Sidian DataGuard is a data protection platform that prevents sensitive and privileged information from leaving regulated organizations while allowing everyday work to continue. It sits inside email, cloud storage, shared folders, and AI workflows, checking every document, attachment, message, and prompt before it moves. Rather than blocking an entire send, DataGuard applies the organization’s policy, removes only the information that should not leave, scopes content to the recipient, and records what was removed, why, and under which rule. Email & File Protection works across Outlook, Gmail, OneDrive, SharePoint, Google Drive, and Dropbox, automatically cleaning outbound content while preserving the normal workflow. Secure Sends handles large document sets from Clio, OneDrive, SharePoint, Drive, or local uploads, flags names, dates, account numbers, IDs, and other protected data, and supports bulk review, redaction, secure sharing, expiration dates, and per-recipient activity logs.
