Passwords end up in AI chats
Engineers paste error messages to get help. Those messages often contain company passwords, which are then stored by an outside AI company.
Passwords are removed before anything is sent.
built for teams running coding agents
Rechazo AI is coding agent security that sits between your engineers and the agents they work with: Claude Code, Codex, Gemini CLI, Cursor and Copilot. It inspects every prompt, watches every action an agent takes, and keeps credentials out of the conversation, so your whole company can use AI agents safely.
What can go wrong when AI agents work inside your company, and how Rechazo handles each one.
When an engineer uses an AI agent, it logs in as them: cloud, code, payments, customer data. If the agent leaks a password or gets tricked, all of it is exposed.
Each line is a door the agent can open, with nobody checking.
Rechazo stands between the agent and every system, and checks each action first.
Open access: nothing checks what the agent does
Your engineer's AI agent
Rechazo runs on every engineer's laptop, right beside their AI agent. It covers five areas without changing how anyone works.
Engineer's laptopinside your limits
Engineer's laptopinside your limits
No change to how engineers work. They keep the agent they like; Rechazo runs alongside it on every laptop.
Roll it out with the device management you already use. It runs quietly next to each engineer's agent.
Engineers keep their agent. Nothing new to learn.
Start from sensible defaults and switch rules on or off. Changes reach every laptop in seconds.
Security sees what was stopped and why. Engineering sees how agents are being used across the team.

Checked in memory
Prompts are checked as they pass through. Keys are removed before anything is saved.
Decisions, not conversations
By default we keep what was decided, not what was said. You choose if, and how long, to keep more.
Never used for training
Your prompts, code and keys are never used to train any model.
Database URLs, cloud credentials, API tokens and webhooks. Rechazo keeps them out of prompts and scoped to the commands that need them, across every system your AI agents touch. How to keep API keys out of AI coding agents

FAQ
Rechazo AI (rechazo.si, also written Rechazo) is an AI coding agent security company. The name is Spanish for "rejection": Rechazo rejects the small fraction of prompts and agent actions that should not happen, so the rest can happen freely. It inspects every prompt before it leaves the company, stops risky agent actions on the machine and keeps credentials out of the conversation.
AI coding agent security is the set of controls that keep tools like Claude Code, Codex, Gemini CLI, Cursor and Copilot from leaking secrets, source code or customer data, and from taking risky actions on a developer machine. It covers what goes into prompts, what the agent is allowed to run, and which tools and MCP servers it can reach.
Read the AI coding agent security guideRechazo sits between your engineers and their agents and inspects each prompt before it leaves the company. Credentials, keys and sensitive values are caught in the prompt, so they can be redacted or the prompt blocked, rather than being sent to a model provider.
Rechazo works with all the major AI coding agents, including Claude Code, Codex, Gemini CLI, Cursor and Copilot, and teams can run several side by side.
Agent detection and response watches what an AI agent actually does on the machine, such as commands it runs, files it reads, and MCP servers or skills it loads, and can stop a risky action before it runs. It complements prompt inspection, which only sees what is sent to the model.
Read the AI agent runtime security guideNo tool can promise to eliminate prompt injection. Rechazo limits the damage: it keeps credentials out of the conversation and enforces policy on the actions an agent is allowed to take, so a hijacked agent has less to steal and less it can do.
Read the Prompt injection guideNo. Rechazo works with the controls the agent already ships with, such as permissions and managed settings, and adds inspection, enforcement and an audit trail across the whole company.
Read the Claude Code security guideIt can be, with the right configuration. Claude Code enforces permission rules in the tool rather than the model, lets administrators push managed settings that developers cannot override, can sandbox shell commands at the operating-system level and can restrict MCP servers to an allowlist. None of those inspects what a developer pastes into a prompt, and each covers Claude Code only.
Read the Claude Code security guideDeny the agent access to secret files in each tool's settings, such as Read deny rules in Claude Code, remove secrets from the environment that agent commands inherit, and give agents short-lived, narrowly scoped tokens. Deny rules alone are not enough, because shell commands and scripts can still reach files and environment variables.
Read the guide to keeping secrets out of AI coding agentsMCP security is deciding which Model Context Protocol servers a coding agent may connect to, what each one can reach, and how you notice when one changes after approval. The main risks are instructions hidden in tool descriptions, definitions that change after review, over-scoped tokens and local servers running with the developer's own privileges.
