Why Slack security

The risks Slack won't fix for you.

Secrets in public channels

Credentials and sensitive data pasted into broadly-accessible channels are searchable and long-lived.

External & Connect exposure

Slack Connect and guest access extend your workspace to outside organizations, often without review.

Over-scoped apps & tokens

Bots, apps and tokens with broad scopes become a standing data-access path no one audits.
