AegisAI offers an enterprise email security platform that protects against phishing, malware, and BEC. It uses a network of autonomous AI agents—custom LLMs—that cooperatively inspect links, attachments, metadata, and user behavior in real time, replacing static rules. It deploys via API integrations with Microsoft 365 and Google Workspace for rapid setup, targeting fintech and tech enterprises, and is led by former Google security leaders with an agent-based approach that reportedly reduces false positives by up to 90%. Its goal is to scale the platform across large organizations by accelerating product development and expanding go-to-market efforts.

AegisAI, an AI-native email security company backed by Accel and Foundation Capital, has released research showing AI-generated email attacks grew fivefold in 2025, now bypassing traditional security filters more than 50% of the time. The study analysed over 20,000 phishing, scam and malware emails, finding that AI-generated attacks are 75% more effective at evading traditional filters. In response, AegisAI is launching Project Vanguard, an autonomous defence AI agent that pursues threats hiding behind CAPTCHAs and cloaked pages. Built by the team behind Google's reCAPTCHA, Vanguard extends protection beyond the inbox by following suspicious links and attachments to their malicious destinations. The company, founded in 2025 by former Google security engineers, will demonstrate Vanguard at RSA Conference 2026, with early customer testing beginning later this year.
Former Google security engineers who built widely-used web protection tools have raised $13 million in seed funding for AegisAI, a startup targeting enterprise email security with autonomous artificial intelligence agents.
