Do you need to?", "summary": "Google Cloud's Sensitive Data Protection and Model Armor can help enterprises balance protecting sensitive data with maintaining LLM functionality, according to a blog post by Leo Y. The post argues that aggressively blocking all sensitive data harms internal reasoning, user experience, and downstream autonomous systems, and advises selective de-identification.", "body_md": "When building Generative AI applications for the enterprise, you are likely hyper-aware of the risks surrounding sensitive data. The knee-jerk reaction for many engineering teams is to aggressively block all sensitive data ‒ ranging from PII to financial records and internal credentials ‒ from absolutely everywhere in the stack.\n\nBut a blind, one-size-fits-all approach introduces its own massive headaches. It compromises internal reasoning, ruins user experiences and breaks downstream autonomous systems. As I promised in the first “[How to wear Model Armor](https://leoy.blog/posts/how-to-wear-model-armor-1/)” post, we are going to dive into exactly when to keep sensitive data out of your language models, the reasons you must often avoid de-identifying an agent’s output, and how to orchestrate this balance using Google Cloud’s Sensitive Data Protection (SDP) and Model Armor.", "url": "https://wpnews.pro/news/how-to-wear-model-armor-3-how-you-protect-sensitive-data-from-llm-do-you-need-to", "canonical_source": "https://leoy.blog/posts/how-to-wear-model-armor-3/", "published_at": "2026-08-26 22:03:09+00:00", "updated_at": "2026-08-27 17:50:19.164840+00:00", "lang": "en", "topics": ["ai-safety", "ai-policy", "ai-infrastructure"], "entities": ["Google Cloud", "Model Armor", "Sensitive Data Protection", "Leo Y."], "alternates": {"html": "https://wpnews.pro/news/how-to-wear-model-armor-3-how-you-protect-sensitive-data-from-llm-do-you-need-to", "markdown": "https://wpnews.pro/news/how-to-wear-model-armor-3-how-you-protect-sensitive-data-from-llm-do-you-need-to.md", "text": "https://wpnews.pro/news/how-to-wear-model-armor-3-how-you-protect-sensitive-data-from-llm-do-you-need-to.txt", "jsonld": "https://wpnews.pro/news/how-to-wear-model-armor-3-how-you-protect-sensitive-data-from-llm-do-you-need-to.jsonld"}}
