Arcjet Launches Runtime Security Product for Production AI Agents
San Francisco – – September 19, 2026 -- Arcjet has launched agent runtime security, a new product designed to give engineering and security teams visibility and control over AI agents operating inside production systems. The platform targets agents that read and write to databases, process refunds, call APIs, and take autonomous actions across multiple systems on behalf of users.
Arcjet builds its product around three functions: observe, enforce, and audit
The observe layer lets teams ingest agent activity without changing application code, using existing OpenTelemetry tooling or, for Claude users, the Claude Compliance API. Arcjet connects actions across sessions into a single workflow view, capturing prompts, tool call parameters, session metadata, identity, and security decisions, and maintains an inventory of agents and applications running in a given environment.
