OverviewSuggest Edit

NuCypher is a security and encryption platform for distributed systems, including big data, cloud, blockchain, and IoT. The Company's platform offers data-centric encryption designed to enable inter- and cross-organizational granular sharing of data in a secure and auditable way based on existing AD, LDAP, and Kerberos access policies. By embedding access policies directly into encryption, NuCypher’s data-centric encryption follows data wherever it goes: across platforms (Hadoop, Kafka, Spark) and between on-premise and cloud environments.

NuCypher intends to help companies bring big data projects into compliance with internal security policies and regulatory requirements.
