Can I Use Azure With A RADIUS Server?

Organizations worldwide are making the transition to cloud-based network solutions. To ease the transition, Microsoft created Entra to aid clients in moving their directories from on-premise Active Directory (AD) to the cloud. However, Entra is limited compared to AD in terms of support for RADIUS-backed WPA2-Enterprise Wi-Fi. AD is an on-premise solution, and Microsoft Entra ID doesn’t offer an integrated and managed RADIUS solution.

If you plan to migrate to the cloud, you could face challenges that require you to retain your AD-domain hardware.. Luckily, there are many different methods you can use to implement a RADIUS-backed Entra system. SecureW2’s RADIUS solution for Entra ID is entirely cloud-based,  verifies Entra ID identity at the moment of authentication, and is straightforward to set up according to our customers.

Entra ID RADIUS Authentication Services

Since Entra ID does not have native RADIUS server functionality, network administrators need to use several methods to secure their on-prem wireless Internet access, including:

Entra ID with Network Policy Extension (NPS)

A standard method configures Microsoft Entra Multifactor Authentication with an NPS extension for RADIUS authentication. However, configuring this service can be time-consuming and requires ongoing maintenance and management. It also only supports RADIUS authentication and MFA. In addition, this method can only work via a password authentication protocol (PAP), which is far less secure than its 802.1x certificate counterpart.

Entra ID With FreeRADIUS

Another solution for adding RADIUS capability to Entra ID is implementing and configuring a virtual FreeRADIUS server. To do this, network administrators need to secure LDAP for a managed domain in Entra ID DS and create a VM to host FreeRADIUS in the same virtual network as AD DS. Unfortunately, this process is also quite time-consuming, and any missed step can lead to an unsecured network.

This method may be a suitable solution if you have the technical skills and resources. However, most organizations don’t have the time to create a suitable FreeRADIUS solution.

Entra RADIUS Server With SecureW2

Using Microsoft Entra as your SAML provider, you can easily set up a WPA2-Enterprise network equipped with Cloud RADIUS using SecureW2.

Our JoinNow Connector fully integrates your Entra system for WPA2-Enterprise, allowing you to safely and effortlessly use certificate-based security for Entra and AD devices.

How Entra ID Integrates with Cloud RADIUS to Provide Secure Network Access

Entra ID ensures that only authorized users can access an organization’s network resources. Organizations that integrate Entra ID with a Cloud RADIUS solution can increase network security and enforce strong authentication standards.

This is how the integration works:

Identity and Authentication Integration:

Entra ID serves as a directory, maintaining user IDs and providing important information for authentication. Cloud RADIUS implements certificate-based authentication by dynamically referencing this directory with each login.

  • When a person or device seeks to connect, Cloud RADIUS confirms their identification by comparing the digital certificate’s validity to real-time information in Entra ID.
  • This real-time look-up guarantees that existing access regulations are enforced, even if modifications (such as revoking rights or altering roles) were made after the certificate was issued.

SecureW2 streamlines this by providing an easy-to-deploy RADIUS solution that removes manual processes, resulting in a quick and secure integration.

Passwordless Security:

One of the key benefits of combining Entra ID with Cloud RADIUS is the transition to passwordless authentication. By employing certificates instead of passwords, the integration significantly reduces problems such as phishing and credential theft.

SecureW2’s platform automates certificate issuance and lifecycle management while ensuring ongoing compliance, allowing organizations to retain strong security with minimum administrative work.

Seamless User Experience:

SecureW2’s Cloud RADIUS solution improves the user experience by making authentication safe and straightforward. Users get a quick, password-free connection, while administrators benefit from simplified implementation and maintenance.

Organizations can maintain a seamless, secure network for employees, contractors, and BYOD users by utilizing SecureW2’s sophisticated capabilities, such as dynamic policy enforcement and certificate automation.

Best Practices for Entra ID RADIUS Integration

Integrating Entra ID with a Cloud RADIUS server can help transform your  network security—these best practices, paired with SecureW2’s expertise, will help you with a seamless deployment:

1. Prioritize EAP-TLS for Certificate-based Authentication

The EAP-TLS protocol is considered the gold standard for secure network authentication. Unlike password-based methods, it uses digital certificates to authenticate users and devices, removing the possibility of credential theft. SecureW2’s Cloud RADIUS is designed to handle EAP-TLS natively, simplifying certificate issuing and integration while providing a secure, smooth user experience.

2. Automate Certification Provisioning and Lifecycle Management

Manually managing certificates is time-consuming and can be prone to errors. SecureW2’s Cloud RADIUS automates this whole process, from issue to renewal, saving time and lowering administrative costs. Administrators may use advanced monitoring tools to track certificate status, ensuring that devices are always compliant and authorized. This mechanism improves security by preventing expired or incorrectly set certificates from interrupting access.

3. Enforce Conditional Access Policies

Dynamic, real-time access control is critical to current network security. Integrating Entra ID with SecureW2’s Cloud RADIUS allows you to impose fine-grained conditional access controls based on user roles, group memberships, and device compliance. This guarantees that only authorized people and devices may connect, and it automatically adapts to user or device status changes.

4. Use MDM for Comprehensive Device Management

A strong Mobile Device Management (MDM) policy guarantees that only compliant devices—corporate-issued or BYOD—can connect to your network. SecureW2 integrates seamlessly with top MDM systems, such as Jamf and Intune, to enforce device-level policies and simplify security for IoT and corporate devices.

5. Thoroughly Test Before Deployment

Testing your RADIUS configuration before full-scale deployment enables a seamless transition and minimizes interruptions, particularly for remote users. Test the setup with a small group to discover any possible problems. The SecureW2 professional support staff is accessible throughout the testing phase, providing specialized help to evaluate setups and ensure error-free deployment. This proactive strategy minimizes downtime and optimizes the onboarding process for a larger-scale implementation.
