MongoDB has introduced new capabilities to its Queryable Encryption feature, now supporting prefix, suffix, and substring queries in public preview, which allows secure expressive searches on encrypted data without modifications to application code. This advancement is aimed at enhancing data protection, simplifying compliance, and eliminating the need for complex workarounds, thereby enabling organizations to perform partial-match searches on encrypted sensitive information, such as names or IDs, without exposing the underlying data. The technology is available at no extra cost across MongoDB Atlas, Enterprise Advanced, and Community Edition, and is designed to meet the demands of modern applications by ensuring data security across its lifecycle. Additionally, MongoDB is integrating full-text and vector search capabilities into its Community Edition and Enterprise Server, allowing developers to build sophisticated search features without the need for external systems, thereby simplifying architecture and reducing operational overhead. Meanwhile, MongoDB has announced a leadership transition, with Chirantan “CJ” Desai set to replace Dev Ittycheria as CEO on November 10, 2025, as the company prepares for its next phase of growth, focusing on leveraging AI and data-intensive applications.
