PAN‑OS® is the software that runs all Palo Alto Networks® next-generation firewalls. By leveraging the three key technologies that are built into PAN‑OS natively—App‑ID, Content‑ID, and User‑ID—you can have complete visibility and control of the applications in use across all users in all locations all the time. And, because the application and threat signatures automatically reprogram your firewall with the latest intelligence, you can be assured that all traffic you allow is free of known and unknown threats.
