In the ever-evolving landscape of cyber security, new strategies and approaches are constantly being developed to combat the ever-present threat of cyber attacks. One such approach is the concept of a purple team in cyber security, combining elements of red and blue team methodologies.

Understanding the concept of a purple team is crucial for organisations looking to enhance their security posture and improve their incident response capabilities.

Understanding the concept of the purple team

Purple team in cyber security with best practices

A purple team can be defined as a collaborative approach bridging the gap between offensive and defensive cyber security practices. It brings together the skills and expertise of the red and blue teams to test and improve an organisation’s security measures.

By combining the strengths of both teams, a purple team can provide a comprehensive assessment of an organisation’s vulnerabilities and ensure that the necessary controls are in place to mitigate potential risks.

The composition of a purple team in cyber security

A purple team comprises members from the red and blue teams, each bringing their unique skill sets and perspectives to the table. Let’s take a closer look at the roles of these team members.

The red team members

The red team members, often referred to as ethical hackers or penetration testers, are responsible for simulating cyber attacks and identifying vulnerabilities in an organisation’s infrastructure, systems, and applications. These highly skilled professionals possess extensive knowledge of various hacking techniques and tools, enabling them to simulate real-world cyber threats and expose potential weaknesses.

The blue team members

The blue team members, also known as incident response analysts or security engineers, are responsible for defending and protecting an organisation’s systems and data. They are tasked with promptly monitoring, detecting, and responding to security incidents.

Blue team members possess in-depth knowledge of security controls, threat intelligence, and incident response procedures, ensuring that an organisation can effectively respond to and recover from cyber attacks.

The Purple Team approach to cyber security

The collaborative nature of the Purple Team

The collaborative nature of the purple team approach is what sets it apart from other methodologies. It encourages open communication and knowledge sharing between the red and blue teams, fostering a culture of collaboration and mutual learning.

These teams can identify vulnerabilities, test security controls, and develop effective mitigation strategies by working together.

The continuous improvement cycle

Regarding the purple team in cyber security, a fundamental aspect of the approach is the continuous improvement cycle. This cycle involves regular assessment of an organisation’s security measures, with feedback from the red team helping the blue team identify areas of weakness and improve their defences.

This iterative process ensures that an organisation’s security controls evolve and adapt to emerging threats.

Benefits of implementing a purple team in cyber security

Benefits of Implementing a purple team in cyber security in an organisation

Implementing a purple team in cyber security can benefit an organisation’s practices and incident response capabilities.

Enhanced security posture

One of the key benefits of a purple team in cyber security is enhancing an organisation’s security posture. Collaboration between the red and blue teams ensures that all vulnerabilities are identified and addressed promptly, reducing the likelihood of successful cyber attacks.

An organisation can strengthen its overall security defences by proactively testing security controls and implementing necessary improvements.

Improved incident response

Another benefit of a purple team approach is improved incident response capabilities. By working together, the red and blue teams can actively simulate and respond to real-world cyber attacks.

This collaborative approach allows organisations to identify gaps in their incident response plans and refine their processes to ensure effective detection, containment, and remediation of security incidents.

Challenges in Purple Team implementation

Implementation challenges with purple team in cyber security

While implementing a purple team approach can undoubtedly bring significant benefits, organisations may face certain challenges during the implementation phase.

Resource allocation and management

Allocating the necessary resources, such as skilled personnel, tools, and infrastructure, can be a challenge when implementing a purple team in cyber security. The red and blue teams require adequate resources to perform their respective roles effectively.

Organisations must ensure that they have the necessary budget and support to build and maintain a successful purple team in cyber security.

Communication and coordination

The success of a purple team heavily relies on effective communication and coordination between the red and blue teams. It is crucial to establish clear channels of communication, define roles and responsibilities, and ensure that both teams are aligned in their goals and objectives.

Lack of communication and coordination can hinder the effectiveness of the purple team and undermine the collaboration between the red and blue teams.


In today’s ever-changing cyber threat landscape, organisations must stay one step ahead of potential attackers. The purple team approach combines the offensive and defensive capabilities of the red and blue teams to assess an organisation’s security measures comprehensively.

By fostering collaboration, continuous learning, and improvement, a purple team can enhance an organisation’s security posture and improve incident response capabilities. Despite the challenges involved, implementing a purple team in cyber security can prove to be a valuable investment in an organisation’s strategy.
