Frequently Asked Questions
Clear Answers on Sovereign IT & AI Compliance
Everything you need to know about our data sovereignty engineering, on-premise AI deployments, transparent pricing, and South Orange County service radius.
What is Sovereign Infrastructure & how does it replace recurring SaaS?
Sovereign infrastructure replaces expensive, per-seat SaaS subscriptions (such as Salesforce, Slack, cloud storage, and proprietary automation tools) with self-hosted, enterprise-grade open-source platforms and dedicated hardware. You retain 100% legal ownership of your data, eliminate vendor lock-in, and cut recurring software overhead by 60% to 80%.
How does local AI comply with California State Bar Rule 1.6 & HIPAA?
Public cloud LLMs (such as ChatGPT, Claude, and Copilot) transmit your sensitive legal documents, client communications, or Protected Health Information (PHI) over third-party servers where terms of service often allow model retraining. By hosting open-weights models (like Llama 3 or Mistral) on dedicated, on-premise GPU clusters inside your physical facility, data never crosses external networks—physically preventing data leaks and maintaining absolute confidentiality.
What is your pricing model and fee structure?
We provide transparent, milestone-based pricing without predatory recurring licensing fees. Diagnostics, hardware repairs, and residential support are billed via straightforward bench rates or flat fees. For B2B deployments (local AI servers, private clouds, and managed networks), we offer clear fixed-price proposals and predictable monthly support SLAs tailored to your team's headcount.
Which areas across Orange County do you serve on-premise?
Our engineering lab is headquartered in Aliso Viejo, California. We provide rapid dispatch, hardware deployment, and hands-on IT support across South Orange County professional clusters—including Irvine, Newport Beach, Laguna Beach, Mission Viejo, Lake Forest, Laguna Niguel, and surrounding communities.
Can our existing office workstations or servers run private AI?
In many instances, yes. We conduct a preliminary hardware audit of your existing server racks, power capacity, and PCIe lanes to determine if enterprise GPUs (such as Nvidia RTX A-series) can be retrofitted. If not, we architect and deploy a custom, whisper-quiet turnkey AI server tower ready to plug straight into your local area network.
