OpenClaw Security Hardening Guide for VPS Deployments

OpenClaw is powerful because it can connect to tools, files, browsers, APIs, messaging platforms, and automation workflows. That power also makes security important. If OpenClaw is deployed on a VPS, the server may hold agent state, workspace files, logs, credentials, browser sessions, and remote access settings.

The safest OpenClaw VPS setup is private by default: keep the Gateway on loopback or a private network, access it through SSH tunnel, Tailscale, WireGuard, or VPN, use a long random Gateway token, enable firewall rules, keep OpenClaw updated, and run one Gateway per trust boundary.

Quick OpenClaw Security Checklist

• Keep the OpenClaw Gateway private whenever possible.
• Access the Gateway through SSH tunneling, Tailscale, WireGuard, or VPN.
• Do not expose the Gateway directly to the public internet.
• Use a long random Gateway token or strong authentication.
• Use SSH keys instead of password-based SSH login.
• Disable direct root password login when possible.
• Enable a firewall and allow only required ports.
• Run OpenClaw under a dedicated Linux user.
• Use one Gateway per trust boundary.
• Enable sandboxing for tool execution where possible.
• Do not give agents unnecessary shell, filesystem, browser, or network access.
• Use dedicated browser profiles for OpenClaw automation.
• Do not use personal browser or password manager profiles in a shared OpenClaw runtime.
• Protect API keys, tokens, state files, workspace files, and logs.
• Back up OpenClaw state and workspace data regularly.
• Run openclaw security audit after installation and configuration changes.

Why OpenClaw Needs Security Hardening

OpenClaw should not be treated like a basic public website. An OpenClaw agent may be able to execute tools, send messages, read files, write files, automate a browser, call APIs, and act on behalf of a user or business workflow.

If an attacker gains access to the OpenClaw Gateway, agent tools, browser profile, or credentials, the impact may include:

• Exposure of OpenClaw configuration files.
• Exposure of API keys, model provider credentials, bot tokens, or integration secrets.
• Access to workspace files, logs, transcripts, and generated output.
• Unauthorized agent commands.
• Abuse of messaging platforms connected to OpenClaw.
• Browser session abuse if OpenClaw controls a logged-in browser profile.
• Unwanted file changes, command execution, or data exfiltration.

The goal is not to make every agent workflow risk-free. The goal is to limit exposure, reduce blast radius, and give OpenClaw only the access it needs.

Use One Gateway Per Trust Boundary

OpenClaw's security model is best understood as one trusted operator boundary per Gateway. A trust boundary is a group of users, agents, credentials, browser profiles, files, and tools that are allowed to share the same delegated authority.

For personal use, one user can run one Gateway on one VPS. For business use, one team can share a Gateway only if everyone belongs to the same trust boundary and the agent is business-only.

Do not use one shared OpenClaw Gateway for mutually untrusted users, different customers, unrelated teams, or adversarial users. If users should not share credentials, browser profiles, workspace files, or tools, split the deployment.

Recommended isolation patterns include:

• Separate VPS instances for different users, teams, or customers.
• Separate OpenClaw Gateways for different trust boundaries.
• Separate Linux users for different deployments on the same server.
• Separate credentials, bot tokens, browser profiles, and workspace directories.
• Separate backups and logs for each environment.

Keep the OpenClaw Gateway Private

The Gateway is the most important surface to protect. It controls state, workspace access, device pairing, tool execution, and communication between clients and nodes.

The secure default is to keep the Gateway bound to loopback and access it privately. That means the Gateway listens only on the VPS itself and is reached through a secure tunnel or private network.

Preferred access methods include:

• SSH tunnel from your local machine to the VPS.
• Tailscale private network access.
• WireGuard VPN access.
• Private management network where available.

Avoid exposing the Gateway directly on a public IP address. If you must bind the Gateway to a LAN, tailnet, or other non-loopback interface, require Gateway token or password authentication and restrict access with firewall rules.

Use Strong Gateway Authentication

Gateway authentication should use a long, random token or another strong authentication method. Do not rely on a short human-created password for an automation system that can control tools, files, APIs, messaging channels, and browser sessions.

A good Gateway token should be:

• Long.
• Randomly generated.
• Unique to that OpenClaw deployment.
• Stored securely.
• Rotated if exposed.
• Not reused across other services.

Do not paste Gateway tokens into public tickets, chat rooms, screenshots, or documentation. If a token may have been exposed, rotate it immediately and review logs for unexpected connections or device registrations.

