Zeutro LLC develops encryption and data security technology. The firm's technology secures existing web and cloud-based applications, enabling migrating applications from private clouds to public cloud technology without loss of security. The company utilizes Attribute Based Encryption, which can embed any access predicate into the ciphertext itself, making data access self-enforcing through cryptography. The company's primary platform is Arethusa, an advanced data protection and key management system for encrypting enterprise data-at-rest. The benefits of this technology include: easy integration with existing AES-based solutions, protecting data stored in a public, untrusted cloud from unauthorized access, prevention of collusion attacks, and enabling secure offline access.
