It continuously verifies access based on identity context, device posture, and risk signals, unifying passwordless authentication, policy enforcement, and automated response through one policy engine. Built for distributed organizations, Portnox manages access for employees, contractors, service accounts, IoT/OT devices, and AI agents - including unmanaged and BYOD endpoints connecting from outside the traditional perimeter. Its cloud-native architecture replaces the on-premises appliances and legacy VPNs that make traditional NAC slow to deploy, extending risk-based access control to managed and unmanaged devices, SaaS, private applications, and non-human identities. The Portnox Cloud platform delivers Network Access Control (NAC), Secure Remote Access (ZTNA), Always-on Authentication (RADIUS), and Infrastructure Administration (TACACS+) giving security and IT teams real-time visibility into every connection and the ability to instantly restrict, quarantine, or revoke non-compliant access. Portnox manages more than one million devices worldwide, secures 40 million authentication sessions daily, blocks over one million unauthorized access attempts daily, and was named Best-in-Class NAC Solution at RSA 2025. Portnox is often adopted as a cloud-native alternative to Cisco ISE and as a replacement for on-premises NPS and RADIUS infrastructure. Key capabilities: Zero Trust Network Access (ZTNA) – Every session is verified and re-evaluated, replacing the implicit trust legacy VPNs grant by default. Coverage for every identity, including AI agents – Governs employees, service accounts, IoT/OT devices, and AI agents under one policy framework. AI-driven risk intelligence – An AI-powered policy engine scores, prioritizes, and enforces risk in real time. Passwordless authentication & cloud RADIUS – Certificate-based authentication with centralized 802.1X - no on-premises RADIUS servers required. Automated remediation – Restricts, quarantines, or revokes access for any non-compliant or high-risk identity (including a rogue AI agent) without manual intervention. Audit-ready visibility – Real-time access logs and policy-based compliance controls support regulatory audit readiness. Integrations: Portnox integrates with the identity providers and network infrastructure organizations already run Azure AD/Entra ID, Okta, Meraki, Fortinet, and more so teams extend continuous, zero-trust access control without replacing their stack.

The biggest struggle has been how it handles private Wi-Fi addressing and MAC addresses, to the point where we needed someone almost full time just to...
