Portnox Cloud

Portnox Cloud is an enterprise cloud-native Network Access Control (NAC) and zero-trust endpoint access security platform that delivers automated device authentication, posture assessment, and network segmentation directly from the cloud without requiring on-premises server appliances. Traditional on-premises NAC solutions require cumbersome physical appliances, complex certificate authorities, and ongoing maintenance that strain IT resources. Portnox Cloud eliminates these complexities by delivering 802.1X RADIUS-as-a-service, RadSec, and Certificate-as-a-Service (Cloud PKI) fully hosted in the cloud. The platform integrates seamlessly with cloud identity providers—including Microsoft Entra ID (Azure AD), Google Workspace, and Okta—enabling organizations to enforce certificate-based, passwordless Wi-Fi and wired authentication for corporate endpoints in minutes. Portnox Cloud continuously evaluates endpoint risk posture, verifying operating system patch levels, disk encryption status, and active antivirus software before and after granting access. If an endpoint becomes non-compliant or compromised, Portnox automatically quarantines the device or restricts its network access. With built-in support for IoT device fingerprinting and automated onboarding for BYOD devices, Portnox Cloud delivers comprehensive, accessible zero-trust network access control for distributed modern organizations.
