CipherCloud and the Cloud Security Alliance (CSA) are forming a Cloud Security Open API Working Group to jointly define protocols and best practices for implementing cloud data security as a part of the cloud access security broker (CASB) framework.
The Cloud Security Alliance is an industry coalition for promoting best practices for providing security assurance within cloud computing. CipherCloud offers an open platform for cloud application discovery and risk assessment, data protection – searchable strong encryption, tokenization, data loss prevention, key management and malware detection – along with user activity and anomaly monitoring services.

In this video, Chenxi Wang talks about the need for cloud security open APIs as a means to govern how data is accessed, classified and protected within cloud applications. The reason for cloud security open APIs is that everyone will benefit by a wider pool of contributors.
