# Agent Guard

## Introduction

Akto's Agent Guard provides a comprehensive security layer for AI-powered applications through intelligent scanners that detect and prevent threats in real-time. This reference guide covers all scanners available in the Agent Guard system.

## What are Guardrail Scanners?

Guardrail scanners are specialized security modules that analyze content flowing through your AI systems. They act as intelligent checkpoints 🔍, examining both user inputs and AI-generated outputs to identify security threats, policy violations, data leaks, and content safety issues before they cause harm.

## How Guardrails Work

Akto's Agent Guard operates on a dual-layer approach:

* **Input Layer**: Scanners validate user messages before they reach your AI models, blocking malicious prompts, credential leaks, and policy violations
* **Output Layer**: Scanners verify AI-generated responses before delivery to users, preventing data exposure, harmful content, and compliance violations

Each scanner specializes in detecting specific guardrail categories, from credential exposure and prompt injection attacks to toxic content and sensitive data leaks. Scanners can be combined to create custom security policies tailored to your application's needs.

## When to Use Which Scanners

**🤖 For Agentic Applications**:

* Use input scanners to protect your AI endpoints from malicious prompts
* Use output scanners to prevent your AI from exposing API vulnerabilities or credentials

**👥 For Customer-Facing Applications**:

* Deploy content safety scanners (Toxicity, Bias, BanTopics) to maintain appropriate communication
* Enable PII detection scanners (Sensitive, Secrets) to ensure privacy compliance

**🏢 For Enterprise AI Systems**:

* Implement comprehensive scanner suites covering security, compliance, and content policies
* Layer multiple scanners for defense-in-depth protection

## Scanner Categories

This guide organizes scanners into two main categories:

* **📥 Input/Prompt Scanners**: Protect against threats in user messages
* **📤 Output Scanners**: Ensure safety and compliance in AI responses

Each scanner entry includes its purpose, detection capabilities, risk prevention benefits, real-world use cases, and example detections.

## Custom Policies

You can create Custom Policies to define application-specific guardrails beyond the default scanners. These policies allow you to control agent behavior across inputs, outputs, and tool execution based on your requirements.

#### Overview

A Custom Policy consists of:

* **Rules** - conditions evaluated on inputs, outputs, or actions
* **Actions** - enforcement applied when conditions are met

You can configure policies to run during request and response processing within Agent Guard.

#### Where Policies Apply

You can apply Custom Policies at:

* Input scanning (before execution)
* Output scanning (after execution)
* Tool execution (during actions)

#### What You Can Do

* Define rules based on request or response content
* Enforce role-based or context-aware restrictions
* Control tool access and execution
* Update policies without changing agent logic

#### Enforcement

When a policy condition is met, you can:

* Allow
* Modify
* Restrict
* Block

Multiple policies can be combined to enforce layered controls. See: [create-guardrail-policies](https://ai-security-docs.akto.io/agentic-guardrails/how-to/create-guardrail-policies "mention") to learn more.
