    The Picari read

    Prompt Security provides runtime controls for GenAI and agentic AI, including prompt-injection blocking, MCP inspection, output filtering, and policy enforcement at the gateway layer. Its main differentiator is in-flight protection for both LLM apps and autonomous agents, making it a fit for enterprises that need guardrails on live AI interactions rather than static AI inventory.

    • CISOs and security teams requiring centralized governance and real-time security for Generative AI usage across their enterprise.
    • Preventing prompt injection attacks in enterprise LLM applications.
    • Enforcing data controls for sensitive information shared with GenAI tools.
    • Monitoring and auditing employee use of public and custom AI tools.
    • Securing AI agent interactions and their access to enterprise resources.
