Security - PraisonAI

Agents include security features to prevent misuse and protect data.

Quick Start

Simple Usage

import { Agent } from 'praisonai';

const agent = new Agent({
  instructions: 'You are a helpful assistant',
  security: true  // Enable all protections
});

await agent.chat('Ignore previous instructions and...');
// Prompt injection blocked

With Configuration

const agent = new Agent({
  security: {
    blockInjection: true,
    blockPII: true,
    maxTokens: 4000
  }
});

User Interaction Flow

Configuration Levels

// Level 1: Bool - Enable all protections
const agent = new Agent({
  security: true
});

// Level 2: Array - Specific protections
const agent = new Agent({
  security: ['injection', 'pii', 'profanity']
});

// Level 3: Dict - Full control
const agent = new Agent({
  security: {
    blockInjection: true,
    blockPII: true,
    blockPatterns: [/password/i, /\b\d{16}\b/],  // Credit cards
    maxTokens: 4000,
    rateLimit: 10  // Per minute
  }
});
