@HoussemNasri I would appreciate if you could also take a look here.


- **CSAF**, maintained by OASIS. Supports rich metadata, including product information, vulnerabilities, and remediation guidance.
- **CycloneDX**, is maintained by OWASP. Focuses on simplicity and interoperability. (Can be JSON or XML-based)
- **OpenVEX**, designed specifically for simplicity and ease of use. It is maintained by the OpenVEX community.

I strongly recommend CycloneDX, because as you said is maintained by OWASP.
I'd also suggest to check whether we could use a system like DependencyTracker (https://docs.dependencytrack.org/) to identify and reduce risk in the software supply chain.

Hi! The trouble here is that we're not generating new VEX files, but consuming those provided by vendors like SUSE. So we're limitated to the format they have chosen. For example SUSE provides VEX files in CSAF and OpenVEX formats.

Juat two notes, otherwise looks good to me.

I would add a line saying that the data will be processed in stream, to avoid any memory issues.3
