that's the thing though: security teams composed of grizzled talent absolutely benefit from going to conferences. they bring back what they've learned and leverage their new connections to bring more value to the company. so now you've got this industry-wide norm that the security guys are kind of out of pocket and spend a bunch of time at conferences, but they know their shit and protect the infra so it's all good. if it worked at the last X companies $CISO worked for so they're going to be hesitant to drop the hammer on the netsec team networking.
