Palo Alto Networks PA-540 hardware firewall

Palo Alto Networks PA-500 Series Next-Generation Firewalls (NGFWs) comprise the PA‑501, PA‑505, PA‑510, PA‑520, PA‑540, PA‑545‑POE, PA‑550, PA‑555‑POE, and PA‑560 models. This series brings ML-Powered NGFW capabilities to distributed enterprise branch offices, retail locations, and midsize businesses.

The controlling element of the PA-500 Series NGFWs is PAN-OS®, the same software that runs all Palo Alto
Networks NGFWs. PAN-OS natively classifies all traffic, including applications, threats, and content, and then
ties that traffic to the user regardless of location or device type. The application, content, and user—the elements that run your business—serve as the basis of your security policies, resulting in an improved security
posture and reduced incident response time. PAN-OS embeds machine learning (ML) in the firewall core to
provide inline signatureless attack prevention for filebased attacks while identifying and immediately stopping
never-before-seen phishing attempts.
