In some areas, compared to other SD-WANs, Prisma SD-WAN has fewer features. First of all, sometimes, if one device is down, the other device will not come up. When there are two devices and we have created HA, that means one device gets a priority of 100 and the other is given 90. The 100 priority is active and the 90 is the backup. In some cases, the primary device is down, but the secondary device is not becoming active. In that case, we have to reboot the devices, causing an outage. I would also like to see improvement in the product training for customers. Palo Alto has not initiated very much training but they have to do so because this is a new product. If you have experience in a legacy environment, and you are moving to Prisma SD-WAN, you don't have a training framework. That is one of the disadvantages. Although they have a training portal, it is a read-only platform. They need training for engineers so that engineers can work very quickly and properly. And with software upgrades, sometimes the device does not come up and we have to do a manual restart. It doesn't happen every time, maybe one or two times out of 100. It's minimal but it does happen.