Secure SSH Access to the VPS

Because the VPS hosts OpenClaw state and configuration, SSH access must be hardened. If an attacker gains SSH access, they may be able to read OpenClaw files, modify configuration, steal tokens, change tools, or inspect logs.

Recommended SSH hardening steps:

• Use SSH keys instead of passwords.
• Disable password login when possible.
• Disable direct root password login when possible.
• Use a dedicated administrative user with sudo privileges.
• Restrict SSH access by IP address when practical.
• Keep OpenSSH updated.
• Use fail2ban or equivalent protection for repeated login attempts.

Example SSH configuration options:

PasswordAuthentication no
PermitRootLogin no
PubkeyAuthentication yes

After changing SSH configuration, keep your current SSH session open and test a second session before closing the first one. This helps prevent accidental lockout.

Enable a Firewall

A VPS running OpenClaw should use a default-deny firewall posture. Only required services should be reachable from the public internet. For many OpenClaw VPS deployments, SSH is the only public port that needs to be open.

Example UFW baseline:

sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw allow OpenSSH
sudo ufw enable
sudo ufw status verbose

If you use Tailscale, WireGuard, or another private network, allow OpenClaw access only through that private interface. Do not open the OpenClaw Gateway port to the public internet unless you have strong authentication, TLS, firewall restrictions, logging, and monitoring in place.

Run OpenClaw Under a Dedicated Linux User

Do not run OpenClaw as root unless there is a specific reason and you understand the implications. A dedicated Linux user helps limit accidental access to system-wide files and makes it easier to manage permissions, logs, backups, and service ownership.

Example:

sudo adduser openclaw
sudo usermod -aG docker openclaw

Use the dedicated user for OpenClaw application files, workspace data, configuration, runtime services, and related scripts.

Keep OpenClaw Updated

Keeping OpenClaw updated is a security requirement. Updates may include vulnerability fixes, authentication improvements, Gateway changes, sandboxing improvements, and safer defaults.

Check your installed version:

openclaw --version

After updating OpenClaw, restart the Gateway and run a security audit.

openclaw security audit
openclaw security audit --deep

If you run OpenClaw through Docker Compose, use the CLI container for audit commands when appropriate:

docker compose run --rm openclaw-cli security audit
docker compose run --rm openclaw-cli security audit --deep

Run OpenClaw Security Audits

OpenClaw includes a security audit command that checks for common risky configuration patterns. Run it after installation, after exposing any network surface, after adding integrations, and after major configuration changes.

openclaw security audit
openclaw security audit --deep
openclaw security audit --json

If you want OpenClaw to apply narrow automatic fixes, review the output first and then use:

openclaw security audit --fix

The audit can help identify exposed Gateway authentication risks, browser control exposure, permissive execution approvals, open-channel tool exposure, unsafe file permissions, and logging redaction issues.

Enable Sandboxing for Tool Execution

Sandboxing reduces the blast radius of agent tool execution. When sandboxing is enabled, OpenClaw can run tool execution inside isolated environments rather than directly on the host.

Sandboxing is especially important when agents can:

• Run shell commands.
• Read and write files.
• Edit code or configuration.
• Use browser automation.
• Process untrusted content.
• Interact with customer files, public websites, or uploaded data.

Recommended sandboxing practices:

• Enable sandboxing for high-risk or non-owner sessions.
• Prefer per-agent or per-session sandbox scope over one shared sandbox.
• Avoid unnecessary host bind mounts.
• Do not mount secrets into sandbox containers unless required.
• Limit network access for sandboxed tools when possible.
• Review any elevated tools that bypass sandbox restrictions.

Sandboxing is not a perfect security boundary, but it is much safer than allowing every agent workflow to execute directly on the VPS host.

Limit Agent Tool Permissions

Do not give every agent full shell, filesystem, browser, and network access by default. Start with the smallest permission set that allows the workflow to function.

Useful permission patterns include:

• Read-only agents for research or monitoring tasks.
• Agents without shell access for messaging-only workflows.
• Restricted workspace directories instead of full filesystem access.
• Separate agents for sensitive and non-sensitive workflows.
• Manual approval for destructive or high-risk actions.

Review any tool that can execute commands, write files, delete files, access secrets, send messages externally, control a browser, call internal APIs, or reach private networks.

Harden Browser Automation

Browser automation is one of the highest-risk OpenClaw features because a browser may already be logged into accounts, dashboards, email, cloud services, or internal applications. If an agent controls that browser, the agent may be able to act with the browser user's permissions.

