Autonomous AI agents and proprietary LLMs that defend enterprise email
About AegisAI Security
AegisAI is a San Francisco cybersecurity company that builds proprietary large language models and autonomous agents to defend enterprise inboxes against AI-generated spear phishing, business email compromise and evasive payloads that pass traditional filters. Founded in 2025 by former Google security leaders Cy Khormaee (CEO; reCAPTCHA/Safe Browsing/Web Risk) and Ryan Luo (CTO), the platform integrates with Microsoft 365 and Google Workspace via API and extends beyond the inbox with Vanguard, an agent that follows suspicious links and attachments across the open web. Customers named in company materials include Mesh, LangChain and Lokker. After a $13 million seed co-led by Accel and Foundation Capital (Sep 2025), AegisAI raised $36 million in Series A funding led by Battery Ventures in July 2026, with Accel and Foundation Capital participating, bringing total funding to $49 million to scale defense agents and enterprise go-to-market.
