Oso for Agents is a platform for organizations to discover, monitor, detect, and control AI agent activity inside their company. It addresses the problem that AI coding agents, browser agents, and other autonomous tools often run with broad inherited permissions and no visibility or audit trail. Oso for Agents lets security and IT teams see every agent running across endpoints, browsers, and network traffic; monitor every prompt, tool call, and response; get alerted on policy violations or sensitive data exposure; and enforce rules on what agents can and can't do. ###What problem does Oso for Agents solve? AI agents inherit human-scale permissions and act on them at machine speed, creating security risk that traditional access controls weren't built to handle. Oso provides the visibility and enforcement layer that fills this gap. ###What is Shadow AI, and how does Oso address it? Shadow AI refers to AI agents and tools that employees are using without IT or security teams knowing about them — installed on laptops, running in browsers, or making network calls outside sanctioned channels. Oso for Agents continuously inventories agent activity across all these surfaces so organizations can identify unsanctioned tools and shut them down or bring them under policy. ###What does Oso monitor in an AI agent session? For approved agents routed through Oso's edge proxy, Oso captures every prompt sent to the model, every completion returned, every tool call made, and the data that flows through the session. This produces a full, step-by-step timeline of what the agent did — useful for incident investigation, compliance, and audit. ###What kinds of alerts does Oso generate for agents? Oso generates alerts for: detection of unsanctioned agents, PII appearing in agent sessions, API keys surfacing in prompts or completions, high-velocity unusual behavior, violations of custom policies (e.g., "block unknown MCP servers," "deny all delete operations," "allow only ChatGPT and Claude"). ###Why can't you just prompt-engineer your way to safe agents? Prompt-based safety isn’t enough. Prompting an agent to "only do safe things" is not deterministic and therefore not a reliable control. Oso enforces policy deterministically, so what agents can access and do is constrained by actual authorization rules, not instructions the model may ignore or be tricked into bypassing. ###What is Oso for Apps? Oso for Apps is a managed authorization service that lets engineering teams externalize and centralize their permissions logic rather than hand-coding it throughout their codebase. It answers questions like "can this user read that document?" or "which objects can this user manage?" It supports RBAC (Role-Based Access Control), ReBAC (Relationship-Based Access Control), and ABAC (Attribute-Based Access Control). Teams use it to ship roles, fine-grained permissions, and sharing logic without rebuilding from scratch. We built upon our expertise in permissions for applications to build Oso for Agents. ###Who uses Oso? Oso is trusted by organizations including Duolingo, Vanta, and Brex.
