Thru Add-In for IBM Notes is a plugin that extends IBM Notes (formerly Lotus Notes) with secure, unlimited file sharing capabilities. It addresses the inherent attachment size limitations of IBM Notes by replacing standard file attachments with secure file links, routing large file transfers through the Thru platform instead of the Domino mail server. Key capabilities include: - Sending files of any size directly from within the IBM Notes interface without changing existing email workflows - Encrypting all file transfers to protect confidential data in transit - Performing antivirus scanning on transferred files - Offloading large file transfers from the Domino server to improve server performance and capacity - Setting and enforcing file transfer policy rules at the individual or IT administrator level - Controlling access to shared files via expiration dates and password authentication - Revoking access to shared content on demand - Tracking file activity including metadata such as IP address, device, and application - Replacing unsecured FTP-based file transfer processes with email-integrated secure transfers The add-in is intended for enterprise environments already using IBM Notes for internal and external communication, allowing organizations to maintain existing workflows while adding compliance-oriented security controls to file transfers.
