Cloud Radius for Entra Id
You set up cloud radius for entra id by linking network gear to cloud directory groups. This setup checks user logins and device certs against your main cloud user list. Many IT teams use this approach to unify office Wi-Fi and VPN logins. They map broad directory groups to network roles so engineers can get to work fast. Still, broad group rules often grant full network reach to every person in that group. Once a user logs in, they can touch many servers and databases without extra checks. Ho

You set up cloud radius for entra id by linking network gear to cloud directory groups. This setup checks user logins and device certs against your main cloud user list. Many IT teams use this approach to unify office Wi-Fi and VPN logins. They map broad directory groups to network roles so engineers can get to work fast. Still, broad group rules often grant full network reach to every person in that group. Once a user logs in, they can touch many servers and databases without extra checks.
How cloud radius for entra id works in practice
Traditional network login services rely on local servers that live inside your office data center. Cloud directories do not speak the legacy network login protocol out of the box. To bridge this gap, teams deploy a cloud radius service between network gear and the directory. When an engineer joins the Wi-Fi or VPN, the router sends a login request. The cloud radius service takes that request and checks the user against Entra ID. It can verify a password or check a device certificate installed on the laptop.
Teams usually tie this check to specific user groups inside their cloud directory. If the user belongs to the right engineering group, the radius service sends an approval message. The router or VPN then lets the laptop join the internal network segment. Admins also use device trust rules to block unmanaged laptops from joining the network. This architecture removes the need to run and patch old login servers in every office. It puts all user and group checks in one central cloud spot.
What network login checks solve and what they miss
Using cloud radius for entra id solves the problem of誰 gets onto your network. It stops strangers from joining your office Wi-Fi or logging into your corporate VPN. When someone leaves the company, you disable their cloud account in one single place. That person loses network login rights right away across all your office sites. It also replaces shared Wi-Fi passwords with personal logins or machine certificates.
Yet network entry checks only control the front door to your internal systems. Once the VPN or Wi-Fi lets an engineer in, the radius job is done. The radius server cannot see what queries an engineer runs on a production database. It cannot stop someone from running a dangerous command on a Linux server. Most teams still share database passwords or static keys once users are on the network. If an engineer runs a wide query, raw emails and card numbers show up in full. Network login tools decide who enters the network, not what commands do in flight.

Why teams separate network entry from database and server control
Modern security teams treat network entry and system control as two separate layers. Let the cloud radius service handle Wi-Fi and VPN entry for your staff laptops. That keeps your basic network perimeter clean and ties it to your main directory. Do not rely on network segments alone to protect sensitive databases or cloud servers.
When engineers need to run SQL queries or server commands, check every action at that level. Tie each query and command back to the exact person in your cloud directory. Add approval steps for risky actions instead of granting permanent admin roles to whole groups. Use data masking to rewrite sensitive fields like phone numbers and national IDs in query results. This approach keeps daily work fast while protecting your most important data from mistakes.
Govern statements and responses across databases and APIs
Good config and scoped roles are needed setup. They do not check single queries in flight or mask sensitive fields in returned rows. Across Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, and internal HTTP endpoints, hoop.dev runs beside each supported service as an open-source proxy, a sidecar for your database or API.
First, hoop.dev guardrails block banned queries before they run. Then hoop.dev data masking rewrites matched sensitive values in responses in memory. The audit trail records every statement and verdict per resource. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.
Frequently asked questions
Does Entra ID support the radius protocol on its own?
No, Entra ID does not handle radius traffic natively without extra tools or services. Teams use either local server extensions or a managed cloud radius service to bridge the gap.
Should we use passwords or certificates for cloud radius logins?
Certificates are much safer because users do not type passwords that attackers can steal. Most teams push machine certificates to company laptops using their device management tool.
Does cloud radius control what users do inside databases after login?
No, radius only checks the user when they first join the Wi-Fi or VPN. It has no view into database queries, server commands, or data returned during a session.
