Palo Alto Networks to Acquire Koi in Reported $400 Million Transaction

"Koi, which raised $48 million in funding, offers an endpoint security platform that focuses on protecting various types of software, including applications, code, operating system packages, extensions, AI models, AI agents, and containers. The platform includes tools for automatic discovery and inventory of software across IT setups. It employs an AI-driven risk engine to analyze factors like code changes, runtime actions, update paths, and network outflows for real-time threat detection."

""AI agents and tools are the ultimate insiders. They have full access to your systems and data, but operate entirely outside the view of traditional security controls," said Lee Klarich, chief product and technology officer at Palo Alto Networks. "By acquiring Koi, we will be closing this gap and setting a new standard for endpoint security. We will give our customers the visibility and control required to safely harness the power of AI-ensuring that every agent, plugin, and script is governed, verified, and secure.""

Palo Alto Networks has entered a definitive agreement to acquire endpoint security company Koi, with Israeli reports valuing the deal at $400 million. Koi’s platform protects applications, code, operating system packages, extensions, AI models, AI agents, and containers. The platform provides automatic discovery and inventory across IT environments and uses an AI-driven risk engine to analyze code changes, runtime actions, update paths, and network outflows for real-time threat detection. Remediation capabilities include quarantining risky elements, reverting versions, and notifying owners. A supply chain gateway curates incoming software from sources like GitHub and Hugging Face. Palo Alto aims to integrate Koi into Prisma AIRS and Cortex XDR to improve visibility into the AI attack surface.
