Slack Enterprise Connector for eDiscovery & Data Collection
Collect Slack messages, channels, files, and metadata for eDiscovery, compliance, and investigations, without waiting on IT. The Onna + Slack Enterprise Connector lets you access data across your organization on a defensible, unified platform.
Why Connect Slack to Your eDiscovery Collections Platform
Slack is where critical business communication happens: decisions, file sharing, and team collaboration. When legal or compliance needs arise, that data has to be accessible, complete, and defensible.
Without the right tools, collecting from Slack is harder than it should be because:
Conversations happen across channels, direct messages, and group chats
Files and attachments are constantly shared
Edits and deletions
may occur
New workspaces and users are frequently added
The Onna + Slack Enterprise Connector enables organizations to collect this data in a defensible and scalable way. Through Slack’s Discovery API, the connector extracts messages, files, and metadata across workspaces while preserving conversation context and activity history.
Slack Connector Capabilities
The Onna + Slack Enterprise Connector is designed for enterprise-scale data collection. Key capabilities include:
Secure authorized connection
Identity mapping for Slack users
Audit logs for all collection activity
Full workspace archive support
Custodian-based data collections
Continuous sync of new users and channels
Resumable sync for large environments
In-place preservation for legal holds
File version tracking and metadata preservation
These capabilities allow organizations to perform targeted collections or maintain ongoing compliance archives across Slack environments.

Slack Metadata Collected
Along with standard file metadata such as filename and size, the connector collects Slack-specific metadata fields including:
Workspace ID and workspace name
Conversation ID and conversation name
Conversation type (channel, group, or DM)
Message ID and author
Timestamp of each message
Reaction history
Huddle call timestamps and participants
Huddle call timestamps and participants
This metadata allows teams to reconstruct communication timelines and identify key participants in Slack conversations.
