Zenity raises $125M Series C backed by SoftBank, Hitachi, LG

Enterprises are deploying autonomous AI agents faster than they can audit them, turning agent oversight into cybersecurity's hottest new budget line.

• Zenity raised $125 million in a Series C round backed by SoftBank, Hitachi, and LG, according to Fortune.
• Zenity builds a security platform that gives enterprises full-lifecycle visibility, governance, and detection for AI agents from build time to runtime, across SaaS apps, custom software, and employee devices.
• The Series C follows more than $55 million raised previously, including a $38 million Series B backed by Microsoft's venture arm M12.
• Zenity's own research showed one employee clicking a malicious link let a rogue AI agent inherit every app the worker had already connected, no new approval required, then exfiltrate data and send phishing messages internally.
• AI-agent security is one of 2026's fastest-funded categories: Glow raised $180 million at a $1.2 billion valuation and Onyx Security raised $113 million at roughly $640 million, both within months of launching.
• As banks and enterprises chain dozens of AI agents together to automate core workflows like loan underwriting, oversight of what those agents can access has become a newly urgent, newly funded line item in security budgets.
