CipherStash is a data security company focused on encryption-in-use technologies that enable organizations to protect sensitive data stored in databases while maintaining the ability to query and use that data. The company develops tools and products designed to make cryptographic data protection accessible to engineers, SREs, and data scientists without requiring deep expertise in cryptography. Their core approach centers on encryption-in-use, which keeps sensitive data encrypted at all times—including when stored in databases—as opposed to only encrypting data in transit or at rest. A key element of their methodology involves envelope encryption combined with centralized key management, which enables organizations to log all data access events (recording what data was accessed, when, and by whom) and enforce least-privilege access controls at the data level, separate from infrastructure-level access. CipherStash targets organizations that handle regulated or sensitive personal data, including those in industries such as healthcare and telecommunications. Their philosophy emphasizes that data security should be resilient by design, so that a single misconfiguration or human error does not result in mass data exposure. The company is headquartered in Australia and operates as a fully remote team of 18 people distributed across Australia, the United States, the United Kingdom, Japan, and Malaysia. CipherStash has raised funding from investors including Airtree Ventures, Nexus Venture Partners, Black Nova, Sixthirty, Skip Capital, and Hack VC, including a reported $4.8 million raise in 2023.
