Australian data sovereignty for AI
Before you let any AI near your customer records, quotes or case files, you should be able to answer one question: where is my business data stored? With Zatersio the answer is simple. Every AI agent we build runs on your own servers or on Australian-resident cloud (AWS Sydney), never on US-owned consumer platforms, and your data is never used to train third-party models.

Data sovereignty means your data is subject to the laws of the country it physically sits in. The moment your records flow through a server overseas, they fall under that country's legal reach, not Australia's. For most off-the-shelf AI tools, your prompts and uploads travel to US data centres and sit under US jurisdiction before you have read the fine print.
Keeping data on Australian soil is not just a nice-to-have. It is what lets you give a clear answer to a client, an auditor or a regulator about who can access their information and under whose laws. That clarity is the whole point.
The two real options we deploy
On-premise: runs on your own servers
The AI agent lives inside your own infrastructure. Your data never leaves the building. This is the strongest position for organisations with strict confidentiality requirements or internal policies that prohibit anything leaving the network. It takes a little more to set up, and we will tell you honestly when it is worth it.
Australian-resident cloud (AWS Sydney)
Your agents run in the AWS Sydney region, so your data stays in Australia under Australian law without you having to run your own hardware. For most businesses this is the practical sweet spot: sovereign, scalable, and quick to stand up.
Your choice, either way. We do not lock you into a US-owned platform, and across both options the same rule holds: your data is never used to train third-party models.
Built to align with the Privacy Act 1988
Keeping personal information on Australian-resident infrastructure that you control makes it far easier to meet your obligations under the Privacy Act 1988 and the Australian Privacy Principles (APPs). In particular, APP 8 governs cross-border disclosure of personal information. When the data never crosses a border, that whole class of risk shrinks.
We design deployments so you remain the data controller and can document exactly where information lives and who can access it. To be clear about what we do not claim: we are not asserting HIPAA, ISO or any other formal certification. What we provide is a sovereign, transparent deployment model and the ability to answer hard questions with a straight answer.
Not legal advice. We work alongside your own compliance and legal teams to map the build to your specific obligations.
Why this matters most for regulated work
Healthcare
Patient records carry some of the strictest handling rules in the country. A sovereign deployment keeps clinical data inside your control. See how this applies on our AI for healthcare page.
Legal
Legal professional privilege does not survive a careless upload to an overseas model. Keeping matter files sovereign protects privilege. More on our AI for law firms page.
Finance
Financial and tax records demand clear residency and access controls. Sovereign deployment gives you both, with a defensible record of where the data sits.
Government
Public-sector data residency requirements rule out most consumer AI tools outright. On-premise or AWS Sydney keeps you inside the rules.
For trades and retail this is optional rather than essential, but the choice still stays yours.
How we deploy it
Zatersio is founder-led and Melbourne-based: no account managers, no offshore teams handling your data. The work is done by Lakitha Sahan, a software engineer with ten years of experience, which means the person who designs your deployment is the person who understands where every byte goes.
We start by mapping what data your AI agents will touch and your residency requirements, then recommend on-premise or AWS Sydney accordingly. Most engagements land between $2,000 and $15,000 AUD (inc. GST) depending on scope, and the sovereignty model does not carry a separate premium, it is how we build by default.

On infrastructure you control. You choose between two options: on-premise (the AI runs on your own servers, so data never leaves your building) or Australian-resident cloud on the AWS Sydney region. Either way the data stays in Australia, under Australian law. We do not route your data through US-owned consumer platforms.
No. Your data is never used to train third-party models. Whatever your agents read, write or learn from stays inside your environment and is used only to serve your business. That is a hard rule we deploy by, not an opt-in setting you have to remember to switch off.
Keeping personal information on Australian-resident infrastructure under your control makes it far easier to meet your obligations under the Privacy Act 1988 and the Australian Privacy Principles, especially APP 8 on cross-border disclosure. We design deployments so you stay the data controller and can answer 'where is the data and who can see it' with a straight answer.
We do not claim HIPAA, ISO or similar certifications, and we will not pretend to. What we offer is a sovereign deployment model: your data stays in Australia, on infrastructure you control, never used to train outside models. For regulated work we build to your internal compliance requirements and document exactly where data lives and who can access it.
It is essential if you are in healthcare, legal, finance or government, where client confidentiality and data residency are non-negotiable. For trades and retail it is optional. Either way, the choice stays yours, and we will tell you honestly when the on-premise option is worth the extra setup and when Australian cloud is plenty.
