Rooted in the centuries-old method

first introduced by the Roman Catholic Church at the dawn of the Renaissance, Devil’s Advocacy, is one of the most powerful weapons in the red teaming arsenal. The problem is that Devil’s Advocacy is more of a mindset than a methodology. We created Devil’s Troika™ to provide organizations with a formal framework for using Devil’s Advocacy to introduce contrarian thinking into their planning process so that they can be confident they are making the best decision possible.
