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.
