❓ 12. Frequently Asked Questions (FAQ)

Q1: How long does it take to set up a Prisma ION device from scratch? A basic Prisma ION setup — including physical installation, ZTP, site configuration, and basic WAN/LAN configuration — typically takes 2 to 4 hours for an experienced engineer. Full production deployment with policies, QoS, and security integration can take 1 to 3 days depending on complexity. Q2: Can Prisma ION work without internet connectivity to the cloud controller? Yes. Once configured, the Prisma ION device operates with local autonomous routing even if the cloud controller is temporarily unreachable. All routing tables and policies are cached locally. However, policy changes cannot be pushed until controller connectivity is restored. Q3: What is the difference between Prisma SD-WAN and CloudGenix? They are the same product. Palo Alto Networks acquired CloudGenix in 2020 and rebranded it as Prisma SD-WAN. All CloudGenix features have been retained and enhanced, with added integration into the Palo Alto Networks Prisma SASE platform. Q4: Does Prisma ION support MPLS and broadband simultaneously? Absolutely. The ION device can simultaneously use MPLS, broadband internet, LTE/5G, and VSAT links, applying intelligent per-application path selection across all of them. You can route business-critical applications over MPLS while sending streaming and guest traffic over cheaper broadband. Q5: Is Fortinet SD-WAN better than Prisma SD-WAN? Neither is universally "better." Prisma SD-WAN wins for cloud-first enterprises needing superior application intelligence and SASE integration. Fortinet SD-WAN wins for organizations needing cost-effective, integrated NGFW + SD-WAN with flexible on-premises or cloud management. Both are Gartner Magic Quadrant leaders. Q6: What ports need to be open for Prisma ION to communicate with the cloud controller? The Prisma ION device requires the following outbound connectivity: TCP 443 (HTTPS) — Cloud controller management and ZTP UDP 4500 — SD-WAN fabric tunnels (IPSec NAT-T) UDP 500 — IKE for tunnel establishment UDP 123 — NTP time synchronization UDP/TCP 53 — DNS resolution Q7: How do I update the firmware on a Prisma ION device? Firmware updates are managed from the Prisma SD-WAN portal. Navigate to Network > Software > Element OS Images, upload or select the desired firmware version, and push it to devices. The ION device downloads the image, validates the checksum, and installs it — with automatic rollback if installation fails. Always test firmware in a lab or non-production site first. Q8: Can I use Prisma ION with Palo Alto NGFW at the same site? Yes — this is a recommended architecture for high-security sites. The Prisma ION device handles SD-WAN routing and path selection, while a Palo Alto NGFW (PA-Series) or Prisma Access handles deep security inspection. Traffic can be service-chained from ION through the NGFW before reaching users — giving you best-of-breed SD-WAN and security in a complementary architecture.
