# Encrypted storage

Although blockchain certifies data integrity, data must be stored securely once collected by the CONNECTIFY platform. Our solution offers great flexibility on the underlying storage architecture, to meet customers' specific confidentiality needs. Data can be persistently encrypted in a highly secure public cloud, or on a private cloud controlled by the customer. For cases requiring total control, data remains on on-site servers, with encryption keys controlled by the customer. In all cases, data is encrypted end-to-end. Only services authorized by the customer can access decrypted data, thanks to fine-tuned management of access rights. This flexibility of data storage offers a perfect balance between sovereignty, security and ease of implementation. The customer retains full control over the lifecycle of his data.
