Why cloud-native network access control?

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:

  • Gain visibility into every managed and unmanaged endpoint
  • Enforce access control policies for devices and users
  • Streamline authentication with MFA and identity integrations
  • Scale access control across cloud, remote, and hybrid networks

Key Use Cases for NAC Solutions

  • Secure remote and hybrid workforces – Apply access policies to any device, anywhere, before granting network connectivity.
  • Protect IoT and BYOD environments – Extend visibility and control to unmanaged devices, from smart sensors to personal laptops.
  • Simplify regulatory compliance – Enforce security controls that align with HIPAA, PCI-DSS, SOC 2, and other mandates.
  • Scale without complexity – Secure network access for thousands of users and endpoints across distributed environments.

Comparing NAC Vendors

When evaluating NAC solutions, enterprises often look at options such as:

  • Cisco ISE – strong enterprise presence, but complex to manage
  • Aruba ClearPass – feature-rich, but requires ongoing appliance management
  • Extreme Networks – strong campus networking focus, less flexible for hybrid work
  • Forescout Platform – robust device discovery, but high total cost of ownership
  • Fortinet FortiNAC – integrates with Fortinet’s ecosystem, but limited innovation and declining support

Portnox differentiates itself as the only cloud-native NAC, delivering flexible access control without on-premise infrastructure.

NAC Solutions vs. Legacy Tools

If you search for “NAC solutions” online, you’ll see frustration with outdated, hardware-heavy systems like Cisco ISE, Aruba ClearPass, and Forescout. We provide a cloud-native alternative with:
  • Agentless endpoint visibility – discover and assess every device without installing or updating software agents.
  • Seamless identity integrations – native connections with modern providers like Okta, Microsoft Entra ID (Azure AD), Ping, and others.
  • Always-on Zero Trust enforcement – continuously monitor device compliance and enforce policies in real time, not just at login.

NAC Best Practices

Implementing effective network access control solutions requires:

  • Understanding risks and endpoint compliance needs
  • Deploying strong authentication measures, including passwordless
  • Maintaining a dedicated access control team to enforce security policies
  • Choosing a trusted vendor that supports cloud and Zero Trust security models

With Portnox, securing every device across hybrid and cloud networks is simple, scalable, and cost-effective. Request a demo today to see how easy NAC can be.

Case Study

Indiana school district secures 15,000 devices with Portnox Cloud—fast

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

FAQs About NAC Solutions

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.
