Hush Security Raises $30M to Secure Enterprise AI Agents

Hush Security, a Tel Aviv-based startup founded in 2024, raised $30 million in a Series A round led by Akamai Technologies with participation from Battery Ventures and YL Ventures. The company emerged from stealth in September 2025.

The funding will support expansion of Hush’s platform, which enrolls AI agents in a central registry, issues scoped just-in-time permissions at runtime instead of long-lived API keys, records each agent action for audit, and provides a centralized kill switch to disable or revoke an agent’s access.

Hush’s software is designed to discover agents across an environment and map the model control planes, tools and resources those agents use. From a single management panel, security teams can register agents, set and visualize permissions, enforce policy for each action, and retain logs for investigations and compliance reviews.

The company plans to hire across engineering and sales teams, broaden identity and access management integrations for agent systems, and expand corporate partnerships. With the new investment, Hush has raised $41 million in total.

Micha Rave, co-founder and CEO, described the company’s approach: ‘Every company already knows how to manage identity for its people and its applications. 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.’

Investors in the round included Akamai as a new backer, alongside Battery Ventures and YL Ventures. Hush positions its product for enterprises deploying autonomous software and agent workflows that require runtime controls and clearer accountability than traditional application credentials provide.
