Hush Security raised $30 million in a Series A round, announced on August 20, 2026 and led by Akamai. The raise puts fresh capital behind a narrow but fast-growing problem: how enterprises govern AI agents that now have permission to touch real infrastructure.
Here's the full breakdown of the raise and what it means for the agent security market.
What is Hush Security?
Hush Security is an AI agent governance platform. It enrolls autonomous agents in a registry, manages just-in-time permissions, and controls what those agents can access as they spread across enterprise systems. Founded in 2025, the company emerged from stealth that September before raising this Series A less than a year later.
The raise: $30M Series A
The headline numbers:
- Amount: $30 million
- Round: Series A
- Announced: August 20, 2026
- Lead investor: Akamai
Hush Security emerged from stealth in September 2025 with an undisclosed seed round. This Series A brings its total funding to $41 million — a quick follow-on that suggests the company found demand for agent governance tooling faster than a typical enterprise security startup.
Who invested in Hush Security?
The Series A was led by Akamai. No co-leads or additional participants were disclosed for this round. Akamai's involvement is notable given its position as a major infrastructure and security vendor, rather than a traditional venture fund.
What Hush Security will do with the money
The company says the funding will go toward agent governance infrastructure, security framework development, and enterprise integrations — the work of making its registry and permissioning system plug into the identity and access systems large organizations already run.
Why it matters
Hush Security's raise reflects a security category that's forming quickly around AI agents:
- Agent sprawl is becoming a real security problem, not a hypothetical one. Gartner projects Fortune 500 firms will run more than 150,000 AI agents by 2028, up from fewer than 15 today — a scale of autonomous software identity that most enterprise security stacks were never built to track.
- Identity and access control is shifting from humans to software. As agents gain the ability to act on real infrastructure, the just-in-time permissioning model Hush Security is building addresses a gap that's distinct from traditional human identity management, similar in spirit to how other agent-focused startups are racing to define the operational layer around autonomous systems.
- A major infrastructure player leading the round is a signal of urgency. Akamai leading rather than co-investing suggests strategic interest from a company that already secures internet-scale infrastructure and sees agent governance as adjacent to its core business.
