And a special thanks to the authors of the first Red Team Capability Maturity Model for blazing the trail. With their model, they sought to provide a simplified view of maturity to help get teams into the discussion without the overhead that can come with fully standardized models like this one. On our own team, we started by using their model. You can find it here.
