Build agents you can trust. We’ll keep them out of trouble.

Simulations, deterministic controls, and zero-config mitigations for agents that actually touch prod.

Trusted by

You focus on making agents useful. We make sure they don’t wreck your stack.

Simulate

Break your agents in staging, not prod

Spin up simulations that hit your real tools and data paths.

Watch agents try to exfiltrate, spam tools, or follow bad prompts—then patch the behavior before it ships.

Tight loop: run, watch, fix, repeat.

Detect

Catch weird behavior fast

Agents drift. Prompts change. Tools grow.

We watch real behavior over time and compare it to what’s normal for your org.

When something starts to look off, we kill its access, quarantine the agent, and roll back the changes.

Enforce

Least privilege, wired into every call

Every tool call goes through Oso.

We look at the intent, the user, and the context, then grant the minimum access needed to do the job.

High‑risk actions (deletes, payments, wide‑scope reads, the “Lethal Trifecta”) go through hard controls, not clever prompting.

Audit

Receipts

Full trails of who did what, through which agent, and with which permissions.

Views that show over‑permissioned agents, risky tools, and how your posture is trending.

So when the CEO asks, “Is this safe?”, you can show them.

You can’t prompt your way to least privilege. Oso wires it into every call. Let’s have a cocktail.

Agents should unlock creativity, not create new categories of risk. Oso's approach—simulate, enforce, detect—is exactly how you make that real.

We want partners who understand where security is headed, not just where it's been. Oso gets that agentic systems need fine-grained authorization baked in from the start.

Agents in production need the same rigor we bring to clinical decisions: precise, measurable, auditable. Oso gets that.

Oso made building Productboard Pulse much faster, since every API can just call Oso to figure out what’s allowed, no matter where the data resides. By building on top of a proven authorization foundation, we’ve avoided the biggest hurdles derailing AI efforts in many companies.
