EZRADIUS

EZRADIUS by Keytos is a cloud RADIUS service that helps IT and security teams authenticate users and devices on Wi-Fi, VPN, and wired networks without running on-premises RADIUS infrastructure. Built by ex-Microsoft engineers, it is designed to replace Microsoft NPS, FreeRADIUS, and other legacy RADIUS servers with a fully managed, cloud-native service that integrates natively with Microsoft Entra ID and Intune. Organizations use EZRADIUS to move from password-based network authentication to certificate-based, passwordless access, supporting Zero Trust initiatives, PCI DSS and HIPAA compliance programs, and the retirement of legacy on-premises authentication servers. EZRADIUS supports passwordless, certificate-based authentication via EAP-TLS, along with MSCHAP-v2, EAP-TTLS, PEAP, and MAC Authentication Bypass (MAB). It integrates natively with Microsoft Entra ID and Intune, allowing device compliance and group-membership checks to be enforced at authentication time. Both Classic RADIUS and RadSec (RADIUS over TLS) are supported, with dynamic IP options for distributed and remote sites. EZRADIUS works with any existing PKI or pairs with EZCA, Keytos's cloud certificate authority, for end-to-end passwordless deployment. Audit logs, dashboards, and log streaming to existing SIEM or Azure Log Analytics workspaces are included, and the service is available through the Azure Marketplace with MACC-eligible billing or directly through Keytos with a free trial. Common use cases include WPA2-Enterprise and WPA3-Enterprise Wi-Fi authentication for corporate and guest networks, BYOD certificate enrollment and Wi-Fi profile distribution for non-managed devices, segmented network access for IoT and point-of-sale (POS) devices, VPN authentication, Zero Trust Network Access (ZTNA) rollouts, and migration from Microsoft NPS, FreeRADIUS, and other legacy on-premises RADIUS deployments. EZRADIUS is typically deployed in hours rather than the weeks or months required for on-premises RADIUS, with video tutorials and guides for all the most popular network vendors, including Cisco Meraki, UniFi, Ruckus, and Fortinet. Customers pay only for the identities that authenticate each month and can scale from 10 to 10,000+ identities without changing their configuration.
