AegisAI raises $36M to stop AI-powered spear phishing
Hackers' AI now bypasses legacy email defenses 50% of the time.
AegisAI, a startup founded by former Google security executives Cy Khormaee and Ryan Luo, has raised $36 million in Series A funding led by Battery Ventures to combat AI-driven spear phishing. The company uses proprietary AI agents that mimic human email analysis, catching subtle anomalies that rule-based systems miss. With a total of $49 million raised, AegisAI claims its tech can detect malicious PDFs, including those with passwords and CAPTCHA, that fool traditional filters. Customers include Mesh, LangChain, and Lokker.
Co-founder Khormaee notes that AI-powered attacks bypass existing controls more than half the time, making them nearly twice as effective. AegisAI competes with startups like Ocean and Abnormal Security, but investors believe the team's Gmail security experience gives them an edge. The startup plans to expand beyond email into data security, aiming to become the next dominant security company by deploying specialized agents for investigations.
- AegisAI's AI agents analyze email context to detect anomalies that rule-based systems miss, catching encrypted PDFs and CAPTCHA-laden attachments.
- The $36M Series A (Battery Ventures, Accel, Foundation Capital) follows adoption by crypto payments firm Mesh, AI startup LangChain, and privacy platform Lokker.
- Co-founder Khormaee reports AI-powered spear phishing now bypasses legacy defenses over 50% of the time, driving demand for agentic email security.
