France DGSI to Replace Palantir With ChapsVision ArgonOS

France’s domestic intelligence agency, the Direction Générale de la Sécurité Intérieure (DGSI), is replacing its data analysis software from U.S.-based Palantir Technologies with a domestic alternative called ArgonOS, developed by French company ChapsVision (Berthelot, 2026; EUToday Correspondents, 2026). The transition is part of a broader French government initiative to reduce reliance on foreign technology and build sovereign artificial intelligence and data infrastructure (AFP, 2026).

The decision to transition to ArgonOS was announced by French Prime Minister Sébastien Lecornu on June 16, 2026 (Berthelot, 2026). Lecornu stated that France must avoid “strategic dependencies” in the digital sphere and should not rely on tools developed by foreign powers (Leonard, 2026). The announcement coincided with the government pledging an additional €655 million in funding for domestic AI development, which includes deploying an AI assistant powered by French startup Mistral AI for civil servants (Stanciuc, 2026; Ynet News, 2026). The move followed a decision by the United States to restrict foreign access to Anthropic’s Fable AI model, an event Lecornu cited as demonstrating the risk of relying on partners capable of cutting off access to technology (AFP, 2026; AI Weekly, 2026).

The DGSI has utilized Palantir’s Gotham platform since 2016, initially adopting it following the November 2015 terrorist attacks in Paris to process intelligence data (Ynet News, 2026). At the time, French officials described the use of the U.S. system as a temporary measure until a domestic solution was viable (Ynet News, 2026). In December 2025, Palantir announced a three-year renewal of its contract with the DGSI (Palantir Technologies, 2025). Palantir has confirmed that this renewed contract remains in force and its tools will continue to be used during the transition period to ChapsVision’s system, a process expected to take several years to complete without disrupting operations (EUToday Correspondents, 2026; Ynet News, 2026).

ChapsVision, founded in 2019 by entrepreneur Olivier Dellenbach, developed the ArgonOS platform to process and analyze massive quantities of heterogeneous data (Stanciuc, 2026; ChapsVision, 2026). The company participated in a competitive dialogue launched by the DGSI in 2021 for the OTDH project (Outil de Traitement des Données Hétérogènes). ChapsVision won the first lot for data preparation in late 2024 and the second lot for data modeling and visualization in June 2026 (ChapsVision, 2026). The company reported revenue of approximately €200 million in 2025 (Ynet News, 2026).

The French transition mirrors similar procurement decisions in other European nations. In May 2026, Germany’s domestic intelligence agency, the Federal Office for the Protection of the Constitution (BfV), also selected ChapsVision’s ArgonOS over Palantir software (Schlung, 2026). The BfV decision was reported by German media outlets WDR, NDR, and Süddeutsche Zeitung, and BfV President Sinan Selen had stated in December 2025 that his agency intended to rely on European alternatives to Palantir (Schlung, 2026). Full deployment of ArgonOS at the BfV is contingent on passage of a planned German intelligence-law reform that would expand the agency’s digital powers and revise data retention rules (Schlung, 2026).

In the United Kingdom, the government has been reviewing a £330 million NHS contract with Palantir following concerns raised by members of parliament and patient groups over access to identifiable patient data (Leonard, 2026). London’s mayor also blocked a proposed partnership between Palantir and the Metropolitan Police on procurement and value-for-money grounds (Ynet News, 2026). The UK Parliament’s Science, Innovation and Technology Committee stated that reliance on a small number of U.S.-based providers represents “a clear vulnerability” that could leave public services “at the mercy of foreign actors” (AFP, 2026).
