Zenity Raises $125 Million for AI Agent Security
Agentic AI deployments create runtime authorization risks that prompt-level controls miss - a gap APS security and AI governance teams will increasingly face.
Key points
- Zenity raised $125 million Series C to secure AI agent runtime actions and delegated tool access in enterprises.
- The funding signals growing investor demand for agent-specific security controls beyond prompt filtering - relevant as APS agencies evaluate agentic AI deployments.
- Growth and adoption figures are company-reported and unaudited; no valuation or independent benchmarking was disclosed.
Implications for Australian agencies
- Monitor APS security and AI governance teams may want to monitor the emerging AI agent security vendor landscape as agentic deployments within Commonwealth environments become more common.
- Consider Agencies evaluating agentic AI tools could consider whether their risk assessments address runtime authorization and tool-use risks, not only prompt-level controls.

Zenity, an AI agent security company, raised $125 million in a Series C round led by Norwest, bringing total funding to $180 million. The company sells controls that intercept AI agent actions at runtime - evaluating authorization, execution context, and tool use - rather than treating prompt filtering as the full security boundary. Its platform covers commercial agentic environments including Microsoft Copilot, ChatGPT Enterprise, Gemini, and Claude. The round signals strong investor appetite for agent-specific security as enterprises deploy agents with delegated access to corporate systems, a risk profile directly relevant to Australian agencies evaluating similar tooling.
Implications for Australian agencies:
- [Monitor] APS security and AI governance teams may want to monitor the emerging AI agent security vendor landscape as agentic deployments within Commonwealth environments become more common.
- [Consider] Agencies evaluating agentic AI tools could consider whether their risk assessments address runtime authorization and tool-use risks, not only prompt-level controls.
