Updated October 2026 · CSLB #819788, C-7, C-10, C-28

The short answer

HPE Aruba Networking is networking-first: best-in-class Wi-Fi, strong switching and ClearPass access control, with firewalls from another vendor. Fortinet is security-first: FortiGate firewalls with switches, Wi-Fi and SASE managed together in one Security Fabric, usually at a lower total cost. Many organizations mix them, with Aruba Wi-Fi and switching behind FortiGate firewalls.

Either or both

Mixing vendors

Can you mix Aruba and Fortinet?

Yes, and it's common. Aruba Wi-Fi and switching behind FortiGate firewalls gives you strong networking and strong security. The trade-off is two vendors, two management consoles and some integration work to share policy between ClearPass and FortiGate. A single-vendor stack is simpler to run; a mixed stack is stronger in each area.
