AnterisLab is a real-time policy engine for autonomous agents. It functions as a guard layer that sits between an agent and the external systems it accesses, such as payment gateways, email services, and databases. The tool intercepts every action an agent attempts and evaluates it against defined policies before the action is allowed to execute. This provides a zero-trust safety mechanism for agent operations. The system operates through a defined pipeline. It captures every tool call or action before it reaches its target. Each action is simulated, enriched with contextual data, and scored against policies written in plain language. Based on the scoring, the action is approved, paused for human review, or blocked. The warm path decision latency is under 15 milliseconds. Every decision generates a millisecond-level audit trail that is exportable and designed for compliance purposes. AnterisLab integrates with existing agent frameworks and platforms. It offers multiple service tiers. The free tier includes 500 decisions per month and community support. The Pro tier supports up to 5 agents and 10,000 decisions per month, with a 90-day audit trail and custom policies. The Enterprise tier provides unlimited agents, dedicated infrastructure, and compliance features including SOC 2 Type I, HIPAA BAA, and SSO. The tool is designed for developers and organizations that need to enforce safety, compliance, and cost controls on autonomous agent actions.
