Federated Access Manager
A federated access manager links your main identity store to outside apps and servers. It lets users log in once and use their group roles across many tools. Teams often set this up to stop making separate local accounts on every system. When teams map broad groups to admin roles, every user gets full read and write power.

A federated access manager links your main identity store to outside apps and servers. It lets users log in once and use their group roles across many tools. Teams often set this up to stop making separate local accounts on every system. When teams map broad groups to admin roles, every user gets full read and write power.
How a federated access manager works in practice
First, you establish trust between your central directory and each target tool or database. The central directory acts as the single source of truth for user identities. You upload a signing certificate from your identity provider to the target system. This certificate lets the target system check that login assertions are real and unaltered.
Next, you map central user groups to local roles inside the target system. When an engineer tries to log in, the target system sends them to the identity provider. The identity provider checks their password and second factor, then builds a signed token. That token holds the user identity and a list of their current group names.
The user browser or client sends this signed token back to the target system. The target system checks the signature and reads the group list inside the token. It matches those group names to local roles and starts an active session. When someone leaves the company, you disable one central account to stop new logins.
Why role mapping leaves gaps inside active sessions
This setup solves account sprawl and stops teams from sharing static passwords on chat apps. It also makes user onboarding and offboarding much faster for IT and security teams. Central logs show who logged into which system and when that login took place. Still, federated login only decides who gets through the front door at the start.
Once the session starts, the identity provider steps out of the way completely. It cannot see or check the individual SQL queries or shell commands run in flight. If an engineer maps to a write role, they can drop tables or delete files. A federated login cannot pause a risky command and ask a manager for approval.

Native group mapping also fails to protect sensitive fields inside query results. When a user runs a read query, the database returns every matching row in full. The login tool cannot rewrite emails, phone numbers, card numbers, or national IDs in results. Teams end up building dozens of narrow roles or copying databases to hide private data.
Managing permissions across database and cloud roles
Many teams try to fix this gap by creating more specific groups in their directory. They build separate read, write, and admin groups for every single database and server. Soon, the central directory holds hundreds of role groups that nobody understands or reviews. Engineers wait days for ticket approvals just to run one fix in production.
Even with narrow groups, standing permissions stay active all day and all night. An engineer who needs write permissions for five minutes keeps that role for months. If an attacker steals an active session token, they get all those standing permissions too. True control requires checking every action and query at the moment it runs.
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 single sign-on and federated identity?
Single sign-on lets a user log in once to open many internal apps. Federated identity extends that trust across separate security domains, cloud accounts, and partner systems.
Does federated login control what queries a user runs?
No, federated login only verifies identity and assigns a starting role at login time. After the session begins, the target database or server handles all command checks on its own.
What happens when a federated user changes teams?
When you move the user to a new group, their next login gets new roles. Still, any active sessions they already opened may keep old permissions until those tokens expire.
