Zenity raises $125M Series C funding to expand AI agent security monitoring platform

Decision brief

What changed

Zenity, an Israeli AI security startup, raised $125 million in a Series C round led by Norwest with participation from SoftBank Vision Fund 2, Hitachi Ventures, and LG Technology Ventures, bringing its total funding to $185 million. The capital will fund expansion of its platform for monitoring and controlling autonomous AI agents in enterprise environments, including growth into Europe, Asia-Pacific, and the Middle East.

Why it matters

This signals growing investor and enterprise consensus that autonomous AI agents represent a distinct, urgent attack surface separate from model-level vulnerabilities, requiring dedicated runtime governance rather than traditional security tools. A related $85M raise by competitor Obsidian Security, citing that 65% of enterprise customers have already granted AI agents access to third-party SaaS data, suggests this is a live operational risk today, not a future concern. CISOs and CTOs evaluating AI agent deployments should treat agent-specific monitoring and access controls as a near-term procurement priority.

Evidence

The funding details (amount, lead investor, participants, total raised) are consistently reported across SiliconANGLE and Fortune, indicating solid confirmation of the deal terms. The broader market context—Obsidian Security's parallel raise and its stat on enterprise AI agent access—comes from a single SiliconANGLE article and has not been independently corroborated in this coverage set.

What remains uncertain

It is unclear how Zenity's specific technical approach differs from competitors like Obsidian Security, or how large its current customer base and revenue are, since no customer or usage metrics were disclosed for Zenity itself. The 65% enterprise adoption statistic comes from Obsidian's self-reported figures and lacks independent verification.

Monitor next

Watch for Zenity's customer and revenue disclosures or case studies as it expands into new regions, which would validate real enterprise demand versus investor speculation.
