Own Your Data
Keep your organization's communication and files within infrastructure you control.
SHACK — Self Hosted Actions, Collaboration, and Knowledge-base
Secure team communication you own.
Shack Messenger gives organizations a private, secure space for team communication and collaboration — with control over where their data lives and how it is managed.
Deploy it on your own infrastructure or use a private dedicated environment hosted exclusively for your organization.
Your messages. Your files. Your calls. Your control.
Why Shack?
Private Communication
End-to-end encrypted voice, video, and screen sharing for private conversations and collaboration.
Built for Organizational Control
Audit logs, two-step sign-in, SSO, IP restrictions, and access history help organizations maintain control over their communication environment.
