Private AI: Sovereign, Controlled, Secure

Public AI services are the right solution for most organisations. But for some, the requirements are different.

Large enterprises with strict data sovereignty requirements, Australian government agencies operating at PROTECTED or above, defence contractors with DISP obligations, healthcare organisations handling sensitive clinical data, and financial institutions with regulatory data residency requirements may need AI capability that stays entirely within their own controlled environment.

Evocate helps these organisations plan and implement private AI infrastructure, bringing large language model capability in-house, on Australian soil, within environments they control.

Private AI Infrastructure Consulting Australia

Infrastructure assessment

Infrastructure Assessment and Planning

We assess your current data centre or private cloud environment against the compute, storage, networking and cooling requirements of large language model workloads. AI inference workloads are GPU-intensive. Planning the right hardware and infrastructure configuration upfront avoids costly rework. We help organisations understand the realistic costs and complexity of private AI infrastructure, and where a hybrid approach (private for sensitive workloads, cloud for general workloads) may be more practical.
LLM model selection

Model Selection and Deployment

The private AI market has matured significantly. Open-weight models such as Meta’s Llama series, Mistral, and Microsoft Phi are deployable on private infrastructure with performance that is suitable for many enterprise use cases. We help organisations select the right model for their use case, performance requirements and hardware constraints. We deploy and configure model serving infrastructure using frameworks such as Ollama, vLLM and Azure Arc for on-premise AI, creating endpoints that can be consumed by enterprise applications in the same way as cloud AI APIs.
Business systems integration

Integration with Business Systems

Private AI infrastructure is only valuable when it is connected to the data and applications your organisation uses. We integrate private AI endpoints with SharePoint, business applications, document management systems and workflow platforms, enabling AI-powered search, summarisation, drafting and automation that operates entirely within your environment.
Security and access controls

Security and Access Controls

We implement role-based access, network segmentation, audit logging and monitoring for private AI infrastructure, ensuring that AI capability is available to authorised users and auditable for compliance purposes.
Operational support

Operational Support and Maintenance

Private AI infrastructure requires ongoing maintenance: model updates, performance monitoring, capacity management and security patching. We can provide managed services support for private AI environments, or train your team to manage them.

Why Some Organisations Need Private AI

Several scenarios drive the need for private AI infrastructure:

Data Sovereignty

Organisations that cannot send data to external AI services regardless of contractual protections: certain government agencies and intelligence-adjacent contractors.

Regulatory Compliance

Healthcare, financial and legal data subject to regulations that restrict where it can be processed.

Security Classification

Organisations working with classified information that cannot process data through public APIs.

Model Control

Organisations needing to control which AI models are used, how they are updated, and what data they have been trained on.

Latency & Reliability

High-volume AI workloads or latency-sensitive applications where private infrastructure is more performant.

Frequently Asked Questions

Meaningful LLM inference requires GPU hardware. For smaller open-weight models (7B-13B parameters), modern enterprise GPU servers (such as NVIDIA A-series or H-series) provide suitable performance. Larger models (70B+ parameters) require multi-GPU configurations. We assess your target use case and recommend hardware accordingly.
Open-weight models have improved significantly. For many enterprise use cases (document summarisation, question answering over internal knowledge, structured data extraction) modern open-weight models perform comparably to commercial models when correctly configured. For tasks requiring the highest level of general reasoning, cloud models currently have an advantage, which is why many organisations use a hybrid approach.
It depends on usage volume and data sensitivity requirements. For high-volume AI workloads where data sensitivity makes cloud unsuitable, private infrastructure can be cost-effective. For lower-volume workloads, cloud AI is typically more economical. We help organisations model both options.
Evocate has experience with Australian government environments and understands the requirements of PROTECTED-level deployments including the ISM controls and Microsoft’s Australian government cloud. We can help organisations assess whether private infrastructure or the Microsoft government cloud region is the appropriate solution for their classification requirements.
