Aware - Slack Canvas & List Ingestion - Mar 2026

Service Update

Availability	March 17th, 2026
Product(s)	Aware
Who's affected	Administrators & End Users

Overview

Mimecast is pleased to announce that Aware now supports the ingestion of Slack Canvases and Lists. When a Canvas or List is shared as an attachment in a Slack channel, Aware will automatically ingest and process it.

All existing Aware file compatibilities apply to Canvases and Lists, including search, analytics, and compliance coverage.

What's changing

• Search & Discovery: Canvas and List content is fully indexed and searchable within Search & Discover, alongside your existing Slack files and messages.
• Compliance & Retention: Canvases and Lists are subject to the same retention policies and compliance controls as other files in your Aware workspace. This ensures consistent coverage across all Slack content types.
• Analytics: Activity associated with shared Canvases and Lists is reflected in your Aware analytics dashboards. Canvases shared in channels are also captured in Signal, providing visibility into how and where Canvas content is being distributed across your workspace.

Recommended actions

Nothing needs to be done as a result of these changes. Coverage begins automatically as Canvases and Lists are shared in your Slack channels.
