Argus by Sotero
Every agent action, verified before it runs
Zero-trust credentialing and policy enforcement for multi-agent AI systems
Trusted by the most innovative companies in the world
The problem
Agents are already acting. The controls haven’t caught up.
Agents act before anyone reviews
Autonomous systems take actions in seconds. By the time a human looks at what happened, the action has already reached production data.
Delegation chains nobody tracks
One agent calls another, which calls a third. Without a recorded chain, there's no way to answer who actually authorised the action at the end of it.
No standing record of what happened
Scattered logs aren't an audit trail. When a regulator or an incident review asks what an agent did and why it was allowed, the answer has to already exist.
The platform
Four pillars, one unified control plane
Identity, governance, enforcement, and auditing work as a single system. Each pillar feeds the others, which is how Argus catches the problems no isolated check can see on its own.
Identity
Agent Registry
A central directory of every agent allowed to act — its lifecycle state, the tools it may reach for, who it can delegate to, and which version is running. Identity you can point to, not infer.
Governance
Annotated Data Catalog
Metadata-rich catalogs that define what agents can access based on sensitivity and trust scores. Governance is written against the data itself, so access decisions stay correct as the estate changes.
Enforcement
Real-Time Credentialing
Ephemeral, context-aware credentials issued per action and expiring on their own. No standing privileges to inherit, borrow, or leave behind — zero-trust enforcement at the moment of the call.
Analytics
Behavioral Auditing
Consumes signals from the other three pillars to catch what no single check sees on its own — privilege creep, token replay, quiet exfiltration — and scores risk in real time.
Policy as Code
Policies are authored, versioned, and reviewed like any other code — every change tracked, every version rollable back, with an example library to start from.
Learn MoreEphemeral Credentials
Credentials are minted per request, scoped to the specific resources and operation, and expire in minutes. Nothing long-lived to steal or over-share.
Learn MoreImmutable Audit Trail
An append-only record of every policy decision and agent action, with the reason and matched rule attached — built for compliance review, not just debugging.
