Cloud AI is fine for a public brochure. It is the wrong default for privileged files, health records, board papers and anything a CISO will not send offshore.
On-prem means hardware you own, open-weight models, private search over your own documents, and zero egress unless you flip a switch.
Three kits
- Sovereign desk PC — 3–8 people. From A$8,400 installed, Care A$490 / month.
- Department node — shared UI, roles, audit log. From A$18,000, Care A$990 / month.
- Air-gapped / Defence-adjacent — no default internet, approved-media updates. Quoted, Care from A$1,690 / month.
Straight limits
Claude and GPT do not hand over weights for a PC in your office. On-prem is open-weight models you are allowed to host. We document controls for your assessor — we do not sell a fake IRAP sticker. We do not sell SECRET or TOP SECRET platforms.
If we put the box in, we stay on it for year one. An unpatched local model is worse than no model.
