Juniper ATP Cloud is a cloud-based service that provides advanced threat prevention for SRX Series devices. Juniper ATP Cloud can inspect files for malware by sending them to the cloud or performing a hash lookup. To reduce delays in the inspection of files, Juniper ATP Cloud performs the following two functions12:

• Juniper ATP Cloud allows the creation of allowlists. Allowlists are lists of trusted files or domains that are not sent to the cloud for inspection. This reduces the network traffic and the processing time for the files that are known to be safe. You can create allowlists from the Juniper ATP Cloud Web UI or the SRX Series device CLI.
• Juniper ATP Cloud performs a cache lookup on files. Cache lookup is a feature that checks if a file has been previously scanned by Juniper ATP Cloud and returns the cached verdict. This avoids sending the same file to the cloud again and saves bandwidth and time. Cache lookup is enabled by default and can be configured from the SRX Series device CLI. References:

The vSRX is a virtual firewall that offers the same features as the physical SRX Series firewalls, but in a virtualized form factor. It supports next-generation firewall (NGFW) capabilities, networking, and automated lifecycle management. It also integrates with cloud orchestration tools and software-defined networking (SDN) solutions1

The vSRX supports VMXNET3 vNICs, which are optimized for performance in virtualized environments. VMXNET3 vNICs offer enhanced networking features such as jumbo frames, hardware offloads, and multicast filtering2

The vSRX runs on Linux as the base OS, which provides a stable and secure platform for the Junos OS and the firewall functionality. Linux also enables the vSRX to leverage the native hypervisor drivers and APIs for better performance and compatibility3

SRX does not identify the iot device. It streams the metadata to Juniper ATP cloud and Junipe ATP cloud identifies the device.
