AegisAI deploys autonomous AI agents that detect and neutralize phishing, malware, and business email compromise before they reach the inbox. Instead of a single machine learning model or a static rulebook, AegisAI runs a network of specialized agents that reason together like a team of security analysts: scanning attachments, following QR codes, analyzing sender behavior, and building context around every message in real time. It works like having an email security analyst in front of every single inbox. AI-generated phishing achieves a 54% click-through rate versus 12% for human-written attacks, and attackers can now build a sophisticated campaign in 5 minutes, a task that used to take experts 16 hours. Legacy secure email gateways and rule-based systems rely on blocklists, signature matching, and reputation scoring, all of which AI-generated attacks systematically defeat. AegisAI's agents analyze behavior, intent, and context instead, finding 22% more attacks than incumbent tools in production while cutting false positives by up to 90%. AegisAI connects to Microsoft 365 and Google Workspace via API and deploys in about 5 minutes, with no mail flow changes, no MX record updates, and no months of rule tuning. Every verdict comes with the agent's reasoning fully visible, so security teams can see exactly why a message was quarantined instead of trusting a black box. AegisAI was founded by Cy Khormaee and Ryan Luo, who spent a decade at Google on Safe Browsing and reCAPTCHA protecting billions of users. The company has raised $49M, most recently a $36M Series A led by Battery Ventures with participation from Accel and Foundation Capital.
