SNMP-based Discovery for IoT Devices

Prisma SD-WAN supports the discovery of devices that are not directly connected to the Prisma SD-WAN branch ION devices by using SNMP (Simple Network Management Protocol) to discover IoT devices within a branch network. The ION devices inspect packets, extract information, and generate messages to send to Strata Logging Service in a specific format. IoT Security obtains this information from Strata Logging Service and lists all the devices discovered in its portal. It also lists details such as IP address, MAC address, vendor details, and so on, for greater visibility.

The ION devices inspect network traffic and use SNMP and LLDP (Link Layer Discovery Protocol) to intelligently discover and gather details for off-branch devices. The system sends this comprehensive device inventory data to the Strata Logging Service, which IoT Security uses to provide complete visibility within its portal.
