AegisAI Raises $36 Million to Expand AI Email Security

AegisAI says it will use the new capital to expand its autonomous email-detection agents, grow its enterprise go-to-market operation, and move Vanguard toward general availability. Vanguard is designed to follow suspicious links and attachments beyond an email inbox and return an investigation report.

The company positions its platform as an AI-native alternative to rule- and signature-heavy email filtering. Its software connects to Google Workspace and Microsoft 365 through APIs and uses language models and coordinated agents to evaluate message intent, sender behavior, links, and other context.

AegisAI was founded in 2025 by Cy Khormaee and Ryan Luo, former members of Google's security organization who worked on products including reCAPTCHA, Safe Browsing, and Web Risk. The company emerged from stealth in September 2025 with a $13 million seed round.

SecurityWeek independently reported the Series A amount, participating investors, total funding, and stated expansion plans. The funding announcement itself was distributed by AegisAI through PR Newswire.

The release includes claims about detection quality, phishing trends, and reductions in false positives. Those figures come from the company and its own telemetry or customer accounts; the announcement does not provide a controlled, independent comparison across competing email-security products.

For security teams, the useful signals to watch are operational: general availability and pricing for Vanguard, documented deployment requirements, independently measured false-positive and missed-threat rates, and how the system handles permissions and sensitive message data. The funding gives AegisAI more resources to scale, but it does not by itself validate the product's comparative effectiveness.
