Our primary use case of this solution is for our CICD pipeline, to build and store our artifacts in the repository. I'm the principal engineer and we are customers of Sonatype. 

We are using Sonatype Nexus Repository for capturing or creating our software bill of materials, such as Maven, Python, no NPM, and Node.js Repos. They are open-source packages that we've scanned and that we want to keep as is. Additionally, we use it for our snapshots and releases of our own binaries.
