What is Purple Team and how does it work?

Cyber security is like a chess game: Every move has a counter-move. For each attack vector, we have to develop a defense strategy.

But defense alone is not enough; we need to understand the attackers’ techniques, tactics and procedures. This is why the concept of the “purple team” emerged, which refers to the cooperation of red and blue teams.

Purple team offers a comprehensive approach to information security that integrates both the attacker’s perspective and defense mechanisms. Data from attack simulations drives the development of defense tactics.

Purple Team Tanımı

Purple team is a multi-dimensional security testing methodology in the field of cyber security, where both offensive and defensive teams work together. It takes its name from the color formed by the combination of red and blue teams. The main purpose of this team is to create a more effective environment to combat threats by identifying vulnerabilities and improving defense strategies in real time.

Its functioning is to test networks and systems under realistic threat simulations, during which attack methods and defense mechanisms are continuously developed in coordination. During the Purple team’s work, attack scenarios provided by the red team aim to sharpen the blue team’s defense capabilities. Through this dynamic collaboration, the security posture of organizations is continuously strengthened and they become more resilient against potential security breaches.
