We're excited to co-lead @ArmadinSecurity's Series B. After this summer’s cyber incidents at frontier AI labs, CISOs face growing pressure to secure their companies across applications, cloud, identity, and internal networks. Armadin’s AI autonomous security platform turns offense into something defenders control, from the first Hyperattack. Built on decades of frontline adversary tradecraft, its agentic attacker swarm reasons, plans, and adapts like a real adversary. The platform learns from every attack and environment, allowing security teams to focus on fixing real problems. We believe there’s no better team to take this on than Kevin Mandia, Travis Lanham, Evan Peña, and David Slater. Kevin founded Mandiant, the firm that defined modern incident response. Kevin and the team have spent their careers staying a step ahead of attackers, and now they’re building the platform to help every security team do the same. @a16z @steph_zhang
