Arcjet

In plain words

Arcjet is a runtime security platform designed for developers building AI agents. It detects prompt injection attacks, authorizes tool calls, redacts sensitive data, and blocks bots and abuse through real-time security controls integrated directly into application code. The platform helps organizations discover running agents, enforce security policies across actions and prompts, and maintain audit records of what occurred.

  Hi HN, Fernando and I built Kastra. Kastra intercepts AI agent tool calls and evaluates them against deterministic policies before they execute. We built this product to control pre- and post-inference workloads. This is aimed at developers using coding agents like Claude Code, Codex, Cursor, and OpenClaw. Kastra pushes an allow, hold, and deny decision before the action runs. You can build these policies in plain English from the web app. The interception engine evaluates the tools, targets, and parameters of every action at sub 1ms at a scale of billions of interceptions per day. We also…
