What is Purple Team?

A purple team is red and blue working together in one loop: attackers explain each technique while defenders tune detection in real time. The goal is measurable detection improvement, not a win or loss.

A collaborative security exercise in which red team (offensive) and blue team (defensive) practitioners work together in real time to simulate attacks and immediately measure detection and response quality. Rather than red team operating covertly for weeks, purple teaming creates shared visibility so that each offensive action directly informs defensive rule tuning. This approach accelerates improvements to detection logic, alert thresholds, and incident response playbooks.
