Secure the AI agents your scanner can't see.
Autonomous agents call tools, touch sensitive data, and make decisions — usually with zero oversight. PostureGuard discovers every agent and MCP server, monitors them live, and catches prompt injection in real time.
Your fastest-growing attack surface is invisible.
Traditional CSPM and ASPM tools see infrastructure and code. They are blind to what your AI agents actually do at runtime — which tools they call, what data they reach, and when they're hijacked by prompt injection. As teams ship agentic features, this gap widens daily.
One platform, mapped to your need.
PostureGuard is an AI-era security posture platform that maps your entire attack surface — infrastructure, identity, and AI agents — on one visual canvas, scores it, and proves compliance from blueprint to runtime.
Discover every agent
Auto-detect agents, MCP servers, and LLM endpoints — including shadow AI nobody told security about.
Live decision replay
Step through exactly what an agent did, when, and why — audit-grade visibility into autonomous behavior.
Prompt-injection defense
Detect and block injection attempts in real time, and tie each agent to its bound identity and blast radius.
Built for the AI era, not retrofitted.
PostureGuard treats the AI runtime as a first-class layer of your attack surface — mapped on the same canvas as infrastructure and identity, scored, and connected to compliance. This is what defines AI-era security posture management.
What teams ask
AI agent security is the practice of discovering, monitoring, and governing autonomous AI agents — including the tools they call, the identities they use, and the data they access — to prevent misuse, prompt injection, and data exposure.
PostureGuard instruments agents via a lightweight SDK and monitors their tool invocations and inputs in real time, flagging and blocking injection attempts as they happen.
An MCP (Model Context Protocol) server exposes tools and data to AI agents. PostureGuard discovers MCP servers and maps what each agent connected to them can reach.
A 3-line Capture SDK gives full decision-replay visibility, but PostureGuard can also auto-discover agents and AI services from your cloud and identity providers.
