The case studies presented illustrate the implementation of purple teaming across various organizations, each facing unique cybersecurity challenges and achieving tailored solutions with quantifiable results. In the **automotive company** case, the organization was at an evolving stage of cybersecurity maturity. An automated PowerShell-based framework was employed for their purple team engagement, aligned with the MITRE ATT&CK framework. Over five days, hundreds of test cases were executed, allowing for broad coverage and real-time feedback. This approach enabled the client to identify and close security gaps quickly, adapting the tests based on their immediate concerns. However, as the organization matured and implemented initial recommendations, the same framework faced limitations, necessitating adaptations to validate new security measures. This iterative process ultimately strengthened their defenses. The **manufacturing company** sought to evaluate the effectiveness of its endpoint detection and response (EDR) system against advanced malware. A staged testing approach was developed, progressing from basic payloads to fully customized malware. This method revealed significant gaps in both the EDR's configuration and its inherent capabilities. The client was able to make specific, actionable improvements to their EDR configuration and implement additional defensive tools, enhancing their overall security posture. For the **heavy rail organization**, a comparative assessment was conducted across four subsidiaries, each with its own security operations center (SOC). Instead of identical tests, a standardized level of effort was applied to evaluate each SOC fairly. This tailored approach allowed the parent organization to identify strengths and weaknesses across subsidiaries, guiding resource allocation for improvements. The complexity of varying environments required careful coordination, but the results provided clear insights into where to focus efforts for enhanced security. Lastly, the **SOC-as-a-Service company** represented a highly mature organization where security was deeply integrated into operations. The engagement was hands-on, with specific objectives set for the red team to achieve. Daily debriefs facilitated real-time adjustments to the strategy, allowing for a thorough exploration of defenses. This collaboration led to the identification of critical vulnerabilities that traditional red team engagements might have missed, demonstrating the effectiveness of a persistent adversary simulation. The engagement's success hinged on the high level of involvement from the client's security team, which, while demanding, yielded significant insights and improvements. These case studies collectively highlight the importance of tailored approaches in purple teaming, demonstrating how organizations can effectively address their unique cybersecurity challenges and achieve measurable improvements in their security posture.
