OpenClaw Security: How Safe is Your AI Agent? (2026)

OpenClaw runs entirely on your machine, which gives you full control over security. This guide covers everything you need to know about securing your agents, protecting API keys, locking down the gateway, and following best practices for safe deployment.

Is OpenClaw Safe to Use?

Yes. OpenClaw is open-source, self-hosted, and fully auditable. Unlike cloud-based agent platforms that route your prompts and data through third-party servers, OpenClaw runs on your own hardware. Your conversations, agent configurations, and session data never leave your machine unless you explicitly configure external integrations.

The entire OpenClaw codebase is available on GitHub. Anyone can inspect the source code, verify what data is transmitted, and confirm there are no hidden telemetry or data collection mechanisms. This level of transparency is the gold standard for security-conscious users and organizations.

The only external calls OpenClaw makes are to the LLM provider you configure (Anthropic, OpenAI, Google, or a local Ollama instance). If you run Ollama with a local model, your entire agent stack operates without any internet connection at all.

Self-Hosted = You Control Your Data

The most significant security advantage of OpenClaw is its self-hosted architecture. When you run an agent on a cloud platform, you are trusting that provider with your data, their encryption practices, their employee access controls, and their data retention policies. With OpenClaw, you eliminate every one of those trust dependencies.

Here is what stays on your machine:

Agent configurations (SOUL.md)

Your agent identity, rules, personality, and skills definitions are stored as markdown files in your local filesystem. They are never uploaded anywhere.

Conversation history

All chat sessions and message logs are stored locally in the OpenClaw sessions directory. No third-party server stores or indexes your conversations.

Gateway state

The gateway process, routing tables, and agent registry all run in memory and on disk on your machine. There is no external control plane.

Integration credentials

Telegram bot tokens, Slack tokens, and other integration credentials are stored in your local .env files, not in any remote database.

This architecture means you can deploy OpenClaw agents in environments with strict data residency requirements, air-gapped networks, or compliance frameworks that prohibit sending data to external services.

API Key Security

API keys are the most sensitive piece of your OpenClaw setup. They grant access to LLM providers and cost real money if compromised. OpenClaw uses environment variables to manage keys, which keeps them out of your configuration files and version control.

Correct: API keys in .env file
# agents/researcher/.env
ANTHROPIC_API_KEY=sk-ant-...
OPENAI_API_KEY=sk-...

# Never commit this file
# .gitignore should include:
# .env
# .env.local
# .env.*.local
Wrong: API keys hardcoded in SOUL.md
# DO NOT do this
## Identity
- Name: Researcher
- API Key: sk-ant-abc123...  # NEVER put keys here

OpenClaw reads environment variables from the .env file in your agent workspace at startup. The keys are loaded into memory and never written to logs or session files. Always add .env to your .gitignore before your first commit to prevent accidental exposure.

If you manage multiple agents, each can have its own .env file with separate API keys. This lets you use different keys for different agents, track usage per agent, and revoke access to a single agent without affecting others.

Gateway Security

The OpenClaw gateway is the central process that routes messages between users, agents, and channels. Securing the gateway is critical because anyone with access to it can interact with your agents and potentially trigger actions through their skills.

Token Authentication

The gateway supports token-based authentication. When enabled, every request to the gateway must include a valid bearer token. Requests without a token or with an invalid token are rejected.

Gateway token authentication
# Set gateway auth token in .env
OPENCLAW_GATEWAY_TOKEN=your-secure-random-token

# All API requests must include the token
curl -H "Authorization: Bearer your-secure-random-token" \
  http://localhost:18789/api/agents

Loopback Binding (Default)

By default, the gateway binds to 127.0.0.1 (loopback), which means it only accepts connections from your local machine. No other device on your network, and no one on the internet, can reach it. This is the safest configuration and the right default for most users.

Optional Tailscale Integration

If you need remote access to your gateway (for example, to reach your agents from a phone while away from your desk), the recommended approach is Tailscale. Tailscale creates an encrypted WireGuard tunnel between your devices without opening any ports to the public internet. You bind the gateway to your Tailscale IP, and only devices on your tailnet can connect.

Gateway bind modes
# Default: loopback only (most secure)
openclaw gateway start
# Binds to 127.0.0.1:18789

# LAN access: bind to all interfaces
openclaw gateway start --host 0.0.0.0
# Accessible from any device on your local network

# Tailscale: bind to tailnet IP (recommended for remote)
openclaw gateway start --host 100.x.x.x
# Only accessible from your Tailscale network

Agent Permissions

OpenClaw uses an explicit permissions model through its skills system. An agent can only perform actions that are explicitly granted in its SOUL.md file. If a skill is not listed, the agent cannot use it. There is no implicit access to anything.

Agent with limited permissions
# Content Writer Agent - SOUL.md

## Identity
- Name: Writer
- Role: Blog content writer

## Skills
- browser: Research topics on the web

# This agent CANNOT:
# - Read or write files (no filesystem skill)
# - Execute code (no code_runner skill)
# - Send emails (no email skill)
# - Access databases (no database skill)
# Only the browser skill is available

This principle of least privilege is a security fundamental. Give each agent only the skills it needs to do its job. A content writer does not need filesystem access. A research analyst does not need code execution. An SEO agent does not need email sending capabilities.

Review your SOUL.md files periodically to ensure agents do not accumulate unnecessary permissions over time. Treat SOUL.md as a security document as much as a configuration file.

