my TB MBP (Mojave) has been panicking quite often lately upon waking from sleep, and here's the latest panic report:

Does anyone have any idea why this could be happening? I've tried consulting Google, but nothing seems to stand out.

Generally, the first thing to try when diagnosing kernel panics is to remove 3rd party kexts & their associated apps/structures...

net.pulsesecure.PulseSecureFirewall 9.0.2f5
com.symantec.ips.kext   14.2.1f52
com.symantec.nfm.kext   14.2.1f52
com.symantec.internetSecurity.kext  14.2.1f52
at.obdev.nke.LittleSnitch   5208
com.symantec.SymXIPS    8.2.2

I don't specifically know all those except for Little Snitch, which is normally a well-behaved app; but you do seem to have 3 different sets of firewalling & security running alongside each other, which is generally not recommended - they tend to fight.
