Security for AI coding agents

Let agents build. We hold the door.

  • 99.99%·Uptime
  • Low·Threat level

RAKSYON checks every prompt, tool call, package and diff your coding agents produce, before any of it reaches your repo, your keys or production.

The exposure

Coding agents read untrusted text, run shell commands and install packages with your credentials. Most security teams see none of it.

One Claude Code session, 41 minutes, 212 events. Three of them should never have run.

Products

Every session passes four checkpoints. In the order an agent works.

Each product runs on its own. Together they cover what an agent reads, what it runs, what it installs and what it leaves behind.

01

Warden

Before the prompt

Scans everything an agent reads, from issues and READMEs to web pages and MCP tool output, for injected instructions. Secrets and customer data are stripped before they enter the context window.

02

Portcullis

Before the shell

A policy engine on every tool call. Shell commands, file writes and network egress are allowed, denied or sent to a human for one-tap approval, with rules your team writes once.

03

Sieve

Before the install

Checks every package an agent adds against registry history, provenance and known malware, and catches hallucinated package names before someone registers them.

Logbook

After the merge

A signed, replayable record of each session: prompts, tool calls, diffs and approvals, tied to the commit it produced. Answer the auditor's question in one search.

Install

One command. Every agent covered.

RAKSYON installs as native hooks in Claude Code and Codex, as an MCP gateway for every other agent, and as a check in CI. Policies live in your repo and get reviewed like code.
