Walmart's "Trusted Agent" Approach to Purple Teaming
Walmart brings its red and blue security teams together in the same physical location to conduct purple teaming exercises that strengthen collaborative defense efforts. This co-location approach aims to build mutual trust and improve security outcomes through joint offensive and defensive testing.
Why it matters: Security teams at large enterprises can apply this operational model to reduce silos between red and blue functions, accelerate threat discovery, and validate defenses more effectively.
