About Seald

Seald is a cloud data security software from Seald that ensures the highest level of end-to-end encryption and data security. It provides industry-leading encryption, quick integration capabilities, and support for various industries, so application developers can secure sensitive data with ease. Seald is designed specifically for developers, allowing them to incorporate reliable encryption without managing the underlying complexities. This solution is suitable for sectors like healthcare, legal, and insurance, ensuring compliance and protection of sensitive information. Key capabilities: end-to-end encryption quick integration multi-industry support compliance assistance data protection Best for: application developers that need to secure sensitive cloud data.

Seald is a comprehensive and developer-friendly software development kit (SDK) designed to seamlessly integrate state-of-the-art end-to-end encryption into any web or mobile application. Its primary purpose is to secure sensitive cloud data by abstracting the complexities of cryptography and key management, allowing developers to implement the highest level of data security with minimal effort. At its core, Seald's functionality is built on a zero-trust architecture, which means no server—not even Seald's—is inherently trusted. The confidentiality of encrypted data remains assured even in the event of a breach of server infrastructure, protecting data from unauthorized access by hackers, malicious insiders, or government officials. Key features that distinguish Seald include its robust "2-man-rule" recovery mechanism, which allows users to recover their private keys without creating a security backdoor, and its "Sig-Chain" technology, which prevents man-in-the-middle attacks by verifying a user's public keys. This comprehensive approach ensures that data is protected throughout its entire lifecycle, from the moment it's created on a client device to when it's stored and processed by backend systems.
