HiddenLayer, an Austin, Texas-based cybersecurity startup born out of a cyberattack that exploited machine learning code at the founders’ prior company, has announced a $50 million Series A funding round today to further harden the defenses of the rapidly growing number of AI models being adopted by enterprises.

The round was led by M12 and Moore Strategic Ventures, with participation from Booz Allen Ventures, IBM, Capital One, and TenEleven.

“AI’s unapparelled rate of adoption fuels us to move even faster in achieving our mission to give every security professional the right tools and expertise for embracing AI securely,” said Chris Sestito, CEO and Co-Founder at HiddenLayer, in a statement in the company’s press release announcing the round.

Already, HiddenLayer helps safeguard AI/ML models used by a number of Fortune 100 firms across sectors inclucing finance, government and defense, and cybersecurity.
