About Lumeus

Lumeus is a cybersecurity company specializing in AI Security, founded in 2021 and headquartered in San Jose, United States. It has raised $6M in total funding, employs about 5 people, and was acquired by Fiddler AI in 2026.
Lumeus is a cybersecurity company focused on securing AI agents and developer workflows. The platform provides discovery, posture management, and runtime protection specifically designed for AI agent environments, including IDE plugins, CLI integrations, and Model Context Protocol (MCP) workflows. The platform deploys as a native plugin for code editors such as VS Code, Cursor, and Windsurf, enabling inline protection and governance directly within developer coding environments. It also integrates via CLI to provide policy-governed access to AI tools and enforces access control on AI-to-server sessions with full auditability. Key capabilities include the discovery and classification of sanctioned and unsanctioned AI agent activity, integration with IAM, SIEM, and third-party platforms for security orchestration, and enforcement of enterprise policies and threat detections at the agent edge. The platform supports context-driven, just-in-time access approval or revocation and streams end-to-end audit logs across agent and developer workflows. A core aspect of Lumeus's approach is the elimination of long-lived credentials such as Kubernetes configs, SSH keys, and API tokens. Instead, it issues ephemeral, zero-standing credentials scoped to individual sessions, reducing persistent credential risk. The platform also supports multi-agent governance, providing unified discovery, policy enforcement, and visibility across all agents from a central interface, contrasting with per-agent, siloed security approaches.
