Milan-based cybersecurity startup Beelzebub has raised a €3 million seed round led by United Ventures, following a €300,000 pre-seed backed by strategic investors and advisors.

Founded in 2025, Beelzebub is building an AI-native cybersecurity platform designed to combine red team and blue team functions into a single autonomous defense loop. Its technology spans continuous adversary emulation, runtime deception, and autonomous threat intelligence, aiming to help organizations detect and respond to attacks at machine speed.

The company says the platform grew out of several years of open-source development and is already being used in customer deployments and pilot projects across large enterprises, critical infrastructure, and government environments. The new funding is expected to support the next stage of product development and growth.
