Data security company Gazzang announced the immediate availability of Gazzang CloudEncrypt, which provides data encryption and key management throughout the Amazon Elastic MapReduce data lifecycle.

CloudEncrypt was developed to meet the needs of enterprises looking for data security for their Amazon EMR projects, Gazzang says.

The product is designed to help organizations utilize big data in the cloud by securing data in-flight and at-rest within burstable Amazon EMR environments, while enabling companies to maintain control of their encryption keys, and separate them from the data itself.

With CloudEncrypt, data in the cloud remains encrypted and indecipherable to users and applications that have not been given explicit access, including the cloud infrastructure provider. 

Key features include automated, scalable deployment of Gazzang zNcrypt on Amazon EC2 instances, ensuring encryption of data as it is written to the nodes for processing; Hadoop integration with encrypted Amazon S3 data; and encryption of the resulting data for transfer back to the client data center.

"Large-scale encryption and key management has been one of the holy grails of security for decades," Wendy Nather, research director of enterprise security at 451 Research, said in a statement. "The challenge has gotten even bigger with the rise of big data and the dynamic cloud. Enterprises need to solve the problems of dynamic encryption and cross-border data compliance in order to take full advantage of these new technologies."
