We are exited to announce the launch of hestIA, an enterprise AI assistant designed for organisations that require sovereign, auditable, and access-controlled AI capabilities without relying on external providers.
The name hestIA is drawn from Hestia, the Greek goddess of the hearth. Revered for the goodness of her modest nature and her role as the guardian of the sacred flame, Hestia symbolises a place of safety, stewardship, and trust. In the same spirit, our platform is designed to keep your organisational activities securely within our infrastructure—effectively keeping your work “in our home,” where your data is protected, managed, and always under your control.
hestIA provides a familiar conversational interface — comparable to ChatGPT or Microsoft Copilot — available today as a service hosted on Luxembourg-based infrastructure operated by itrust consulting. Unlike general-purpose AI services, hestIA does not transmit data to external AI providers: all model inference is performed on itrust consulting’s own systems.
Beyond general-purpose AI capabilities, hestIA allows organisations to build and maintain structured document collections that the system queries using retrieval-augmented generation (RAG). Responses are grounded in the organisation’s own documents and include inline citations, giving users a clear and verifiable link between answers and their sources.
hestIA is hosted on Luxembourg-based infrastructure within the European Union. All processing — model inference, document indexing, and query handling — is performed on itrust consulting’s own systems. No data is transmitted to external AI providers, making hestIA designed to support GDPR compliance for organisations processing data within the EU. Organisations using the service beyond the evaluation phase are governed by a Data Processing Agreement (DPA) with itrust consulting, establishing a clear and auditable data processing relationship.
Organisations can create and manage document collections covering any domain of activity. When users pose questions, hestIA retrieves relevant passages from those collections and returns answers with direct citations to the source documents. Supported file formats include PDF, DOCX, XLSX/XLSM, PPTX, TXT, and CSV.
Access to documents is enforced automatically at query time based on classification levels aligned with the organisation’s own information governance policies — such as public, internal, confidential, or restricted. Knowledge bases can be shared with partner organisations or other tenants, enabling controlled cross-organisational knowledge exchange while retaining full authority.
The service operates in French, German, and English. Users can interact with hestIA in their preferred language, and document collections can be organised by language to ensure queries are matched against the appropriate content. A full audit trail records all activity, supporting accountability and oversight requirements.
hestIA is live today. Organisations can register for immediate access to the platform for testing and evaluation purposes. Formal use is governed by a Data Processing Agreement (DPA) available upon request. For enquiries, contact info@itrust.lu.
The source code of hestIA will be made publicly available in the near future, allowing any organisation to self-host the platform independently.
The following capabilities are planned for future releases:
Asset inventory management: ISO 55000:2024 and ISO/IEC 27001 aligned taxonomy and ontology enabling asset classification, coherence verification, inventory validation, and lifecycle tracking
Document generation pipeline: efficient production of administrative documents from approved templates and the organisation’s knowledge base
Audit assistance agent: AI-assisted auditing against configurable standards and frameworks, covering gap identification, non-compliance detection, and mitigation suggestions
