and Response (CDR) module can be improved."

"Qualys's ticketing system can be confusing when assigning tasks to individuals, and support could be improved by offering instant call solutions with engineers in addition to ticket replies."

"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."

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

"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 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."

"We still maintain Tenable Cloud Security but have reduced the number of licenses. We now use it occasionally to validate specific items rather than monitoring the entire surface, for which we use Element."

"In my experience, Tenable Cloud Security is not very stable."

"Tenable needs to offer a patch-based solution since it is an area where the tool lacks a bit."

"Due to its robust nature, the platform's adoption can be overwhelming initially. However, once organizations start using it, they tend to get used to it. I haven't had much direct interaction with the support team, but some partners have reported a desire for better support for the product."

"The product must provide more features."

"If Tenable Cloud Security offers a complete Cnapp solution with CWP, CIEM, and Waap security, it will be able to compete with other competitors."

"I do think there might be room for more integrations. This could allow for further customization and flexibility, essentially offering different functionality options to accommodate various budgets."

"There is a need for the support team to improve their response time since it is one of the areas where the product's technical team has certain shortcomings."

More Tenable Cloud Security cons
