What is blue team?

A blue team is a group of cybersecurity professionals responsible for defending an organization’s digital infrastructure against attacks. While the red team simulates attacks, the blue team are the defenders—they monitor, detect, analyze, and respond to threats in real time to prevent damage and ensure operational continuity.

Think of the blue team as the security guards and alarm systems of a building. They’re always on duty, watching for signs of intrusion, and reacting quickly if someone tries to break in. While the red team tests the doors, the blue team ensures they’re locked and under surveillance.
