Walmart's "Trusted Agent" Approach to Purple Teaming

Walmart implemented a 'Trusted Agent' approach to purple teaming by co-locating red and blue teams, fostering trust and improving security through collaborative exercises. This approach enhances communication and mutual understanding between teams, leading to more effective security measures. As a result, Walmart's security posture is strengthened. Engineers can apply this approach by promoting cross-functional collaboration and open communication within their own teams.
