Nightfall AI integrations

Nightfall AI connects through APIs to the SaaS tools where sensitive data often spreads. Supported apps include Slack, Google Drive, Gmail, Jira, Confluence, Salesforce, Notion, and Zendesk, along with Microsoft Teams, OneDrive, Exchange Online, and SharePoint Online. It also covers endpoints and browsers, monitoring clipboard use, USB transfers, and local uploads.
