Purple teams are a relatively new concept in the field of cyber security. A purple team is a group of security professionals who combine the perspectives of both red teams (which simulate attacks) and blue teams (which defend against attacks) in order to provide a more comprehensive view of an organization's security posture.

The primary goal of purple teams is to bridge the gap between the red and blue teams, and to facilitate better collaboration and communication between the two groups. By bringing together the expertise and perspectives of both red and blue team members, purple teams are able to provide a more holistic view of an organization's security posture, and to identify areas for improvement in the organization's defenses.

One of the key benefits of purple teams is that they can help organizations to detect and address vulnerabilities that might not be apparent to either the red or blue team working in isolation. For example, a purple team might be able to identify areas where the red team's simulated attacks are being detected and blocked by the blue team's defenses, but where the blue team might still be vulnerable to a more sophisticated or persistent attacker.

In addition, purple teams can help to improve the efficiency and effectiveness of both red and blue teams. By providing a forum for collaboration and information sharing, purple teams can help red and blue teams to learn from each other and to avoid duplication of effort. This can lead to more efficient use of resources, and to more effective defenses against real-world attacks.

However, purple teams do present some challenges and potential drawbacks. For example, purple teams require a significant investment of time and resources, as they involve bringing together members of both red and blue teams. In addition, purple teams can sometimes be difficult to implement in organizations that have a traditional red/blue team structure, as they require a shift in mindset and approach to security.

Overall, purple teams offer a valuable new approach to cyber security, providing a more comprehensive view of an organization's security posture and facilitating better collaboration and communication between red and blue teams. By understanding the benefits and challenges of purple teams, organizations can determine whether this approach is a good fit for their security strategy.
