Teach your agents when to say no.
nolabs draws enforceable boundaries around every AI agent at runtime. The autonomy you can't fully predict becomes autonomy you can trust — because it knows where to stop.

can co-exist
Useful agents say yes to almost anything. Safe agents know when the answer is no. That judgement can't be a guardrail bolted around the model — it has to live at runtime, the moment an action is attempted.
Define boundaries
Declare exactly what each agent is allowed to touch — files, networks, secrets, tools — as composable policy that scales across your agent fleet.
Control actions
Every tool call and side effect passes through a mediator. Allow, deny, or escalate for approval the moment an action is attempted.
Protect yet empower
Agents need real authority — access to secrets, passwords, and tokens. nono grants it while making exfiltration impossible.
Build trust
A tamper-evident black-box recorder of every agent action is captured. Ship audit-ready evidence that your autonomous systems stayed inside the lines.
Meet nono
nono is the leading open-source runtime that enforces agent boundaries. Isolate any agent or framework, write composable policy as code, and every tool call / action is checked before it happens — locally, in CI, or in production.
- Framework-agnostic — works with any agent or MCP tool
- Policy as code, versioned alongside your repo
- Sub-millisecond enforcement, zero model calls

GITHUB_TOKEN: trueThe enterprise layer for agent fleets
Everything in nono, operationalized for production at scale. We're building the nolabs platform with a small group of design partners — turning runtime boundaries into a system of record for security, platform, and compliance teams. Here's the layer taking shape.
Fleet-wide policy
Author, distribute, and version boundaries across thousands of agents from one control plane.
Live observability
Every decision, every agent, in real time. Trace any action back to the policy that allowed it.
Approvals & Guardrails
Route sensitive actions for human vetting with nolabs advanced agent threat analysis.
Compliance evidence
Tamper-evident audit logs designed to map to SOC 2 and ISO 27001 controls.
Identity & access
SSO, SCIM, and fine-grained roles so the right agents own the right boundaries.
Hosted Agents
Spawn coding agents in milliseconds, sandboxed from the first instruction.
Built by people who made software safer
At nolabs, we obsess over agent security — made for the future and built from the ground up. We have decades of experience building large distributed security platforms used by teams at Google, NVIDIA, OpenAI, and more.
That history is why we believe we're uniquely qualified to figure out how to let AI agents run safely in a new world. Agents are software that acts on its own. Securing them demands the same rigor we brought to the software supply chain, to identity, and to the systems the internet runs on.
We're building the runtime that lets autonomy be trusted by default — not hoped for.
