SaaS-based secure file-sharing startup Sookasa, based in San Mateo, Calif., encrypts data in Dropbox, Gmail and other cloud services popular with end users. The firm said it encrypts data before files are shared to help businesses meet regulatory mandates, such as HIPAA and FERPA. It also encrypts the information in transit and creates a folder to synchronize files across all the data owner's devices. Sookasa also monitors files and keeps an audit trail on file-sharing activity. The Israeli startup's co-founder and CEO Asaf Cidon formerly worked as an engineer in Google's Web search arm.
