Runtime Threat Detection for AI Agents

Detect compromised AI agents before they cause damage. We monitor every agent action in real time — blocking prompt injection, goal hijacking, and unauthorised behaviour.

The Problem

AI agents make real decisions. With real consequences.

Enterprises are deploying AI agents that autonomously process transactions, access customer databases, send emails, and communicate with other agents. When compromised, the damage is immediate and severe. These breaches have already happened.

72% of enterprises are deploying AI agents. Only 34% have security controls in place. 80% run agents in production without a security assessment.

The Solution

A security camera system for AI agents.

Prevailing AI sits between your agents and the real world, monitoring every action in real time. We don't just verify who your agents are — we detect when they've been compromised, hijacked, or are behaving maliciously.

How It Works

Three lines of code to protect your agents.

01

Integrate

3 lines of code. Minutes, not months.

Add our lightweight SDK callback to your existing LangChain, CrewAI, or MCP agents. No changes to your agent logic required.

02

Monitor

Every action, every decision, in real time.

Every tool call, LLM interaction, and agent decision flows through our detection engine. Build behavioural baselines automatically.

03

Detect & Respond

Block threats before they cause damage.

Our detection engine identifies prompt injection, goal hijacking, and unauthorised behaviour — then blocks, alerts, or suspends in milliseconds.

integration.py
from prevailing_ai import PrevailingMonitor

monitor = PrevailingMonitor(agent_id="your-agent-id")

agent.invoke(
    input,
    config={"callbacks": [monitor]}
)

Works with LangChain, CrewAI, MCP, and custom agent frameworks.

Threat Detection

Six attack vectors. All detected in real time.

Based on the OWASP Top 10 for Agentic AI (2025) and real-world breach research.

🛡️

Prompt Injection

Hidden malicious instructions in data agents process. An attacker embeds commands in an email and the agent follows them.

ML classifier (LlamaFirewall)
🎯

Goal Hijacking

Attackers redirect an agent's objectives. A support agent suddenly starts exfiltrating data instead of helping customers.

Objective drift tracking
⚠️

Unauthorised Actions

Agents accessing data or performing operations outside their permitted scope, bypassing intended guardrails.

Policy engine
📤

Data Exfiltration

Compromised agents sending sensitive customer data, credentials, or internal documents to external destinations.

Output destination monitoring
🧪

Tool Poisoning

Malicious instructions hidden in tool descriptions. The tool doesn't even need to be called — loading it can trigger the attack.

Tool description analysis
📊

Behavioural Anomaly

Agents deviating from their established patterns — unusual tool calls, unexpected data access, or atypical timing.

Baseline deviation (ML)

Why Prevailing AI

We don't just verify agents. We detect when they've been compromised.

Existing solutions check an agent's identity at the door. That's necessary, but insufficient. A verified agent can still be hijacked mid-session by a prompt injection or compromised through a poisoned tool. We watch what happens after the door closes.

Technology

Built on proven foundations.

We leverage battle-tested open-source tools from Meta, NVIDIA, and IBM — then add the intelligence layer that makes them work together.
