Is Palo Alto's "Wildfire" product actually worth it?

tl;dr - It's hella expensive and seems to just be a lot of "We do magic and buzzwords to keep you safe maybe!"

We're doing a review of all of our cyber-sec costs, and I'm always at a struggle to justify the utterly insane costs of Palo Alto's various licenses (especially for the really big firewalls). We're spending nearly $150k/year per feature, and I look at each of those features and thing "That could be the salary of a dedicated InfoSec employee, or another one of me so I can actually do projects besides only putting out fires".

I wouldn't ditch Threat Prevention, or URL filtering, but Wildfire I am having a harder time justifying.
