Portnox offers a cloud-native NAC solution purpose-built to align with zero trust principles. Unlike traditional NAC systems that rely on hardware appliances and constant upkeep, the Portnox Cloud provides a simple, scalable, and cost-effective way to enforce access control across distributed networks.
Deploying legacy NAC used to be a headache. Complex appliances, expensive licenses, and long deployment cycles made it difficult to achieve the right level of network access control.
With Portnox, organizations can:
See how New Albany Floyd County Consolidated School District rapidly implemented access control with Portnox Cloud to secure a diverse environment of 15,000 endpoints. With limited IT staff and 20 buildings to support, the district deployed in weeks instead of months—gaining real-time device visibility, seamless Chromebook support, and strong security without adding hardware or complexity.
NETWORK ACCESS CONTROL
Network Access Control (NAC) is a cybersecurity solution that authenticates and authorizes users and devices before granting network access. NAC ensures only compliant endpoints connect, helping organizations enforce security policies, improve visibility, and protect sensitive resources from unauthorized access.
NAC solutions support zero trust security by continuously verifying every user and device before allowing network access. They enforce strict authentication and compliance checks, ensuring only authorized, secure, and policy-compliant endpoints can connect to business systems, applications, and critical data.
NAC solutions secure IoT and unmanaged devices by providing agentless visibility and policy enforcement. These tools ensure all devices, regardless of type or ownership, meet security requirements before accessing the network, reducing risks from shadow IT, rogue endpoints, and vulnerable smart devices.
The difference between NAC and ZTNA lies in scope: NAC manages device-level access to networks, while ZTNA secures application-level access for users. Combined, they create a layered zero trust security model that protects both networks and business applications from unauthorized activity.
Cloud-native NAC reduces IT overhead by eliminating on-site appliances, manual updates, and complex maintenance. Unlike legacy systems such as Cisco ISE or Aruba ClearPass, Portnox Cloud automates continuous access control, lowers total cost of ownership, and scales effortlessly across distributed, hybrid environments.
Portnox Cloud extends network access control beyond the traditional on-prem perimeter to secure remote and hybrid users. By enforcing consistent policies regardless of location, Portnox evaluates device posture and user identity before granting access to resources. This ensures only trusted endpoints connect whether users are on-site, remote, or roaming, eliminating security gaps introduced by VPN-only approaches.
Yes. Portnox Cloud’s cloud-native NAC scales across distributed environments—up to enterprise and global footprints—without requiring additional on-prem appliances or complex configurations at each site. Policies are centrally defined and consistently enforced everywhere, reducing operational overhead while maintaining strong access control across campuses, branches, and hybrid networks.
Portnox Cloud unifies network, application, and infrastructure access control in a single cloud-native platform.
With continuous risk evaluation and centralized policy enforcement, organizations gain stronger security without managing disconnected tools.
Cloud-delivered administrative access control providing centralized authentication, authorization, and command auditing for all network infrastructure.
Cloud-native, posture-aware access delivering secure, passwordless connectivity to SaaS and private apps without VPN complexity.