Network Security

The gateway bind mode determines who can reach your agents over the network. OpenClaw supports three bind modes, each with different security implications:

Bind ModeAddressWho Can ConnectUse Case
Loopback127.0.0.1Only your machineDevelopment, personal use
LAN0.0.0.0Any device on your networkTeam use on trusted network
Tailnet100.x.x.xOnly your Tailscale devicesSecure remote access

Never expose the gateway to the public internet by binding to 0.0.0.0 on a machine with a public IP and no firewall. If you need internet-accessible agents, put the gateway behind a reverse proxy (nginx or Caddy) with TLS termination, rate limiting, and authentication.

For most users, the default loopback binding combined with Telegram or Slack channel integration provides the ideal balance. The gateway stays locked to localhost, and your agents are accessible through the messaging app on your phone, which connects through the channel provider rather than directly to your gateway.

Security Best Practices Checklist

Follow this checklist to ensure your OpenClaw deployment is secure. Each item addresses a specific attack surface or common misconfiguration:

Store API keys in .env files, never in SOUL.md

Environment variables are loaded into memory at startup and never written to logs. SOUL.md files are plain text that can be accidentally shared or committed to version control.

Add .env to .gitignore before your first commit

A single accidental commit of a .env file exposes your API keys in git history permanently. Even if you delete the file later, the keys remain in the commit history. Add the gitignore rule first.

Rotate API keys periodically

Set a reminder to rotate your LLM provider API keys every 90 days. If a key is compromised, the window of exposure is limited. Use separate keys for each agent so you can revoke individual access.

Keep the gateway on loopback unless you need remote access

The default 127.0.0.1 binding is the most secure option. Only change it if you have a specific need, and prefer Tailscale over 0.0.0.0 when you do.

Enable gateway token authentication

Even on loopback, token auth prevents other local processes or malicious scripts from interacting with your agents. Set OPENCLAW_GATEWAY_TOKEN in your environment.

Grant agents only the skills they need

Review each SOUL.md and remove skills that are not essential for the agent's role. A content writer does not need code execution. A researcher does not need filesystem write access.

Audit SOUL.md files regularly

Treat SOUL.md as a security policy document. Review agent rules, skills, and personality sections periodically. Look for overly broad instructions that could lead to unintended agent behavior.

Use Ollama for maximum privacy

If your workflow allows it, run a local model through Ollama. This eliminates all external API calls, meaning zero data leaves your machine. Ideal for sensitive environments.

Security vs Cloud Alternatives

How does OpenClaw's security model compare to cloud-based AI agent platforms? Here is a direct comparison across the dimensions that matter most:

Security DimensionOpenClaw (Self-Hosted)Cloud Platforms
Data residencyYour machine, your jurisdictionProvider's data centers
Source code auditFully open-source, auditableProprietary, trust the vendor
Third-party accessNone (unless you configure it)Provider employees, subprocessors
Conversation loggingLocal files onlyProvider's logging infrastructure
Network exposureLoopback by defaultInternet-facing by design
Credential storageLocal .env filesProvider's secrets manager
Offline operationYes (with Ollama)No
Security responsibilityYou manage everythingProvider manages infrastructure

The tradeoff is clear. OpenClaw gives you maximum control and privacy, but you are responsible for hardening your own setup. Cloud platforms handle infrastructure security for you, but you must trust them with your data. For individuals and teams that handle sensitive information, the self-hosted model is often the only acceptable option.

Frequently Asked Questions

Is OpenClaw safe to use?

Yes. OpenClaw is an open-source, self-hosted framework. Your data never leaves your machine unless you explicitly configure it to. The source code is publicly auditable on GitHub, and the gateway runs locally by default. You control every aspect of the security posture, from network binding to API key storage to agent permissions.

Does OpenClaw send my data to any cloud service?

OpenClaw itself does not send data to any cloud service. The only external communication happens when your agent calls an LLM API (such as Anthropic, OpenAI, or Google). If you use Ollama for local inference, no data leaves your machine at all. The gateway, agent configurations, and session data all remain on your local filesystem.

How do I secure my API keys in OpenClaw?

Store all API keys in a .env file in your agent workspace directory. OpenClaw reads environment variables from this file at startup. Never hardcode keys in your SOUL.md file. Add .env to your .gitignore to prevent accidental commits. Rotate keys periodically and use separate keys for development and production environments.

Can someone access my OpenClaw gateway from the internet?

Not by default. The OpenClaw gateway binds to 127.0.0.1 (loopback) out of the box, which means it only accepts connections from your local machine. To allow LAN access, you must explicitly change the bind address. For remote access, the recommended approach is Tailscale, which creates an encrypted tunnel without exposing any ports to the public internet.

What permissions do OpenClaw agents have?

OpenClaw agents can only use the skills explicitly listed in their SOUL.md file. If you do not grant the browser skill, the agent cannot browse the web. If you do not grant the filesystem skill, the agent cannot read or write files. This explicit permission model means agents are sandboxed to the capabilities you define.

Is OpenClaw more secure than cloud-based AI agent platforms?

For data privacy, yes. With OpenClaw, your prompts, agent configurations, and conversation history never pass through a third-party server. Cloud platforms require you to trust the provider with your data, their infrastructure security, and their data retention policies. The tradeoff is that you are responsible for your own security hardening, whereas cloud platforms handle infrastructure security for you.
