Welcome the Purple Team, who will bring out the best of Blue and Red together and ensure that Red Teams results move into actions on the Blue Team and vice versa.
Purple teams are needed when the Red and Blue teams are not getting along, they simply ensure that issues picked up by the Red Team are resolved by the Blue Team and that both teams are doing the best they can.
When Red, Blue and Purple teams work in harmony, they ensure business stability and security and constantly work towards mitigating a breach or attack. Without these teams in place, a business is simply burying their heads in the sand and hoping for the best. This is like building ones own super car and then driving it at full tilt on a track without checking the brakes; you know you connected them, they should work, but they dont.
