Our secure messaging app is purpose-built for board members and executives who demand both confidentiality and compliance. This isn’t just another messaging tool — it is an integrated extension of our Diligent Borads platform, enabling direct communication within the same closed loop environment where board materials are shared and discussed. Absolute Peace of Mind. Whether you're discussing mergers, financials, or strategic moves, our app ensures your conversations stay private — protected by best-in-class systems infrastructure, message encryption and strict access controls. Every message lives within the governance framework you already trust — ensuring alignment, compliance, and continuity. Your trusted support by your side. Diligent Messenger is built to reflect the real-world dynamics of board operations, offering two distinct user roles: Admins and Board Members/Executives. Admins can create groups, share announcements, and control permissions centrally, without intruding on private board discussions. It’s the same trusted support board administrators provide in person, now extended into a secure digital environment. Additional information: Over 4,000 organizations and 145,000 executives and board members trust Diligent with their most confidential board meeting materials. Now, we’re bringing that same level of protection to your most time-sensitive and critical messages. In order for you to begin using Diligent Messenger for secure business messaging, an account and administrator will need to be set up for your organization.
