Air-gap, hosting in France, HDS: deploying compliance AI in the most sensitive environments

In brief.
For most organisations, the sovereign cloud is enough. For defence, healthcare or the public sector, a shared AI is disqualified from the outset, whatever its technical quality. Three deployment levels (sovereign SaaS, private cloud, disconnected on-premise) meet different levels of sensitivity.

For most organisations, the sovereign cloud is enough. For some (defence, healthcare, critical operators), the data simply cannot leave. Here is how AI gets deployed there all the same.

Not all data is equal. For many organisations, controlled European hosting fully meets confidentiality and compliance requirements. But there is a category of organisations for whom the bar is radically higher: defence and sovereignty industries, healthcare institutions handling patient data, operators of vital importance, sensitive public administrations.

For these organisations, the question is not “where is my data in the cloud?” but “can my data leave my perimeter, yes or no?”. And often, the answer is no. It is precisely for these cases that Optivalue.ai offers deployment modes that most consumer AI tools cannot provide.

The problem: shared AI is structurally disqualified

A consumer AI processes your data on shared infrastructure, often outside Europe, sometimes reused to train its models. For patient data or classified information, that is simply impossible, not as a matter of preference but because of regulatory and contractual obligations.

The technical challenge is well known: large language models are so heavy that they run almost exclusively in the public cloud. That is the barrier that long kept AI out of the most closed environments. Our approach based on compact, specialised models (DSLM) removes that barrier: high-quality AI can now run without sending a single piece of data outside.

Three deployment levels, depending on your sensitivity

Optivalue.ai adapts to the level of protection your data actually requires.

Sovereign SaaS, hosted in France. For data subject to the GDPR and to standard European requirements: one private instance per client, hosted in France, never shared. For healthcare, this hosting can meet HDS requirements (Hébergeur de Données de Santé, the French health data hosting certification).

Private cloud (BYOC). The AI runs in your own cloud environment, under your control, for organisations that want to retain control of the infrastructure while benefiting from a managed deployment.

On-premise and air-gap. For the most critical data: a deployment entirely on your servers, including in an environment physically disconnected from the internet (air-gap). Your data never leaves your premises. No outbound connection, no possible leak.

In every case, the principle is the same: your data belongs exclusively to you, is never shared, and is never used to train a third-party model.

A requirement driven by your ecosystem

This capability is no longer just an internal preference. Your own customers and prime contractors (especially in defence, healthcare or critical infrastructure) now require it in their assessment questionnaires. And regulation (NIS2, DORA, GDPR, sector-specific requirements) is converging in the same direction: knowing precisely where your data is and who can access it.

Choosing an AI that can run air-gapped is therefore not only about protecting your secrets: it also means being able to answer “yes” to the sovereignty requirements your clients and regulators put to you.

Rigour, in every environment

Sovereign deployment does not come at the expense of quality. Whichever mode you choose, you get the same guarantees: 85 specialised agents, sourced answers (document, page, date), abstention when there is no evidence, an explainable confidence score, and our compliance foundation (ISO/IEC 27001, 27017, 27018, SOC 1-3, HDS). The security of the environment never degrades the reliability of the answers.

Key takeaways

For organisations handling the most sensitive data, AI should never have been a choice between performance and confidentiality. For a long time, though, that choice had to be made. That is no longer the case.

With sovereign cloud, private cloud or fully isolated deployment, Optivalue.ai brings compliance AI to places where it was previously off-limits, without ever asking your data to leave the perimeter you have chosen to defend.
