How LangProtect Supports PCI DSS v4.0.1 Across Enterprise AI

Overview

PCI DSS v4.0.1 introduces important security considerations for organizations using AI in payment-related environments. Employee AI tools, customer-facing applications, RAG systems, and autonomous agents can create new paths for cardholder data exposure. This solution brief explains how LangProtect helps organizations detect and control payment-card data across workforce AI, AI applications, and agent workflows. It explores how Guardia, Armor, and Vector support payment-data protection, AI application security, agent access governance, and AI-specific security evidence.
