Files are uploaded to our servers using Secure Socket Layer (SSL) or Transport Layer Security (TLS) and are saved with 256-bit AES encryption. These are the same encryption protocols used by Online Banking Services, Online Retailers such as Amazon, and websites like Facebook and Google. Each file saved in our system has a unique encryption key. When a file is uploaded, it is encrypted before being copied to its permanent storage location. Downloaded files are decrypted before their contents are sent to their recipients. The file encryption keys are not stored on the same server with the files themselves, ensuring that someone with physical access to our storage servers has no access to the files contained on their hard drives.
