Reported by Silicon Angle. Cybersecurity startup Armadin Inc. has announced a significant funding round, raising $255.5 million in Series B financing at a valuation exceeding $2.5 billion. The funding was co-led by Andreessen Horowitz and Accel, with participation from other notable investors including Alphabet Inc.’s GV startup fund.

Armadin, founded by cybersecurity veteran Kevin Mandia, offers a platform that deploys swarms of artificial intelligence agents to identify vulnerabilities within a company's infrastructure. These AI agents operate in a secure sandbox, preventing harmful activities while actively searching for weaknesses. The platform can generate tens of thousands of agents to map internal systems, scan assets, and identify potential attack paths. In one customer project, 26,000 agents scanned over 25,000 assets, uncovering 38 verified attack paths. Armadin's approach aims to counter the increasing speed and sophistication of AI-driven cyberattacks by allowing defenders to train against a simulated, advanced offense. The company plans to use the new capital to enhance its research, AI training, and go-to-market strategies.
