About Whaller

Whaller — Sovereign Collaboration for Organisations That Cannot Afford Compromise Founded in Paris in 2013, Whaller is a French collaborative platform developed, hosted and governed entirely in France, with 100% French capital and no dependency on non-European actors. Its infrastructure runs on OVHcloud within French data centres, under French and European law exclusively. In a world where the US Cloud Act and FISA can compel any American company to hand over data stored anywhere in the world, this independence carries concrete operational value. Not a marketing argument — a structural guarantee. The platform is built around one core principle: the sphere. Each sphere is a sealed, independent collaborative space for a specific team, project or use case. No data from one sphere can be accessed from another without explicit authorisation. This compartmentalisation is architectural, not organisational — dramatically reducing the risk of data leaks, misdirected communications and lateral propagation during a security incident. Whaller — The Digital Workplace Whaller's core platform delivers a complete sovereign digital workplace: secure messaging, file storage and co-editing with Microsoft Office compatibility, task management via Kanban boards, shared calendars, video conferencing, internal surveys, a customisable intranet portal and a role-based member directory. Available on desktop and mobile, with a white-label option for fully branded deployments. Whaller reduces internal email volume by up to 40%, replacing scattered exchanges with structured, persistent spaces where information lives in context rather than in individual inboxes. Whaller DONJON — SecNumCloud 3.2 Whaller DONJON is the flagship solution for organisations handling sensitive data that cannot tolerate grey areas in their security chain. It is the first and only French collaborative SaaS platform to hold SecNumCloud 3.2 qualification from ANSSI — the most demanding cloud security standard in France, covering more than 360 requirements across 14 thematic areas. The qualification applies to both layers: infrastructure (IaaS OVHcloud) and application software (SaaS Whaller DONJON). This eliminates the grey zone common in competing offerings, where a certified infrastructure hosts non-certified software. The chain of trust is complete. Whaller DONJON is designed for ministries, operators of vital importance, NIS2 essential and important entities, healthcare institutions, defence organisations, DORA-regulated financial sector operators, and large private groups seeking a dedicated sovereign space for board and executive committee exchanges. Key capabilities include end-to-end encrypted spheres via Cryptoner technology, passwordless strong authentication with multifactor biometrics via the AuthSezam partnership, digital document watermarking with WaToo to identify the precise origin of any information leak, comprehensive access logging for audit and regulatory compliance, and physically dedicated hosting per client with no data pooling between organisations. Whaller RÉSILIENCE — Communicating When Everything Else Fails Whaller RÉSILIENCE answers one question every business continuity manager should have already resolved: if the primary infrastructure is hit by ransomware tomorrow morning, how do teams coordinate? Not with the tools that have just been encrypted. Whaller RÉSILIENCE is a secure crisis communication channel, permanently available and activable within minutes, entirely isolated from the organisation's usual information system. Pre-configured during calm periods and kept in permanent readiness, it provides sealed spaces, file sharing, video conferencing and event management from the first minutes of an incident — integrating directly into Business Continuity and Disaster Recovery Plans. Whaller (IA)ssistant — Sovereign Generative AI Whaller (IA)ssistant integrates generative AI into the platform without data leaving the organisation's sovereign environment. Built on open-source models hosted by OVHcloud on French infrastructure, it summarises exchanges, generates tasks, drafts communications and automates routine content production — with full GDPR compliance. No data is used for model training. No queries exploited for secondary purposes. Whaller's MCP server further allows AI assistants and automation platforms to interact with the platform in real time while preserving complete data sovereignty. The Whaller Commitment Member of the Pôle d'Excellence Cyber, holder of the Cybersecurity Made in Europe label, and the first collaborative platform to achieve SecNumCloud qualification — Whaller has embedded sovereignty into its architecture from day one, not as a feature, but as a founding constraint.
