Cool project! Phylum looks useful at addressing a few worries I have with Python. Would it work in a mostly air-gapped environment, or does it have to call home regularly?
This is currently offered as a SaaS solution, but we'll be providing an on-prem offering by EOY that should work well in an air-gapped environment.
The sandbox I mentioned above is rolled into our CLI by default, but that should operate well enough on its own without needing to call out to our API if you wanted!
