"One of the reasons we always allowed customers to set their own encryption keys was so even if someone came knocking we truly couldn’t help," the cloud backup executive said. "In theory, yes, with the proper court order, we would’ve had to have turned over data. if we didn’t hold the encryption key, there's nothing we could do. I suppose the government could’ve gone after the customer for the key and us for the encrypted data."
"The company is making its new encryption system available this week in the SIRIS solution. It’s designed so that only the MSP or customer holds the decryption key. And since Datto doesn’t have this key, Datto cannot turn it over to the U.S. National Security Administration (NSA), even if ordered by a court of law."
Cloud Services, Backup and Blind Subpoenas
Legal experts also suggest that MSPs become familiar with so-called blind subpoenas. To paraphrase Data on the Edge:"Let’s assume an MSP (Data Controller) stores the data of its customers (Data Subjects) with a cloud service provider (Data Processor). Then, assume a blind subpoena is served on the Data Processor (the CSP) without notice to the Data Controller (MSP) or the Data Subject (End Customer). The Data Controller and/or Data Subject do not and may never have an opportunity to object or move to quash the subpoena. And most importantly, the Data Processor may be forbidden to notify the Data Controller or Subject of subpoena service."
