What is the difference between red, blue, and purple teams?

The red team plays the attacker and tries to breach systems. The blue team defends, detecting and responding to those attacks. The purple team is the collaboration between them, making sure the defenders learn from exactly how the attackers got in.

Is purple team a separate team?

Often not. Purple team usually describes a function or exercise where red and blue work together and share findings in real time, rather than a permanent standalone team. Its goal is to maximize the value both sides get.

Red Team vs Blue Team vs Purple Team side by side
Aspect	Red team	Blue team	Purple team
Role	Offense: simulate real attackers	Defense: detect and respond	Collaboration: connect offense and defense
Goal	Find and exploit weaknesses	Stop, detect, and contain attacks	Maximize learning from each exercise
Mindset	Think like an adversary	Monitor, harden, and respond	Share findings in real time
Typical activities	Penetration testing, social engineering, exploitation	SOC monitoring, log analysis, incident response, hardening	Joint debriefs, feedback loop, tuning detections
Output	A report of what they got into	Stronger detections and response	Concrete improvements both sides adopt

The bottom line

Red is the attacker, blue is the defender, and purple is less a standing team than the working relationship that makes red and blue improve each other. A good purple-team exercise has the red team show exactly how it got in while the blue team tunes detections to catch it next time. Also know the white team: the referees who run the exercise.
