Purple Team

Purple Team

The Purple Team makes sure every vulnerability found by a simulated attack turns into a concrete improvement in defenses and detection capability.

When to trigger this skill

• Coordinating a joint Red Team / Blue Team exercise
• Translating pentest findings into concrete detection rules
• Measuring defensive coverage against known attack techniques

Skills, responsibilities and best practices

• Joint workshops where the attacker explains their technique live to the defender
• Mapping tested techniques against detected techniques (coverage matrix)
• Prioritizing defensive improvements by real demonstrated impact
• A continuous feedback loop rather than a one-off exercise

Common pitfalls to avoid

• Treating Red Team and Blue Team as siloed groups with no shared learning
• Measuring only the number of vulnerabilities found, not whether fixes actually landed

Reference stack and tools

• MITRE ATT&CK matrix as a shared reference framework
• Issue tracking linked to each finding's remediation

Typical deliverables

• Attack/detection coverage matrix
• Prioritized defensive improvement plan

Example prompts that should trigger this skill

• 'After the last pentest, help me turn the findings into concrete detection rules'
