Cybersecurity Funding AegisAI Raises $36 Million for AI-Powered Email Security The company has raised a total of $49 million in funding, including from Battery Ventures, Accel and Foundation Capital. By SecurityWeek News | July 24, 2026 (8:01 AM ET) Flipboard Reddit Whatsapp Whatsapp Email Email security company AegisAI announced on Thursday that it has raised $36 million in a Series A funding round. The round was led by Battery Ventures, with participation from Accel and Foundation Capital. The new capital brings AegisAI’s total funding to $49 million, and the company says it will put the money toward expanding its lineup of autonomous detection agents, pushing its Vanguard agent toward general availability, and growing its enterprise go-to-market efforts. AegisAI was founded in 2025 by Cy Khormaee and Ryan Luo, who previously worked on Google’s security team and helped build reCAPTCHA, Safe Browsing and Web Risk. The company emerged from stealth in September 2025. The startup’s platform is built around a network of AI agents that review incoming email for signs of phishing, business email compromise and other threats. Rather than relying on static rules or known-bad signatures, the system is designed to evaluate the intent and identity behind a message. The product connects to Microsoft 365 and Google Workspace through an API, which the company says requires no changes to a customer’s MX records. In March, AegisAI introduced Vanguard, a companion agent that investigates suspicious links and attachments by navigating to them the way a human recipient would, then compiles a threat report within minutes. AegisAI frames its work around what it calls AI spear phishing: attacks that use language models to research a target, map their professional relationships and produce a personalized lure at a fraction of the cost such an effort once required.

It’s an AI model manipulating someone in your organization into handing over the keys, often through the most trusted, most vulnerable contact of the person it’s targeting,” said Khormaee, who serves as AegisAI’s CEO. “You cannot patch human trust. If your security program still relies on template-based phishing tests and awareness training, you are training your people to spot last year’s threat, not a capable agent crafting a novel lure just for them. When the attack is AI, the defense has to be AI,” Khormaee added.
