Confidencial is a data protection platform that secures sensitive unstructured data such as intellectual property, personally identifiable information, and protected health information across cloud, on-premises, and third-party environments. The platform uses patented selective encryption technology that encrypts specific portions of documents down to the word, paragraph, cell, or pixel level while leaving non-sensitive content accessible. The platform provides automated discovery and classification of sensitive data across multiple sources including OneDrive, Amazon S3, Azure Blob, Google Drive, Box, and on-premises servers. It supports various file formats including PDF, Word, Excel, PowerPoint, text files, and images. Confidencial offers context-preserving tokenization and selective encryption for AI workflows, enabling organizations to use enterprise documents in AI pipelines while maintaining security controls. The platform includes document sharing capabilities with encryption, watermarking, and access tracing, as well as electronic signature functionality. The solution provides continuous monitoring, compliance reporting, and policy enforcement for regulations including PII, PCI, HIPAA, and GDPR. It integrates with identity providers such as Microsoft Entra, Okta, and Ping, and operates in hybrid and multi-cloud environments. The platform is ISO/IEC 27001:2022 certified, HIPAA compliant, PCI-DSS compliant, and SOC 2 Type 2 certified. It was developed from DARPA-funded research at SRI and includes encrypted storage of backend keys with a path to post-quantum cryptography.
