Portnox is a Network Access Control (NAC) software vendor. NAC sits within the larger field of cybersecurity, and more specifically network security. It is a technology that enables organizations to enact its own unique policy for how and when endpoints (desktops, laptops, smartphones, etc.) can connect to their corporate networks. NAC is designed to allow IT security teams to gain visibility of each device trying to access its network, and specifically the type of device and access layer being used (i.e. wifi, wired ports, or VPN).

As more organizations adopt cloud-based services and remote work options, the need for NAC solutions has become increasingly important. With NAC in place, businesses can better control access to sensitive data, protect against cyber threats, and ensure compliance with industry regulations. NAC solutions also offer a number of benefits, including: Enhanced network security: NAC solutions help ensure that only authorized devices and users have access to the network, reducing the risk of cyber attacks and data breaches. Improved compliance: NAC solutions can help organizations meet regulatory requirements and industry standards by ensuring that all devices accessing the network meet specific security criteria. Increased visibility: NAC solutions provide organizations with greater visibility into their network, enabling them to monitor and manage devices, applications, and network traffic more effectively.
