One of the hardest things to get any dev organization to start taking seriously is supply chain security. That first scan which lights up like a Christmas Tree is always such a daunting obstacle to get over. It's a shame because it is probably the highest value SDLC practice that many are not doing.
Yet, the base Debian image _does_ light up like a Christmas tree when you run a snyk scan. Mostly with incorrect issues (version number causes a flag but the fix is backported) or are considered low priority and thus WONTFIX by upstream.
If you’re writing software against, say, dotnet3 (which has a docker image based on Debian) then you’re basically noised out.
