Federated Communications
You set up federated communications by linking trust rules between separate identity and chat domains. This setup lets users talk and share work across teams without new guest accounts.

You set up federated communications by linking trust rules between separate identity and chat domains. This setup lets users talk and share work across teams without new guest accounts. Most teams start by exchanging domain keys and mapping high-level user groups. Still, broad group rules often grant outside users too much power inside internal systems.
How federated communications work in practice
In a standard setup, each company runs its own home server and identity store. You link two domains by sharing public keys and trust certificates between both servers. When a user sends a message or request, their home server signs that payload. The receiving server checks the signature against the trusted domain list before delivery.
Admins also map external identity claims to local roles inside their own system. You pick which partner domains can join channels, trigger bots, or read shared data. The local system trusts the partner server to verify the user login state. Once the handshake passes, the user interacts with shared resources using that mapped role.
What domain trust solves and what it misses
Domain federation removes the need to manage passwords for partner users and contractors. When a partner leaves their company, their home admin disables their primary account. That change stops their access to your federated channels right away. You also keep your own login rules and multi-factor checks on your side.
Still, domain trust only checks who logs in at the start of a session. It does not inspect what individual commands, queries, or chat ops requests do in flight. If a federated channel runs an ops bot, partner users might trigger database queries. Native trust rules cannot block a bad query or mask card numbers in responses.
Securing shared workflows and data
Teams often connect chat channels and ticket tools to internal databases and servers. When you add federated communications to these channels, external users gain indirect system reach. A broad role assigned to a partner domain applies to every action they take. You cannot restrict a single dangerous command using standard domain trust settings alone.

To stay safe, you must check every request at the action level, not login. Teams need controls that inspect each command before it reaches the database or server. You also need data masking that rewrites emails and phone numbers in returned results. This keeps sensitive records safe even when partner users share the same workspace.
Add runtime guardrails and masking beside your databases and APIs
Login rules, role grants, and CI checks govern who connects to your stack. Yet any allowed script, engineer, or AI agent still runs commands with the full scope of its role. For workloads on Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes, SSH, or internal HTTP services, hoop.dev sits beside the service as an open-source proxy, a sidecar for your database or API.
Before a query runs, hoop.dev guardrails check the statement against your rules. An AI Analyzer you configure can score intent or hold risky calls for human review. Next, hoop.dev data masking rewrites sensitive fields in responses, and each verdict is logged per listener. Explore the MIT-licensed project on GitHub.
Frequently asked questions
What is the difference between guest accounts and federated communications?
Guest accounts live inside your own identity store and need manual lifecycle updates. Federated communications let users keep their home accounts while your server checks domain trust.
How do you revoke access for a federated partner domain?
You remove the partner domain from your allowlist and delete their public trust key. This action drops all active links from that company across your workspace right away.
Why are chat bots risky in federated channels?
Many bots run with one static high-level key to talk to internal databases. External users in shared channels can prompt those bots to read or change data.
Teams that document these role rules and review logs each month catch config drift early. Clear ownership for each role keeps live systems simple to run and easy to audit across the whole team.
