Tenable.io CS helps us secure all our workloads in the cloud that are placed inside containers. It checks for misconfiguration and vulnerabilities at the container level. 

We use this product for scanning the containers and the vulnerabilities. Many of our clients install it in the CI/CD platform on DevOps and when building their applications. We also used it for scanning purposes when the code was being built. It effectively tells us about the vulnerabilities that occur during the build phase.

My company has gone through the product named Tenable.io Container Security. Tenable.io Container Security is to help you out in a cluster environment, where you need to have containers like Docker or similar products and should be able to use them for production while also being able to avail some detection capabilities.

The company offers two solutions: Container Security, a product concentrated on scanning vulnerabilities in on-prem environments, and Cloud Security, a solution specifically designed for scanning container vulnerabilities in cloud environments. The latter includes options for integration with cloud services and DevOps pipelines.

The product is used to protect the applications in the container environment. It is used by customers that are more mature in their security procedures.

We use Nessus Scanner for internal and external penetration testing activities. The tool in internal penetration testing activities is very useful, but requires regular updating of the patches which requires certain memory and RAM space in the installed server.
