gokart VS trivy

Trivy is a mature and comprehensive open source tool from Aqua Security that supports scanning multiple sources, from file systems to containers and VMs. Trivy also looks beyond vulnerabilities, to scan licenses, secrets, infrastructure as code misconfiguration, and more.

I would suggest to think about the thread model that you are facing so you can have a better mental model of the weak points of your environment. The very very big majority of these attacks will be automated probing for publicly known vulnerabilities or default credentials. That means the maintainers of the software you are running and the channels on which their updates are shipped to you and deployed are very important factors. For software that is not installed from a trusted and well maintained source (e.g. Ubuntus main repository), you want to make extra sure that vulnerabilities are updated. E.g. your deployed docker containers might contain security issues, you can run checks on these with tools like trivy. The same is also true for appliances, in case your router or firewall contains a software vulnerability, how will you be notified and how will the required updates be deployed?

Trivy to scan your Container Image, for example as an Artefact finished building for your application in CI/CD.

The combination of a smaller attack surface and up-to-date, patched packages in Wolfi results in less (always aiming for ZERO) CVEs. This can be demonstrated in the results obtained from Trivy when scanning the most popular PHP images on Docker Hub (with data from March 2, 2023) and comparing them with the Wolfi-based PHP image maintained by Chainguard:

There was a discussion, https://github.com/NginxProxyManager/nginx-proxy-manager/discussions/1812 , where docker container where analyzer by Trivy (a securitu scanner) https://github.com/aquasecurity/trivy and lot of library where old and exploitable.
