You set up an azure radius server by running Windows Server Network Policy Server in Azure. You can also connect it to Microsoft Entra ID for multi-factor checks. Teams often build this setup to centralize VPN and Wi-Fi logins. When network roles are too broad, any logged-in user can reach internal databases and servers.
How an azure radius server works in the cloud
Microsoft does not offer a built-in cloud service for the RADIUS protocol. Instead, teams run virtual machines with Network Policy Server inside a virtual network. You can also pair an on-premises server with a cloud extension for two-step checks. When a user tries to join a VPN, the network device sends a login request. The server checks the user account against the central directory. Next, it triggers a second check on the user's phone if rules require it. Once the user passes the check, the server sends an approval message back. The VPN or Wi-Fi device then lets the user onto the network. Teams often run two servers in separate zones so logins stay up if one fails. You must also lock down the network ports between the VPN and the server. Shared secret keys protect the traffic between the network gear and the RADIUS host. If those keys leak, an attacker could fake login approvals on the network.
What network login servers solve and what they miss
A central RADIUS setup stops unknown users from joining your private network. It replaces local accounts on routers and switches with one directory. You can block a user in one place when they leave the team. It also adds two-step login prompts to older network gear. Still, this setup only checks who can enter the network at the front door. Once a user passes the check, the server steps out of the way. It cannot see what queries an engineer runs on a database. It does not log which commands an admin types inside a production server. Users often keep broad database passwords on their laptops to do their daily work. If a laptop gets stolen, the attacker might abuse an open VPN session. Also, compliance teams need clear logs of every action taken on private data. Network login logs only show when a user joined or left the VPN. They do not protect sensitive fields like emails, phone numbers, or card numbers in results. To fix this gap, teams need controls that work at the command and query level.
Moving from network perimeters to request-level checks
Relying only on network entry checks leaves internal systems open to mistakes. A developer with valid VPN rights might still run a bad query by accident. They could drop a table or pull thousands of customer card numbers. Giving out whole network routes is too broad for daily database and server tasks. Teams get better safety when they check each database query and shell command in flight. Instead of opening the whole network, you can check identity on every single action. This approach lets you approve risky commands before they run on the host. It also lets you rewrite sensitive fields like national IDs in query results right away.

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 Azure have a native managed RADIUS service?
No, Azure does not have a single native managed service for RADIUS today. You must run Network Policy Server on virtual machines or use third-party tools.
How do you add multi-factor prompts to RADIUS logins?
You install the Microsoft Entra ID extension on your Network Policy Server host. This extension triggers a phone prompt after the server checks the user's password.
Why is RADIUS not enough for database security?
RADIUS only approves the initial network or VPN login for a user. It cannot inspect, log, or block the SQL queries a user runs afterward.
