You set up a managed radius server azure ad link by pairing cloud RADIUS with Microsoft Entra ID. This setup lets staff log in to Wi-Fi and VPNs with their work accounts. Most teams used to run local Windows servers for this task. Those old servers needed constant patching and local hardware care. Moving to a cloud RADIUS service removes that heavy server upkeep. Still, network login checks only guard the front door. Once a user joins the network, broad roles often let them reach every internal database.
How a managed radius server azure ad setup works
A cloud RADIUS service acts as a bridge between network gear and your user list. First, you register a custom app inside your Microsoft Entra ID tenant. Next, you grant that app permission to read user groups and check identity status. You then point your Wi-Fi access points and VPN gear to the RADIUS server IP. You also share a secret text string between the network gear and the RADIUS server.
Most teams pick certificate logins or password checks for their staff devices. With certificates, your device management tool pushes a unique digital file to each laptop. When a worker turns on their laptop, it sends that file to the Wi-Fi gear. The Wi-Fi gear passes the login request to the cloud RADIUS service. The RADIUS service checks if the user is active inside Microsoft Entra ID. If the user is valid, the server tells the Wi-Fi gear to open the network.
Where network login checks fall short for internal data
A cloud RADIUS setup solves the problem of local network hardware and shared Wi-Fi passwords. When someone leaves the company, you turn off their account in one main place. They lose Wi-Fi and VPN network admission right away. You also get a clear log showing when each laptop joined the office network.
Still, network admission is only the very first step in data safety. RADIUS and VPN tools only decide who gets onto the office network. They do not watch or control what an engineer does after logging in. Once on the VPN, a user still needs database passwords or SSH keys. Teams often share wide admin accounts so developers can fix bugs fast. A network log will show that a laptop joined the VPN at nine. It will not show which SQL queries ran or which customer records came back. If an engineer runs a bad delete command, the RADIUS server cannot stop it. To protect production data, teams must check every query and command in flight. They also need a way to mask sensitive fields like emails, phone numbers, and card numbers.

Best practices for cloud network and database rules
Start by moving your Wi-Fi and VPN checks to certificate logins when you can. Certificates stop attackers from stealing passwords over the air. Next, split your network into smaller zones based on user groups in your directory. Do not put production servers on the same flat network as office laptops. Finally, pair your network login setup with strict controls at the database and server level. Check every single command and rewrite sensitive text before results reach the user screen.
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 sits inline in the wire protocol beside those services as an open-source proxy, a sidecar for your Postgres or API. On every query an AI agent or engineer runs against production, hoop.dev decides to pass, mask, block, or hold it for human review.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run, and hoop.dev data masking rewrites matched sensitive values in responses 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
Does Microsoft Entra ID have a built-in RADIUS server?
No, it does not include a native cloud RADIUS endpoint out of the box. You must use a third-party cloud RADIUS service or run local Windows servers with extensions.
Should we use certificates or passwords for cloud RADIUS logins?
Certificates are much safer because users never type a password that thieves can steal. Your device tool pushes the certificate to each work laptop without user effort.
Does a cloud RADIUS server control what users do inside databases?
No, RADIUS only checks if a user or device can join the Wi-Fi or VPN. It cannot read, block, or log the SQL queries or server commands a user runs.
