What is AgentFortress?

As AI agents gain access to sensitive tools, databases, APIs, and filesystems, the attack surface explodes. A single compromised prompt can instruct your agent to exfiltrate data, bypass access controls, or execute destructive commands.

AgentFortress is a security layer that wraps your AI agents and watches everything:

• 🔍 Monitors every tool call, prompt, and response in real time
• 🚨 Detects prompt injection, PII leakage, data exfiltration, jailbreaks, and scope creep
• 🛑 Blocks threats before they cause damage, with configurable policies
• 📋 Audits every action with cryptographically signed, tamper-proof logs
• 🎬 Replays any session frame-by-frame for incident investigation
• 📊 Visualizes your security posture in a real-time SOC dashboard

Quick Start

Python

# Wrap your LangChain agent
from langchain.agents import AgentExecutor

# Listen for threats

    # page on-call, log to SIEM, etc.

JavaScript / TypeScript
