Hush Security has raised $30 million in Series A funding as the company expands its identity-security platform to cover AI agents, an emerging area of enterprise risk as companies increasingly allow autonomous software to act inside sensitive systems.
Akamai Technologies joined the round as a strategic investor, alongside existing backers Battery Ventures and YL Ventures. The new financing brings Hush’s total funding to $41 million, less than a year after the company emerged from stealth.

Hush focuses on securing non-human identities, a category that includes secrets, service accounts, machine identities and now AI agents. The company says its platform gives enterprises a way to register AI agents, remove standing credentials and grant scoped just-in-time permissions when agents act across corporate systems. It also logs agent activity and allows organizations to revoke access from a central control point.
The company is positioning the product as a response to a governance gap created by the rapid adoption of AI agents. Citing Gartner, Hush said the average Fortune 500 company is expected to run more than 150,000 AI agents by 2028, compared with fewer than 15 last year. It also cited Omdia research indicating that 96% of organizations are using governance models for AI agents that were not designed for them.
AI agents are increasingly being deployed to perform tasks across enterprise applications, cloud environments and internal systems. That autonomy has created concern among security teams because agents may rely on broad or persistent credentials, making it harder to attribute actions, limit permissions or shut down activity when something goes wrong.
“Every company already knows how to manage identity for its people and its applications,” said Micha Rave, Hush Security’s CEO and co-founder. “But now software acts autonomously, on its own initiative, inside your most sensitive systems. AI agents need strict identity, not just API keys. We solved that for non-human identities, and now we’re extending governance to AI agents.”
The company said its expanded platform is designed to help organizations discover AI agents across managed and shadow environments, cloud systems, endpoints and AI platforms; control their permissions through a centralized registry; and audit their actions for investigations, governance and compliance.
Investors said the company is benefiting from two converging trends: the long-standing challenge of securing machine identities and the newer risks created by AI agents acting with real authority inside corporate environments.
Hush said it will use the funding to grow its engineering and sales teams, particularly in the United States, expand support for enterprise identity and access management systems and AI agent ecosystems, deepen integrations with enterprise AI platforms and build additional corporate partnerships.
The company was founded by the team behind Meta Networks, which was acquired by Proofpoint in 2019.
