HPE Aruba Networking ClearPass vs Fortinet FortiNAC: Network Access Control Compared

HPE Aruba Networking ClearPass and Fortinet FortiNAC are both mature network access control platforms that authenticate users and devices, profile what connects, and enforce role-based segmentation across multivendor wired, wireless, and VPN networks. The decision usually turns on two questions: how deep your policy and AAA requirements run, and how much you have invested in the Fortinet Security Fabric. ClearPass is the more granular, vendor-agnostic policy engine with full TACACS+ device administration. FortiNAC is the stronger choice when you want NAC tightly wired into FortiGate, FortiSwitch, FortiAP, and automated threat response across the Fabric. This guide compares both across policy depth, agentless profiling and IoT discovery, guest and BYOD, segmentation, licensing, and federal procurement so the right buyer can choose with confidence.

The short answer

Pick HPE Aruba Networking ClearPass when you need a deep, flexible policy engine, full RADIUS and TACACS+ AAA for device administration, rich guest and BYOD onboarding, and vendor-agnostic enforcement that does not assume one firewall brand. ClearPass also fits naturally into HPE Aruba and Juniper estates after the HPE networking consolidation. Pick Fortinet FortiNAC when your security stack is already built on the Fortinet Security Fabric and you want NAC, FortiGate firewalls, and automated threat containment to act as one coordinated system, with broad switch and AP interoperability and strong agentless IoT discovery. For heterogeneous enterprises that want the strongest standalone policy and AAA platform, ClearPass leads. For Fortinet-standardized shops chasing single-vendor consolidation, FortiNAC is the more economical and operationally tight fit.

Security Fabric / Ecosystem Integration

Integrates with Aruba Central and the HPE Aruba 360 Secure Fabric; not tied to one firewall vendor.

Deep native integration with FortiGate, FortiSwitch, FortiAP, and automated response across the Fortinet Security Fabric.advantage

Segmentation & Threat Response

Dynamic role-based segmentation with downloadable roles, VLANs, and ACLs; posture via OnGuard.

Micro-segmentation plus automated quarantine and response coordinated with FortiGate and FortiAnalyzer.advantage

Posture / Endpoint Health

ClearPass OnGuard delivers persistent and dissolvable posture checks over wired, wireless, and VPN.advantage

Offers endpoint compliance checks, typically lighter than ClearPass OnGuard for detailed health policy.

Deployment & Operations

Hardware or virtual appliances with publisher and subscriber clustering; flexible but requires policy design effort.

Hardware or virtual appliances; simpler to stand up when the rest of the stack is already Fortinet.

Licensing & Value

Modular Platform plus Access, Onboard, and OnGuard licensing; buy only the capabilities you need.

Per-device concurrent licensing; best value when bundled into a broader Fortinet Security Fabric purchase.

Federal & TAA

Available on federal vehicles; we can source TAA-compliant ClearPass configurations.advantage

Available to government buyers; procurement strongest when paired with a wider Fortinet deployment.

Frequently asked

What is the main difference between HPE Aruba Networking ClearPass and Fortinet FortiNAC?

Both are NAC platforms that authenticate, profile, and segment devices across multivendor networks. The core difference is depth versus ecosystem fit. ClearPass is the more granular standalone policy engine with full RADIUS and TACACS+ AAA, while FortiNAC delivers its strongest value tightly integrated into the Fortinet Security Fabric with FortiGate and automated response.

Is ClearPass or FortiNAC better for IoT and agentless device discovery?

Both are strong. FortiNAC is fully agentless and identifies a very large catalog of device types using many data sources and FortiGuard IoT Services. ClearPass profiles agentlessly too and adds Device Insight, a cloud machine learning service with deep packet inspection. For pure agentless breadth they are close; ClearPass tends to lead on detailed policy once devices are identified.

Does FortiNAC work with non-Fortinet switches and access points?

Yes. FortiNAC interoperates with and configures network devices from a very wide list of vendors, well beyond Fortinet hardware, so it is not limited to all-Fortinet networks. Its deepest automation and threat response, however, come from integration with the Fortinet Security Fabric.

Which platform has stronger guest access and BYOD onboarding?

ClearPass generally leads here. It includes built-in guest portals and the Onboard module for certificate-based provisioning across Windows, macOS, iOS, Android, ChromeOS, and Ubuntu. FortiNAC provides guest and BYOD registration, but its portal and certificate workflows are less extensive than ClearPass Onboard.

Do both ClearPass and FortiNAC support 802.1X and zero trust?

Yes. Both enforce standards-based 802.1X with MAC authentication for headless devices and support role-based, least-privilege access for zero-trust designs. ClearPass adds TACACS+ for device administration, while FortiNAC ties enforcement and automated response into the Security Fabric.

How does licensing compare between ClearPass and FortiNAC?

ClearPass uses modular licensing, a Platform license plus Access, Onboard, and OnGuard, so you buy only the capabilities you need. FortiNAC uses per-device concurrent licensing that is often most economical when bundled into a broader Fortinet Security Fabric purchase.
