OneDirectory vs Slack

OneDirectory is a web service that builds employee directories, searchable profiles, and interactive organizational charts from Microsoft Entra ID data. A one-way Microsoft 365 sync keeps profiles current. Employees can search people, roles, teams, skills, and offices, while profiles can include skills, contact details, reporting lines, assistant relationships, and dotted-line reporting. The org chart supports searchable and zoomable views, customizable layouts, and downloadable views. Profiles can start chats and calls through Microsoft Teams, Slack, Webex, or other supported messaging platforms. Authentication uses Microsoft’s identity platform with read-only, least-privilege access to Microsoft 365 profile data. OneDirectory runs on Microsoft Azure, stores data in the United States by default, and offers EU and Australia residency regions. Data is encrypted with 256-bit AES at rest and TLS 1.2 or higher in transit. Pro starts at $349 a month for up to 250 profiles, with a 14-day full-access trial.
