Closed Federated Collaboration
You set up closed federated collaboration by linking trusted identity directories between specific partner companies. This setup lets approved outside users log in to shared systems without public guest links. Many teams build this trust by sharing wide roles across partner domains. Broad roles give outside partners too much reach inside your private databases and apps. A small mistake by a partner can then delete data or expose private fields.

You set up closed federated collaboration by linking trusted identity directories between specific partner companies. This setup lets approved outside users log in to shared systems without public guest links. Many teams build this trust by sharing wide roles across partner domains. Broad roles give outside partners too much reach inside your private databases and apps. A small mistake by a partner can then delete data or expose private fields.
How closed federated collaboration works in practice
In a closed federation model, two or more companies agree to trust specific identity claims. Each company keeps its own login directory to manage its own workers. Admins set up a direct trust link between the home system and the host system. They reject public sign-ups and block unknown domains by default. Only domains on an approved list can send login tokens across the boundary.
When a partner engineer needs to run a task, they log in at home first. Their home directory checks their password and second factor. Next, it sends a signed token to the host company system. The host system checks the token signature and maps the user to a local role. That local role controls which servers, databases, or tools the partner can open.
Why teams use cross-company role mapping
Before federation, teams created separate local accounts for every outside contractor or partner. Admins had to reset passwords and track when people left the partner company. Often, old accounts stayed active for months after a project ended. Federation fixes this problem because the home company controls the user lifecycle. When a worker leaves the partner firm, their home token stops working right away.
Cross-company role mapping also helps teams group external users by job function. A host admin can map a partner group to a read-only database role. Another partner group might map to a support role for a specific app. This structure keeps identity rules clean and avoids account sprawl across multiple companies.

Where native federation leaves a security gap
Native federation does a great job deciding who can log in to a host system. Still, the trust check ends as soon as the session starts. Once a partner assumes a local role, the host system trusts every action they take. Federation cannot inspect individual database queries, shell commands, or API requests in flight. A valid user with a read role can still pull huge tables of sensitive records.
Shared projects often hold customer emails, phone numbers, card numbers, and national IDs. If a partner runs a broad select statement, native roles return all those raw values. Admins also struggle to see what federated users actually did during a live session. Host logs might show a shared role name instead of the specific partner person. Teams need a way to check every command and rewrite sensitive fields in results.
Check database and API queries on the wire
Identity tools, roles, and network rules decide who opens a session. Setup alone cannot check what each query does or mask sensitive values in a response once a session starts. When workflows touch Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, or internal HTTP APIs, hoop.dev runs beside those services as an open-source proxy, a sidecar for your Postgres or API. It inspects requests coming in and results going back on the wire.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run. On responses, hoop.dev data masking rewrites matched sensitive values in memory. Furthermore, hoop.dev holds SOC 2 Type II, is MIT licensed, and writes every query and decision to an audit trail that generates evidence for HIPAA, GDPR, and PCI DSS. See the source on GitHub.
Frequently asked questions
How is closed federation different from open federation?
Closed federation restricts trust to a short list of known partner domains and specific groups. Open federation allows logins from any external domain or public social identity provider.
What happens when a partner worker leaves their company?
The partner company disables the worker in their home directory. Because the host system checks home tokens at login, the worker loses host reach fast.
Can native federation hide sensitive data inside a database?
No, native federation only verifies user identity and assigns a starting role at login. Protecting emails, phone numbers, or card numbers in query results requires runtime data masking.
