Former Meta Networks founders raise $30 million Series A to secure the AI workforce
Hush Security, led by the team behind the Zero Trust startup acquired by Proofpoint, is building identity infrastructure for AI agents and other non-human identities.
Cybersecurity startup Hush Security has raised $30 million in a Series A round led by Akamai Technologies, as investors place new bets on a growing challenge created by the rise of autonomous artificial intelligence systems: how to control software agents that can act independently inside enterprise networks.
The round, which includes participation from existing investors Battery Ventures and YL Ventures, brings Hush’s total funding since its founding in 2024 to $41 million.
The investment comes as companies increasingly deploy AI agents capable of performing tasks without direct human involvement. According to Gartner, the average Fortune 500 company is expected to operate more than 150,000 AI agents by 2028, compared with fewer than 15 just last year.
But the security infrastructure needed to manage those agents has not kept pace. Recent research cited by Hush from Omdia found that 96% of organizations are running AI agents under governance models that were not designed for autonomous software.
Hush argues that identity, knowing what an agent is, what it is allowed to access, and what actions it performs, will become one of the central security challenges of the AI era.
“Every company already knows how to manage identity for its people and its applications,” said Micha Raveh, CEO and co-founder of Hush. “But now software acts autonomously, on its own initiative, inside your most sensitive systems. AI agents need strict identity, not just API keys.”
Hush was founded in 2024 by Raveh, CTO Shmulik Ladkani, VP R&D Alon Horowitz and Chief Customer Officer Chen Nisnkorn. The founders previously worked together at Meta Networks, which developed a Zero Trust platform and was acquired by Proofpoint in 2019 for $120 million.
Hush employs 31 people across Israel and the U.S.
The company initially focused on the broader challenge of securing non-human identities, accounts, services and machines that operate without a person directly controlling them. It is now extending that approach to AI agents, which Hush describes as a new category of non-human workers.
The company’s platform creates a central registry for AI agents and other machine identities, connects them to existing organizational permissions, and replaces permanent credentials with just-in-time access.
Instead of allowing an AI agent to hold long-term API keys or passwords, Hush gives it temporary permissions only when needed, while logging every action and allowing organizations to revoke access.
The platform is designed to help companies discover all AI agents operating across cloud environments, employee devices and AI platforms; control what those agents can access; and maintain audit trails for security and compliance.
Hush is already working with enterprise customers, including Kyndryl, the world’s largest IT infrastructure services provider. Kyndryl has deployed Hush internally and has begun offering the platform to its own customers.
