This is the sticking point, because WhatsApp has now integrated Meta AI into the app, but (obviously) do not provide an on-prem data store. This is why Deepseek AI (the Deepseek app) and ChatGPT (the OpenAI app) are barred as well.
Data Stewardship and Zero Trust has been an internal initiative in the House for a couple years now.
The fact that almost no one on this thead knows these (imo overused) terms and design patterns highlights one of the various major gaps in Software Dev I've been observing for several years now - especially the North American market (given the hours that this was posted). The inability to incorporate or understand some basic security architectures is a major gap.
Edit: Keep pushing the downvotes. The truth hurts, and plays a role in jobs leaving, and funds like my employer funding cybersecurity startups in Israel, India, and Eastern Europe because the ecosystem doesn't exist in the US anymore. A similar trend happened in data layer related work.
We don't need more SKLearn plumbers calling themselves "ML Engineers" or Angular monkeys calling themselves "Fullstack Engineers" - we need people who truly understand fundamentals (or - shudders - first principles), be they mathematical (optimization), systems (virtualization), or algorithms (efficient data structures)
Its not that they aren't known, but rather we just came off a long trend of thin-clients and cloud storage. Some companies merely stay in that ethereal space, while others had concerns about their data. Criticizing people for doing what experts were pushing for the past 20 years doesn't need to devolve into calling their expertise into question.
The downvotes are for that, not because "you're wrong".
My original comment is mostly saying that it is too critical of staff saying "how did they not know" when we're now starting to return to in-house solutions. The prior solution was "Go Cloud", now its "Stay Home". In a decade, once enough people learn the struggles of having everything in-house, the next solution will be "Go Cloud" again, or whatever the future equivalent is.
The overall purpose of my comment was more akin to "calm down, we're just in a new tech cycle, no one's an idiot for following the last cycle's solution".
Maybe a significant portion of the HN base simply never worked with companies that either sold to or were a part of regulated industries, but I do not buy that.
Furthermore, all of the design patterns I am describing can and have be implemented within cloud environments as well.

Or maybe that Microsoft pays more than Meta.
