Hi Folks, I am trying to secure the NTP on a customer Palo device (pa-220 currently running 9.0.12 and is being upgraded to 10.x.x in a week or so). It current has options for auto-key and symmetrical key for authentication. But from further reading auto-key is not secure (testing it to some public NTP servers like time@cloudflare show no sync) and I haven't found a public NTP server that will run symmetric keys. As I understand it both are being replaced with NTS. Is NTS available on Palo devices, or is my only option using symmetrical keys on a private NTP server? Many Thanks
