Using a 'trusted agent' model, blue team members observe red team offensive exercises in real time, checking telemetry and detections while protecting business operations. The focus is on building trust and psychological safety rather than a win-lose competition, which O'Dell says improves both teams' skills, boosts organizational security posture, and aids staff retention. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is a trusted agent model in purple teaming? It is an approach where blue team members sit with the red team during live adversarial emulation exercises, observing in real time whether telemetry, logs, and detections are functioning while also protecting the business from harm during the exercise. Walmart's security operations use this model, co-locating red and blue teams in the same business unit to build trust and reduce the win-lose competitive dynamic between offensive and defensive testers. _Teams refining collaborative security exercises can track evolving practices like this on daily.dev._ ## Similar posts on daily.dev - [Walmart Leaders Transform SecOps Without Going Bananas](https://daily.dev/posts/walmart-leaders-transform-secops-without-going-bananas-m91q05ghr) · Dark Reading · 0 upvotes · 0 comments - [Using continuous purple teaming to protect fast-paced enterprise environments](https://daily.dev/posts/using-continuous-purple-teaming-to-protect-fast-paced-enterprise-environments-quxvff6xr) · InfoWorld · 0 upvotes · 0 comments - [The hard part of purple teaming starts after detection](https://daily.dev/posts/the-hard-part-of-purple-teaming-starts-after-detection-nkzhk8zij) · CSO Online · 0 upvotes · 0 comments - [Why you should purple team your SOC](https://daily.dev/posts/why-you-should-purple-team-your-soc-ld1rjkaxr) · CSO Online · 0 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security) [View this post on daily.dev](https://daily.dev/posts/walmart-transforms-security-teams-with-purple-teaming-onxcczixq) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Walmart Transforms Security Teams With Purple Teaming","url":"https://daily.dev/posts/walmart-transforms-security-teams-with-purple-teaming-onxcczixq","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/walmart-transforms-security-teams-with-purple-teaming-onxcczixq"},"datePublished":"2026-08-12T18:06:44.506Z","dateModified":"2026-08-12T18:07:07.490Z","description":"Walmart's Global VP of Security Operations, Jason O'Dell, describes a collaborative approach to purple teaming that co-locates red and blue security teams in...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/8895036f502e03158cc61d3620210e77?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/8895036f502e03158cc61d3620210e77?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Dark Reading","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Dark Reading","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/dr","url":"https://daily.dev/sources/dr"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/walmart-transforms-security-teams-with-purple-teaming-onxcczixq","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"security","timeRequired":"PT4M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Dark Reading","item":"https://daily.dev/sources/dr"},{"@type":"ListItem","position":3,"name":"Walmart Transforms Security Teams With Purple Teaming"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/walmart-transforms-security-teams-with-purple-teaming-onxcczixq#faq","mainEntity":[{"@type":"Question","name":"What is a trusted agent model in purple teaming?","acceptedAnswer":{"@type":"Answer","text":"It is an approach where blue team members sit with the red team during live adversarial emulation exercises, observing in real time whether telemetry, logs, and detections are functioning while also protecting the business from harm during the exercise.
