Palo Alto Networks announced it has entered into a definitive agreement to acquire Koi, a company focused on Agentic Endpoint Security, in a move designed to address what it describes as a growing AI-driven security gap across enterprise endpoints.
The company said that as artificial intelligence transforms workforce productivity, AI agents and tools are creating a new, unmanaged attack surface on endpoints. These “agentic endpoints” operate with broad access to sensitive data, permissions and automated capabilities, often outside the visibility of traditional security controls.
Palo Alto Networks characterized Agentic Endpoint Security as a new category of protection required to address this evolving risk. Modern AI agents can read, write and move data, while attackers are increasingly chaining exploits in agent frameworks, including authentication bypass and API-based remote code execution. The endpoint attack surface has expanded beyond traditional executables to include extensions, plugins, packages, scripts and model artifacts.
Following the close of the transaction, Koi’s Agentic Endpoint Security technology is expected to integrate with Palo Alto Networks’ Prisma AIRS platform, expanding protection across AI-driven operations. The company also plans to enhance its Cortex XDR endpoint security solution with deeper visibility into AI-related attack surfaces to strengthen security policy enforcement and malware prevention.
Palo Alto Networks said the acquisition will enable enterprises to deploy AI agents, plugins and scripts with greater visibility and governance. Additional details are expected to be shared during the company’s Q2 FY2026 earnings call.
Palo Alto Networks, traded on NASDAQ under the ticker PANW, provides cybersecurity solutions across network, cloud, security operations, AI and identity. The company reports serving more than 70,000 customers globally.
KEY QUOTES
“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. 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.”
Lee Klarich, Chief Product & Technology Officer, Palo Alto Networks
“We founded Koi to secure the next frontier of risk. In an agentic-first world, traditional solutions are blind. Joining forces with Palo Alto Networks will allow us to scale our technology to the world’s largest organizations, delivering protection that makes work on the modern AI-native endpoint secure by design.”
Amit Assaraf, CEO And Co-Founder, Koi
