Chris Umbel runs site reliability for Zscaler, a global zero-trust security cloud. His team handles 150,000 alerts and 120 incidents monthly - often pulling 30+ engineers per bridge.

If you're drowning in alerts and war rooms keep growing, this is for you. Chris walks through what worked, what didn't, and the specific changes that freed up real engineering capacity.
