DialOnce's AI agents (next-generation AI chatbots), including the conversational agent, mailbot and augmented advisor, operate on a sovereign architecture hosted entirely in France. The platform relies on Scaleway, a certified sovereign cloud provider, ensuring that all data linked to your customer journeys, including intents, messages, interactions and history, remains stored and secured on French territory. All data flows, databases and environments are encrypted end to end and restricted to only what is strictly necessary. The platform also uses Mistral AI, a French sovereign model, to strengthen data control and ensure transparent processing. This architecture guarantees that your DialOnce ecosystem meets the highest standards of sovereignty, confidentiality and data governance.

DialOnce applies GDPR principles from the design stage. The platform minimises data collection, guarantees full traceability of interactions, provides transparent processing and strictly controls access rights. Exchanges between DialOnce and your internal systems are always encrypted using protocols aligned with ANSSI recommendations, including TLS, SSH, SSL and IPsec. This framework ensures that every journey powered by DialOnce benefits from a secure environment that protects personal data, reduces exposure risks and supports responsible use of AI aligned with the expectations of DPOs and CISOs.

DialOnce strengthens product reliability through continuous quality monitoring. Its AI agents rely on supervision mechanisms, automated response validation and alignment with your internal knowledge sources. The platform integrates an LLM as a Judge to reduce errors, response variability and hallucination risks. Its multi-site architecture ensures robust service continuity, with enforced encryption and tightly controlled access. When Azure OpenAI is activated, a strict zero data retention policy prevents any storage or reuse of data. Each product operates within rules defined by your business context, ensuring a reliable, controlled and predictable AI suited for environments where accuracy, security and consistency are critical.

DialOnce's ecosystem is built on a frugal, eco-designed architecture that optimises platform processing to reduce resource consumption and energy footprint. Models and workflows are calibrated to eliminate unnecessary computation while maintaining high performance. This approach is part of the company's broader CSR strategy. DialOnce holds the 2025 EcoVadis Platinum medal and has reduced its carbon footprint by 14% since 2022, despite more than 20% growth in digital activity. Continuous infrastructure optimisation enables the use of high-performance, scalable AI while maintaining strong environmental control.
