You can empower your team with lightning-fast full-text searches for emails and attachments, accessible directly through Outlook or a web browser. Whether you use Microsoft 365, Google Workspace, or an on-premise Exchange server, the software integrates into your existing environment. It is specifically designed for small and medium-sized businesses looking for a reliable way to prevent data loss and simplify backup processes.
