Pen Test Partners' Purple Teaming service combines offensive (Red Team) and defensive (Blue Team) capabilities in a collaborative engagement model. Unlike traditional Red Team exercises, Purple Teaming is conducted in coordination with the client, allowing both attack simulation and defensive evaluation to occur simultaneously. The Red Team develops and applies attack use-cases based on real-world attacker tactics and techniques drawn from the company's Incident Response division. These use-cases are mapped to the MITRE ATT&CK framework and cover the breadth of the kill chain to evaluate Blue Team detection and response capabilities. Attack patterns are applied in escalating levels of sophistication until the Blue Team can no longer detect them, providing a measurable baseline for defensive capability. The service generates tangible metrics, identifies multiple pathways to compromise, and maps progress in reducing attack surface over time. Threat modelling is a core component, with attack scenarios designed to reflect realistic threat actors including nation states, organised criminal gangs, blackhat hackers, journalists, competitors, activists, and insider threats. A typical engagement includes: - Maturity assessment using the Identify, Protect, Detect, Respond, Recover framework - Documentation review and interviews - Network exploration - Attack simulation across the kill chain The service is designed to produce a clear action list, measurable metrics, and a roadmap for improving defensive controls rather than simply demonstrating compromise.
