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

NAC Solutions vs. Legacy Tools

If you search for “NAC solutions” online, you’ll see frustration with outdated, hardware-heavy systems. Legacy platforms like Cisco ISE, Aruba ClearPass, and Forescout Platform are powerful but often require dedicated staff and constant maintenance.

By contrast, we provide a cloud-native network access control solution with:

  • Zero hardware footprint: No costly on-site appliances to buy, rack, or maintain.
  • 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.

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

When evaluating NAC solutions, enterprises often find common issues like:

  • complex to manage
  • requires ongoing appliance management
  • less flexible for hybrid work
  • high total cost of ownership

Portnox differentiates itself by being the only cloud-native NAC system, delivering flexible network access control without the burden of on-premise infrastructure.

Common Use Cases

  • 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.

NAC Best Practice

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.
