Aaron Rinehart expands the possibilities of chaos engineering's applications to other safety-critical portions of the IT domain; notably, cybersecurity. He began pioneering the application of security in chaos engineering during his tenure as the chief security architect at the largest private health care company in the world, UnitedHealth Group (UHG). While at UHG, Rinehart released ChaoSlingr, one of the first open source software releases focused on using chaos engineering in cybersecurity to build more resilient systems. Rinehart recently founded a chaos engineering startup called Verica with Casey Rosenthal from Netflix and is a frequent author, consultant and speaker in the space.
