>Rubysec is awesome but outdated, lacks many of the vulnerabilities in https://Snyk.io/

I'm one of the Rubysec maintainers.

If you're reading this and you know about vulns not present in the advisory-db, please submit a PR to the github repo, or use the crappy form we put together: https://rubysec.com/advisories/new

I too run a vulnerability notification service, and it's frustrating when other people use public data but don't contribute back.

Thank you for maintaining such a great service! You should promote your service as part of it.
