Federated Connection
You set up a federated connection by linking your identity provider to your backend systems. This link lets engineers log in using their existing work accounts instead of new passwords. Most teams map broad group roles in the identity provider to local database or server roles. When these mapped roles are too wide, one login gives an engineer way too much power.

You set up a federated connection by linking your identity provider to your backend systems. This link lets engineers log in using their existing work accounts instead of new passwords. Most teams map broad group roles in the identity provider to local database or server roles. When these mapped roles are too wide, one login gives an engineer way too much power.
How a federated connection works
A federated connection relies on a trust link between two separate systems. The first system is your identity provider, which holds user accounts and group names. The second system is the target database, cloud account, or internal server. You set up both sides to agree on a shared digital key and format.
When an engineer tries to log in, the target system sends them to the identity provider. The identity provider checks who the person is and asks for a second factor. Once the user passes that check, the provider builds a signed digital claim. This claim holds the user identity, email address, and assigned team groups.
The user sends this signed claim back to the target system to finish logging in. The target system checks the signature using the shared key it saved earlier. Next, the system reads the group names inside the claim and matches them to a local role. The user then enters the session with all the rights tied to that local role.
What native identity federation solves and what it misses
This native trust setup solves the problem of scattered passwords across your company. You do not need to create or delete local accounts on every single server. When someone leaves the team, you turn off their main account in one place. They lose their login path to every linked system right away.
Still, federation only checks who can log in at the start of a session. Once the session starts, the identity provider steps out of the picture completely. It does not see or control what commands or queries the user runs in flight. If an engineer maps to an admin role, they can drop tables or read secret rows.

Teams often grant wide roles because making fine rules for every task takes too much time. An engineer who needs to fix one bug gets full write rights for the whole day. Native login logs only show that the person signed in at a certain time. They do not record the exact actions taken or rewrite sensitive data like emails or card numbers.
Closing the gap inside active sessions
To keep systems safe, you need controls that work after the login check finishes. Instead of trusting a wide role for hours, you should check each command before it runs. This approach lets engineers do their daily work while blocking risky queries in real time.
You can also add step-up checks when someone runs a command that changes production data. A peer can review and approve the single command right from a chat app. For read queries, automated rules can rewrite phone numbers or national IDs in the results. Combining central login with command-level checks gives you full control over your systems.
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
What is the difference between single sign-on and a federated connection?
Single sign-on lets a user log in once to reach many apps inside one domain. Federation goes further by linking identity trust across separate domains and different company systems.
What happens to active sessions when a user account is disabled?
Turning off an account in the identity provider stops new logins right away. Still, open sessions on the target system often stay live until their local timer runs out.
Does federation hide sensitive data inside database query results?
No, identity federation only checks who you are when you first sign in. To rewrite fields like emails or card numbers in results, you need data masking rules.
