Your data. Your models. Your control.
A sovereign AI platform deployed where you choose, controlled by you throughout. Ethro-Sphere gives an enterprise its own AI — its own models, its own data, its own infrastructure, its own access controls. On-premise or in your country's cloud. Operated end-to-end by EthroCore.
The AI most organizations rely on today — public chat assistants, foreign APIs, cloud-only platforms — sends their data, their customer data, and their proprietary content to servers operated by foreign vendors, in foreign jurisdictions, governed by foreign law. This is not a misuse. It is the default behavior of the products themselves.
Every organization that has tried to ban public AI has discovered the same four facts.
Employees use it anyway.
Personal devices, personal accounts, mobile networks. The technology is too useful and too easy to reach. Bans turn into shadow IT.
Customers expect AI.
Self-service, fast answers, conversational interfaces. An organization without AI in its customer-facing surfaces is competing at a disadvantage.
Competitors are deploying it.
Whatever the regulatory posture, peers are moving. Time spent debating whether to allow AI is time the market does not give back.
The risk does not go away.
Blocking removes only the visible usage. The content already shared, the embeddings already created, the prompts already logged — those remain.
The only durable answer is to give the organization an AI it is allowed to use.
Ethro-Sphere is the platform that gives an enterprise its own AI: its own models, its own data, its own infrastructure, its own access controls. Deployed on-premise or in an in-country cloud region. Operated end-to-end by EthroCore. You license the platform and control everything that runs on it. EthroCore brings the platform, the deployment, and the people who make it work.
You choose where Ethro-Sphere runs. EthroCore deploys, configures, and maintains either path.
Inside your data center.
Deployed in your jurisdiction.
Sovereignty is a word the industry overuses. If a sovereignty claim does not contain these six concretes, it is not really sovereignty.
01
Data never leaves.
All conversations, files, and embeddings remain inside the client's deployment boundary.
02
Models run locally.
Language and embedding models execute on the client's hardware or in-country cloud, not via foreign API calls.
03
Storage is local.
Vector database, document store, logs, and audit records — all written to client-controlled infrastructure.
04
No outbound calls.
The platform does not phone home to foreign AI providers or telemetry endpoints during normal operation.
05
Client controls the keys.
Encryption keys, access policies, retention rules, and deletion authority sit with the client, not the vendor.
06
Air-gap capable.
On-premise path.
When deployed on-premise, Ethro-Sphere can run with zero outbound internet, fully isolated.
Ethro-Sphere is structured in four user-visible layers. Each layer can be operated by your team without engineering involvement.
Your content, structured for AI.
Documents, databases, mailboxes, spreadsheets, and structured records ingested into your own vector store, not a shared one. Multi-format ingestion runs continuously, with live progress visible to administrators. Includes dedicated pipelines for document text, CSV and spreadsheet data, SQL tables (single and multi-table), email and attachments, and context extracted from images and visual sources.
AI agents trained on your content.
Purpose-built conversational agents, scoped to your use cases, behaving the way you define. Agents support text chat, real-time voice, and telephony-connected calls — all running through the same platform, with full conversation continuity across channels.
Roles and groups the AI respects.
Every retrieval honors who the user is and what they are allowed to see. Group-scoped content, role-based access control, and step-up verification (OTP, KBA, proof tokens) for sensitive actions. The AI cannot leak content across organizational boundaries.
An admin console your team runs.
Upload content, define agents, manage users and groups, review every conversation and search, monitor sync jobs and system health. Day-to-day operation does not require engineering.
Ethro-Sphere hosts each of them under one platform, with shared content, shared access controls, and shared operations.
AGENT 01
Customer-facing.
Agents that answer questions for the people who buy from you — product information, support, account inquiries, transactional flows. Available in chat, voice, and over the phone.
AGENT 02
Employee-facing.
Agents that answer questions for the people who work for you — HR, IT, policy, compliance, internal services. Group-scoped so each employee sees only what they are entitled to.
AGENT 03
Knowledge.
Agents that search, summarize, and reason across your documents and structured data on demand. Source-attributed answers with full traceability back to the underlying content.
AGENT 04
Operational.
Agents that handle routine workflows — drafting, classifying, routing, validating — that today require human time and attention.
When Ethro-Sphere runs on-premise, every layer of the AI runs inside your walls. Language models, embedding models, vector database, document storage, agent runtime, admin console — all of it. Nothing crosses the boundary.
YOUR ORGANIZATION'S PERIMETER
Nothing crosses the boundary.
Vendor breach.
If a foreign AI provider is compromised, it does not affect you. You are not connected.
Internet outage.
When the link goes down, the AI does not. The stack is local.
Sensitive facilities.
Sites where public internet is not permitted still get full AI capability.
When Ethro-Sphere runs in-country, every layer of the AI runs inside your jurisdiction. Storage, processing, audit logs, model execution — all of it stays under local law. Data has no path out.
YOUR JURISDICTIONAL PERIMETER
No data egress. Anywhere.
Vendor breach.
If a foreign AI provider is compromised, it does not affect you. You are not connected.
Geopolitical change.
Sanctions, contract terminations, jurisdictional shifts — your operations are not exposed.
Regulatory continuity.
Data residency requirements, local audit obligations, compliance reviews — all served by default.
The platform is half the deliverable. The expertise is the other half. EthroCore works alongside your teams to onboard your content, define your agents, structure your intents, and translate your business processes into working AI configurations. It is what determines whether the AI delivers, not just deploys.
Built, not promised.
Operational today, with real clients running on it.
We own the stack.
Not a reseller. You are buying from the people who built it.
Sovereign by design.
On-premise and in-country deployment is the architecture, not an option bolted on.
Operated long-term.
Deploy, maintain, optimize, evolve — as a continuing relationship, not a handoff.
Present and accountable.
Same region, same time zone, same regulatory context.
Sovereignty is not a feature. It is a different posture toward the technology.
FROM
"Should we use AI?"
Renting intelligence from a foreign vendor. Hoping the data does not leak. Negotiating around what cannot be negotiated.
TO
"We have our own AI."
Controlling the intelligence layer of your organization. The data stays. The decisions stay. The capability is yours to direct.
This is the conversation Ethro-Sphere lets you have with your board.
Schedule a working session with the EthroCore team. We will walk through the platform on real content, in your context, against your specific use case.
