Cosmian provides a comprehensive data protection suite powered by advanced cryptography to secure data in public cloud environments. The company's offerings center around three main components: a centralized Key Management System (KMS) for managing encryption/decryption processes, keys, and certificates across organizations; verifiable confidential virtual machines that enable secure deployment of sensitive applications in public cloud infrastructure; and post-quantum encryption libraries that include encrypted access policies and encrypted data search capabilities. The company's technology enables organizations to send only encrypted data to cloud operators, deploy sensitive applications in public cloud environments with cryptographic verifiability, and protect server secrets against theft. Cosmian's solutions support confidential computing use cases, including a 100% confidential AI runner that allows organizations to deploy, query, and fine-tune AI models while maintaining encryption throughout the process. Cosmian's products are available on major cloud marketplaces including AWS, Azure, and Google Cloud. The company serves various use cases including workplace application security, AI security, third-party SaaS data protection, cloud migration security, and data lake protection. Their encryption libraries feature post-quantum resistance to address future cryptographic threats. Cosmian works with academic partners including ENS, CNRS, and INRIA, and maintains technology partnerships with major cloud providers and hardware manufacturers. The company's covercrypt technology has achieved ETSI standardization for post-quantum data protection.
