AegisAI Security

AegisAI is a cybersecurity startup providing an advanced email security platform that utilizes autonomous AI agents to protect against phishing, malware, and Business Email Compromise (BEC) attacks. The company was founded by former Google security leaders Cy Khormaee and Ryan Luo, who applied their experience from developing Google's Safe Browsing and reCAPTCHA systems to address the shortcomings of traditional, rule-based email defenses. Khormaee, the CEO, previously led Google's security team, while Luo, the CTO, also brings extensive experience from his time at the tech giant.

The company emerged from stealth in September 2025 with a $13 million seed funding round co-led by Accel and Foundation Capital. The platform is designed to counter the rising threat of sophisticated, AI-generated email attacks that can bypass conventional filters. Instead of static rules, AegisAI employs a network of specialized AI agents, which are custom-built large language models (LLMs). These agents work collaboratively to inspect, analyze, and neutralize email threats in real-time by evaluating message components like links, attachments, metadata, and behavioral patterns. This approach reportedly reduces false positives by up to 90% compared to traditional solutions.

AegisAI's business model is centered on providing its platform as a service to enterprise clients, with a focus on high-growth startups and companies in the fintech and technology sectors. The solution integrates with Microsoft 365 and Google Workspace via API, allowing for rapid deployment without major infrastructure changes. Early customers include crypto payment platform Mesh Connect and data privacy software provider Lokker. The company has offices in San Francisco and New York and is using its seed funding to accelerate product development and expand its engineering and go-to-market teams.
