Red Team vs Blue Team vs Purple Team
These exercise teams describe the two sides of a security engagement and the bridge between them. Red attacks, blue defends, and purple makes sure the two actually learn from each other. The exam uses the color to signal the role.
Last updated August 2026
| 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.

FAQ
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.
