prompt security

Prompt Security provides security solutions designed to protect AI applications and agentic systems from prompt injection attacks and other AI-specific threats. The company focuses on securing large language model (LLM) implementations, including homegrown AI applications, RAG pipelines, and autonomous agents that operate across enterprise environments. Their platform offers context-aware protections that analyze multi-turn conversations and detect threats that span multiple interactions, addressing attacks that traditional single-prompt security measures cannot identify. The company's research has demonstrated vulnerabilities in AI systems including embedding-level prompt injection in RAG pipelines, dependency hijacking through marketplace skills, and goal hijacking via hidden instruction layers in development environments. Prompt Security addresses security challenges that emerge as AI systems transition from assistive tools to autonomous agents with persistent access to organizational systems. Their approach includes real-time monitoring, policy enforcement, and visibility into AI application behavior. The platform is designed for enterprises deploying AI applications that require operational controls, particularly in environments where AI agents have access to sensitive data, execute actions autonomously, or integrate with multiple business systems. The company conducts ongoing research into AI security vulnerabilities and publishes findings on emerging attack vectors in agentic AI systems, LLM-powered applications, and AI development tools.
