nono
agent runtime security - zero trust, zero setup, zero latency agent sandboxing
No outside reports on file
Nono reduces risk but isn't a complete security solution; always audit what agents can do and assume some threat remains.
Based on public adoption and transparency signals as of Oct 21, 2026. Our opinion, not a code audit or security guarantee.

About Nono
Nono is a sandboxing tool designed to run AI agents in isolated environments with security built in from the start. It aims to limit what an agent can access and do, reducing the risk of harmful actions without needing complex setup or causing slowdowns.
Who it’s for
Developers building AI agent systems who want security guardrails without extra complexity. Teams concerned about agents accessing sensitive data or taking unintended actions.
Alternatives
- Anthropic's model context protocol: Built-in security patterns for Claude integrations
- Docker/container sandboxing: General-purpose isolation for agent workloads
- Temporal: Workflow engine with built-in execution limits and retry controls
- LangChain with tool approval: Framework-level restrictions on agent tool use
Setup
Check these steps against the project’s own instructions before running anything.
Follow the project's README. The GitHub repository (nolabs-ai/nono) should contain installation and configuration instructions specific to your use case.

Risks to watch for
- Sandbox escape: Any sandbox can potentially be bypassed; verify Nono's security model matches your threat level
- Incomplete coverage: The tool may not catch all risky operations depending on how it's configured
- Agent behavior hiding: A compromised or manipulated agent prompt could still attempt harmful actions within allowed limits
- Dependency vulnerabilities: Security depends on all underlying libraries staying patched
- Configuration mistakes: Wrong settings could leave dangerous capabilities exposed
How to lower the risk
Least-privilege permissions
- Grant agents only the specific permissions they actually need
- Regularly review and remove unnecessary access
Network isolation
- Restrict agents from reaching unnecessary services or external URLs
- Use firewall rules to block unexpected outbound connections
Monitoring
- Log all agent actions and review logs regularly
- Set up alerts for suspicious behavior patterns
Red flags to watch for
- Agents requesting more permissions than their task requires
- Unexpected network traffic or file access attempts
- Errors or timeouts that might indicate attempted escape
