The Spanish government has blacklisted US data analytics firm Palantir Technologies from public and private state-controlled companies due to concerns over the potential misuse of classified national security information. The decision affects major entities responsible for high-level state communications and military intelligence. Palantir continues to maintain active contracts with the Spanish Ministry of Defense, but the government has yet to decide on renewing a contract set to expire in November. The move is part of a broader effort to preserve national data sovereignty and reduce reliance on foreign defense software.
