What can you do to protect your cybersecurity team (CISO included) from burnout?

I think there are three key components to preventing burnout.

First, hire folks who understand the nature of security work.   It involves a lot of hard and often thankless work:  if you're not signed up for that mentally and emotionally, I think you're in the wrong profession.   You do it because it's important, not because it's an adrenaline rush or a chance to shine or even just technically interesting.  

Second, have a strategy that focuses on the organization's critical risks.  If you're responding to every headline and chasing every tool, you'll exhaust yourself and your team without materially reducing the risk to the organization and perhaps without getting very much done at all.   Borrow a page from Agile methods and implement your strategy in focused, sustainable sprints.

Finally, stay fresh and keep your team fresh.   You're either getting smarter every day, or you're getting dumber, so choose smarter.   This should include formal education or certification objectives each year, and it should go well beyond the technical:  you're securing a company, so you need to understand how that company works, and so does your team.   We have a "community policing" block in our regular team meetings where a guest speaker will come in and speak about how clinical, marketing, etc. work-- their key priorities, their fundamental processes and roles, etc.
