Blue Team

A blue team is the defensive side of cybersecurity — the people responsible for maintaining and improving an organization's security defenses, detecting threats, and responding to incidents. In a red team/blue team exercise, the blue team defends against the red team's simulated attacks.

In everyday operations, the blue team includes your security analysts, incident responders, and system administrators who monitor networks, analyze alerts, patch vulnerabilities, and maintain security controls. They're the people keeping your systems secure day to day.