Recommended browser hardening steps:

• Use a dedicated browser profile for OpenClaw.
• Do not use your personal daily browser profile for agent automation.
• Disable browser password managers in the agent profile.
• Disable browser sync in the agent profile where possible.
• Use isolated download directories.
• Treat downloaded files as untrusted.
• Do not expose browser control ports to the public internet.
• Keep browser control access on a private network or tunnel.

If OpenClaw controls a browser profile that is logged into business systems, treat that profile as sensitive production access.

Secure Messaging Channels and Group Access

If OpenClaw is connected to chat platforms or messaging channels, control who can talk to the agent and what the agent can do from each channel.

Recommended practices:

• Use pairing or allowlists for direct messages.
• Require explicit mentions in group chats.
• Do not allow every workspace member to trigger tool-enabled actions by default.
• Use separate bot accounts for personal and business workflows.
• Use separate agents for different teams or trust levels.
• Do not connect a shared team agent to personal accounts or personal browser profiles.
• Review chat logs for unexpected commands or repeated failed attempts.

Protect Logs, Transcripts, and Workspace Files

Logs and transcripts can contain sensitive information even when the main application is configured correctly. Agent conversations may include pasted secrets, file contents, internal URLs, API responses, command output, customer data, and operational details.

Recommended practices:

• Keep sensitive-data redaction enabled.
• Add custom redaction patterns for your environment.
• Do not share raw logs publicly.
• Restrict file permissions on logs and transcripts.
• Limit retention if long-term logs are not required.
• Back up only the logs and workspace files you actually need.
• Review troubleshooting output before sending it to support.

Back Up OpenClaw State and Workspace Files

In a VPS deployment, the server may own the OpenClaw state and workspace. If the VPS is deleted, corrupted, compromised, or misconfigured, you may lose agent state, configuration, logs, and files.

Back up:

• OpenClaw state directories.
• Workspace directories.
• Configuration files.
• Environment files.
• Docker Compose files and deployment scripts.
• Important logs and audit records.

Store backups securely. If a backup contains tokens, API keys, browser state, transcripts, or private files, treat it as sensitive production data.

Use DDoS Protection for Availability

DDoS protection does not replace application security, authentication, firewall rules, or Gateway hardening. However, it can help preserve availability for public-facing infrastructure and remote-access services.

Psychz cVirtual is a good fit for OpenClaw users who want an always-on VPS with NVMe storage, unmetered bandwidth, DDoS protection options, Linux control, and global data center choices.

Basic Incident Response Plan

If you suspect that your OpenClaw VPS, Gateway, token, agent, or integration has been compromised, act quickly.

1. Contain

• Stop the OpenClaw Gateway if needed.
• Block public access to exposed ports.
• Disable affected integrations.
• Revoke suspicious device pairings.
• Disconnect high-risk browser sessions.
• Preserve logs before rebuilding or deleting anything.

2. Rotate Secrets

• Rotate Gateway tokens.
• Rotate AI model provider API keys.
• Rotate bot tokens for messaging channels.
• Rotate OAuth credentials where applicable.
• Rotate any credentials that appeared in logs, transcripts, or workspace files.

3. Audit

• Review OpenClaw logs and transcripts.
• Check recent device registrations.
• Review shell history and system logs.
• Check for unexpected files, tools, plugins, or configuration changes.
• Run OpenClaw security audit.
• Review firewall rules and exposed ports.

4. Rebuild if Needed

If host compromise is likely, rebuild the VPS from a clean image instead of trying to repair it in place. Restore only trusted configuration and workspace data. Rotate secrets before bringing the deployment back online.

OpenClaw Security FAQ

Is OpenClaw safe to expose to the public internet?

In most cases, no. The safer approach is to keep the Gateway private and access it through SSH tunnel, Tailscale, WireGuard, or VPN.

What is the safest way to access OpenClaw on a VPS?

Keep the Gateway bound to loopback and access it through an SSH tunnel or private network. This avoids placing the Gateway directly on the public internet.

Should I run OpenClaw as root?

No. Run OpenClaw under a dedicated Linux user whenever possible. This helps limit the impact of mistakes, misconfigurations, or compromised workflows.

Does sandboxing make OpenClaw completely safe?

No. Sandboxing reduces risk, but it is not a perfect security boundary. You still need strong authentication, private access, updates, restricted tools, and protected secrets.
