Secured container workloads have reduced noise and monitoring improves with better debugging options
There are a lot of certain points where I feel that having the functionality of having debugging and ensuring that if I like, I can have the dependence of things where things I felt were lacking. Overall, the tool itself is kind of a great start for my evaluation. Because we are currently evaluating, we will have much more of an understanding of this tool again in the near future. If you talk about the concurrent processing, there is some bit of mismanagement happening in Chainguard Containers, which I do not like about it and which is kind of a deal breaker for me. On terms of scalability, because it is hosted on Kubernetes, there is no issue with the scaling and handling the infrastructure. However, when it comes to processing, there is a kind of a bit of a delay which happens. For most customers, this will not be relevant because what we deal with is the concurrency, and for us, every microsecond counts. So for our use case, perhaps that is a limitation, but for the overall market, I do not think that will be a great limitation for them. I'll say that having debugging possibilities can actually help to improvise Chainguard Containers more because as a product, I see a lack of visibility on that. Perhaps I might be wrong. I do not know exactly the way to do it. I am still in the evaluation process. That is one thing. The second thing is that there were no quick fixes available. That is problematic because if you are not able to configure it yourself, you should be able to get those quick fixes right away so that you can continue with your work. You need a detailed discipline if you want to debug those things because it is kind of a mess when you start debugging these containers when they fall. That is why I am still evaluating tools where I can get the balance of both.

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

"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."
"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."
"The strong security provided by the product in the container environment is its most valuable feature."
"Nessus scanner is very effective for internal penetration testing."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"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 tool's most valuable feature is scanning, reporting, and troubleshooting."
 

Cons

"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 stability and setup phase of the product are areas with shortcomings where improvements are needed."
"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."
"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 initial setup is highly complex."
"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."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"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."
