Portnox delivers universal zero trust access control that eliminates enterprise attack surface through passwordless authentication. The company's cloud-native platform unifies Network Access Control (NAC), Zero Trust Network Access (ZTNA), RADIUS, and TACACS+ to secure users, devices, and networks without requiring hardware appliances or VPN infrastructure. Portnox automatically discovers, profiles, and monitors every managed and unmanaged device attempting to connect to enterprise networks, enforcing security policies consistently across wired, wireless, and VPN access.
Founded in 2007, Portnox serves thousands of enterprises globally, securing millions of devices across distributed networks. The platform reduces breach risk by 75% while delivering 287% ROI according to Forrester analysis. By eliminating the need for on-premises infrastructure, Portnox enables rapid deployment and scalability without the operational overhead of legacy access control systems. The company has received multiple industry awards including recognition from Cyber Defense Magazine, InfoSec Awards, and inclusion in the 2025 Inc. 5000 list of fastest-growing private companies.
