Palo Alto Networks Cortex Agentic Endpoint Security (AES) is an endpoint protection and AI security governance platform designed to secure autonomous agents, developer tools, and software components across enterprise devices. The software provides continuous discovery of AI applications, local language models, MCP servers, browser extensions, IDE plugins, and open-source packages that may introduce security risks. Its AI-native visibility capabilities help security teams identify unauthorized software and previously unmanaged AI tools operating within their environments. Context-aware risk analysis evaluates application behavior, permissions, software supply chain relationships, and access to sensitive resources. The platform maintains an AI Context Graph that connects discovered assets with relevant security information to support risk assessment and investigation. Governance tools allow administrators to establish security policies, restrict unsafe interactions, and remove insecure packages or extensions. Runtime protection monitors autonomous agent activity and blocks prohibited actions, malicious downloads, prompt injection attempts, and potential data exfiltration. Cortex AES integrates with Cortex XDR and Prisma AIRS to combine endpoint monitoring with AI application security and threat prevention capabilities. Organizations can deploy the solution as a standalone security product or alongside existing endpoint security infrastructure, with optional managed protection and investigation services from Palo Alto Networks Unit 42.
