Overview

Passwordless Wi-Fi on Meraki, Powered by EAP-TLS and Cloud RADIUS

SecureW2 replaces outdated network systems with a managed, cloud-based Dynamic PKI that automates enrollment, validation, and device revocation using real-time security data. It performs automated identity and posture checks during device enrollment via the JoinNow app, verifying user status with corporate directories before issuing hardware-bound certificates. Radiator servers serve as high-performance authentication engines, routing checks directly to the cloud CA chain. The system evaluates live identity data and manages token lifecycles automatically, reducing deployment time to a few hours.

How It Works

Two Core Architectural Enforcement Paths

Automated Onboarding and Cryptographic EAP-TLS Authentication

Endpoints provision non-exportable client certificates via the JoinNow application suite. When an endpoint establishes a network connection, the Radiator server initiates a native EAP-TLS protocol challenge, validating the client token directly against the SecureW2 cloud CA chain to permit access without password entry blocks.

Real-Time Telemetry and Dynamic RADIUS Attribution

The SecureW2 platform queries linked device management registries and identity provider records in real time. If an endpoint encounters a security hazard or triggers a compliance alert, the policy engine revokes the certificate authority token instantly, preventing subsequent authentication accept loops inside the Radiator core.

Use Cases

Deployment & Architecture Detail

PSK and PEAP Replacement

Shared-password Wi-Fi  , whether a single PSK broadcast across the organization or PEAP-MSCHAPv2 with user passwords, carries inherent risk. A compromised PSK grants access to any device. PEAP credentials can be phished through rogue access points. Certificates eliminate both attack surfaces.

 

With EAP-TLS, each device holds a unique certificate bound to its hardware credential store. There is no shared secret to steal and no password to phish. An attacker who captures network traffic gains no credential that can be replayed on another device. Cloud RADIUS validates the certificate's chain of trust, expiry, and revocation status at every connection attempt, then performs a live identity provider lookup to confirm the user is still active and authorized.

Webhook-Based Certificate Lifecycle Automation​

SecureW2 manages the entire certificate lifecycle—issuance, renewal, and revocation—automatically without manual intervention on the Radiator AP. Certificates are issued with a configurable validity period and renewed automatically before expiry. On MDM-managed devices, renewal is pushed silently as a new profile, while on JoinNow-enrolled devices, the network profile triggers silent renewal, replacing the expiring certificate without user prompts. Suspension is immediate; if a device is flagged as non-compliant, lost, stolen, or unenrolled, SecureW2 disconnects the device in real time.

 

Cloud RADIUS checks the revocation list at each EAP-TLS authentication, denying access if revoked, with no action needed from the Radiator AP. This model removes the need for manual certificate management. Administrators set revocation policies based on IdP group membership, MDM compliance, or manual actions, with enforcement automatic across all Radiator APs.

Frequently Asked Questions

Radiator Integration — Common Questions

How long does it take to set up SecureW2 with Radiator networks?

Setup time is measured in hours because SecureW2 eliminates the heavy lifting normally associated with building PKI and RADIUS infrastructure. By connecting Radiator directly to our Dynamic PKI, organizations can quickly enforce EAP-TLS for Wi-Fi and certificate-backed access for VPN. Once identity provider and MDM integrations are established, policy-based Zero Trust controls are applied as certificates are issued.

Which Radiator products are supported with SecureW2?

SecureW2 fully supports Radiator for Wi-Fi authentication and roaming. By integrating directly with Radiator's 802.1X infrastructure, SecureW2 provides certificate-based authentication for Wi-Fi, dynamic VLAN segmentation, and secure remote access. Whether the environment is a small branch deployment or a global distributed network, SecureW2’s cloud-native PKI scales seamlessly without requiring additional hardware.

How are certificates deployed to devices in a Radiator environment?

Certificates are deployed through different methods depending on device ownership. For managed endpoints, SecureW2 integrates with MDM platforms such as Intune, Jamf, or Workspace ONE to silently issue and install certificates without user intervention. For unmanaged or BYOD devices, users are guided through SecureW2’s JoinNow onboarding client to complete a self-service enrollment workflow. In both cases, certificates are automatically delivered with the correct SSID or VPN settings so that devices can immediately connect using EAP‑TLS authentication.

How does certificate renewal and revocation work for Radiator Wi-Fi and VPN?

In a Radiator deployment, SecureW2 continuously enforces Zero Trust by tying certificate renewal and revocation to user identity and device posture. Certificates are silently renewed in the background, ensuring uninterrupted access for trusted endpoints. If a device is compromised, unenrolled, or no longer compliant with MDM policies, SecureW2 can instantly revoke its certificate, blocking Wi‑Fi and VPN connectivity. This prevents unauthorized access in real time without relying on weak credentials or manual IT intervention.

What authentication protocols are supported in Radiator deployments with SecureW2?

All of the key protocols a Radiator deployment requires are supported by SecureW2 out of the box. That includes EAP‑TLS (for Wi‑Fi and wired 802.1X), SAML 2.0 (for VPN), and onboarding standards like Dynamic SCEP and ACME. SecureW2 also integrates easily with OAuth 2.0 and OpenID Connect identity flows, ensuring customers can connect their existing IdPs and MDMs. This makes deploying certificate‑based authentication with Radiator networks both secure and straightforward.

Does SecureW2 support multi-tenant or multi-SSID Radiator environments (e.g., guest vs. corporate)?

Yes. SecureW2 supports both multi‑SSID and multi‑tenant Radiator deployments, a common requirement for universities and distributed enterprises. IT teams can map different SSIDs to different onboarding portals, certificate policies, and VLAN assignments, ensuring each user group or tenant has the right level of network access. This provides a scalable way to deliver secure Wi‑Fi and VPN access across large or complex Radiator environments.
