Cloud RADIUS Server Built for Passwordless Authentication

Certificates are fundamentally more secure than passwords because they cannot be guessed, shared, or stolen in phishing attacks. With our Dynamic PKI, each certificate is uniquely tied to a user and device, and Cloud RADIUS enforces access by validating the certificate in real-time. Unlike passwords, certificates never travel in plaintext and cannot be reused in credential-stuffing or brute-force attacks. Each access decision is based on proof of identity and device trust, not on the hope that a password hasn't been compromised.

Cloud RADIUS integrates with the identity providers and device management systems you already rely on, including Azure AD/Entra ID, Okta, Google Workspace, Intune, Jamf, and more. This integration ensures that authentication decisions are always tied to a verifiable identity and a managed, compliant device. Real-time lookups against your cloud directory guarantee that employees who leave the organization or fall out of compliance lose access immediately, without manual cleanup.

Cloud RADIUS helps organizations meet compliance mandates by enforcing strong, certificate-based authentication and eliminating the use of weak, password-based logins. Because access is tied to verifiable identities and trusted devices, organizations can demonstrate adherence to frameworks like NIST that require robust access control and auditability. With real-time integration into your identity provider and device compliance systems, Cloud RADIUS ensures that only authorized, compliant users maintain access, making it easier to satisfy auditors and reduce regulatory risk.

To help organizations align with modern compliance standards, Cloud RADIUS supports authentication methods designed to prevent credential theft and unauthorized access. Its primary option, EAP-TLS with certificates issued by our Dynamic PKI, eliminates the risks associated with passwords entirely. For regulated industries, Cloud RADIUS also supports Azure AD MFA for step-up authentication, MAC-based authentication for specialized or non-user devices, or SAML-based credential login for employee personal devices.

Unlike traditional, self-managed RADIUS or NPS environments that require round-the-clock internal administration, Cloud RADIUS is delivered as a fully managed service. Our team handles performance monitoring, scaling, and updates so IT doesn't have to. With an uptime up to 99.999%, 24/7 support, and an SLA that ensures continuous service, organizations can offload operational complexity while maintaining complete confidence that their authentication system is always performing at an enterprise-grade level.

Running your own RADIUS server is resource-intensive. It requires maintaining hardware or virtual servers, handling certificates, patching, scaling, troubleshooting, and integrating with cloud identity systems. Cloud RADIUS offloads all of that work, providing a turnkey, managed solution that integrates seamlessly with Azure AD, Okta, Google Workspace, Intune, and Jamf right out of the box. It gives IT teams freedom to focus on higher-value projects while still improving security.

Running NPS or other legacy RADIUS servers often comes with hidden costs: managing servers, syncing Active Directory, handling updates, and troubleshooting misconfigurations. Cloud RADIUS eliminates this overhead with a fully managed service that requires no on‑premises infrastructure. Integrations with Azure AD, Okta, Google Workspace, Intune, and Jamf happen natively, without the need for extra connectors, sync servers, or maintenance. It's modern authentication delivered as a service rather than a set of manual processes.

RADIUS in cloud computing refers to delivering RADIUS authentication services through cloud-hosted infrastructure rather than on-prem servers. A Cloud RADIUS server validates user and device access to networks such as Wi-Fi, VPN, and wired environments using the RADIUS protocol, but without requiring local hardware deployment.

In a cloud-based RADIUS model, authentication decisions can integrate directly with cloud identity providers, device management platforms, and endpoint security tools. This allows access to be evaluated in real time based on user status, device compliance, and certificate validation rather than relying solely on static credentials stored locally.

By moving RADIUS authentication into the cloud, organizations gain global availability, automatic scaling, and simplified infrastructure management while strengthening security controls.

The primary difference between Cloud RADIUS and on-prem RADIUS lies in infrastructure, scalability, and integration capabilities.

An on-prem RADIUS server requires hardware or virtual machines, shared secret management, replication across locations, and ongoing maintenance. Scaling often involves deploying additional servers and manually configuring redundancy.

A Cloud RADIUS server eliminates hardware management and provides globally distributed infrastructure with high availability. It integrates directly with cloud identity providers and security platforms, enabling real-time identity lookups and dynamic policy enforcement. 

LDAP and RADIUS serve different purposes and are not direct replacements for one another.

LDAP is a directory access protocol used to query and manage identity information stored in directory services. It is commonly used for user lookups and centralized identity storage.

RADIUS, on the other hand, is an authentication and authorization protocol specifically designed for network access control. It evaluates authentication requests and enforces access decisions for Wi-Fi, VPN, and wired networks.

In many environments, LDAP and RADIUS work together. A RADIUS server may query an LDAP directory to validate credentials. However, for secure network authentication, particularly in Cloud RADIUS deployments that use certificate-based authentication, RADIUS is the enforcement mechanism that grants or denies network access.
