Arcjet: The Security Guard for Your AI Agents

Product Introduction

AI agents are popping up everywhere—coding assistants, internal chatbots, you name it. But with great power comes great risk. Who's making sure these agents don't go rogue? Enter Arcjet, a runtime security platform built specifically for AI agents. It automatically discovers agents running in your organization and enforces policies on every action, prompt, and tool call. And it keeps a complete evidence trail, so you're never left in the dark.

Key Features

Prompt Injection Detection
Every prompt your agent receives gets scanned in real time. If something smells like a malicious injection, Arcjet blocks it before it can hijack instructions or leak data. Think of it as a spam filter, but for AI commands.

Tool Call Authorization
Before your agent executes a tool call, Arcjet checks if it's allowed based on context and policies. No more unauthorized access to internal systems or sensitive operations. It's like having a permission slip for every action.

Malicious Destination & MCP Server Detection
Arcjet analyzes external targets and Model Context Protocol (MCP) servers your agent tries to reach. If it spots a high-risk connection, it slams the door shut. Prevents data exfiltration and other nasty surprises.

PII Redaction & Sensitive Data Detection
Automatically detects personal identifiable information (PII) and sensitive data in prompts and responses. It can redact or block on the fly, helping you stay compliant with GDPR, PCI, and other privacy regs. No more accidental leaks.

Bot & API Abuse Protection
Using fingerprints and risk signals, Arcjet tells real users from bots. Protects your agent APIs from scraping, credential stuffing, and other abuse. Keeps your service available and fair.

Rate Limiting & Quota Management
Set smart rate limits per user, session, or tenant. Prevents resource exhaustion and ensures everyone gets a fair share. No more noisy neighbors.

Audit Evidence & SIEM Export
Records every action, decision, and policy enforcement. Seamlessly exports to SIEM platforms for security investigations and compliance audits. Full transparency, zero guesswork.
