Enterprise LLM applications introduce new security risks at the point where users, AI agents, APIs, and model-serving platforms interact. Prompt injection, unauthorized model access, sensitive-data exposure, denial-of-service attacks, and insecure backend connectivity require security controls that extend beyond traditional application boundaries. This session presents a vendor-neutral zero-trust edge architecture for protecting enterprise LLM and generative AI workloads. The framework is built around four core security primitives: globally distributed edge gateways with DDoS protection, Web Application Firewall enforcement, private connectivity to model endpoints, and end-to-end TLS with mutual authentication. Attendees will learn how these controls can secure LLM APIs, retrieval-augmented generation pipelines, AI agents, and inference services while supporting identity-aware access, regional data restrictions, and secure communication between application and model layers. The session also examines residual risks, including prompt injection, model abuse, compromised dependencies, certificate-management challenges, and insider threats. The architecture is mapped across Microsoft Azure, AWS, Google Cloud, and Cloudflare to demonstrate how organizations can implement consistent protections across multi-cloud AI environments. The session concludes with practical guidance on secure Infrastructure-as-Code templates, continuous policy tuning, private endpoint management, certificate lifecycle automation, and monitoring for suspicious LLM traffic patterns.
