readability=\"28.355817875211\"><body readability=\"57.908629441624\"><\/p>\n<p>Palo Alto Networks announced Tuesday its plans to buy security startup Koi, a deal aimed at addressing the security risks emerging as organizations rapidly adopt agentic AI.<\/p>\n<p>Terms were not disclosed, but Israeli business outlet <a href=\"https:\/\/en.globes.co.il\/en\/article-palo-alto-networks-to-buy-israeli-co-koi-security-1001535257\">Globes<\/a> reported that Palo Alto will pay approximately $400 million. The deal is another among a trend of larger <a href=\"https:\/\/cyberscoop.com\/proofpoint-acuvity-deal-agentic-ai-security\/\">cybersecurity industry companies buying<\/a> AI-focused security startups. <\/p>\n<p>In a statement announcing the agreement, <a href=\"https:\/\/cyberscoop.com\/tag\/palo-alto-networks\/\">Palo Alto Networks<\/a> argues that \u201cagentic\u201d tools are reshaping endpoint risk because they can act with broad privileges, interact with multiple systems and move data in ways that older security products were not designed to monitor. For years, endpoint protection emphasized detecting malicious files and stopping known malware techniques. The new concern described in the announcement centers on legitimate software that can become dangerous through compromise, misconfiguration or abuse. AI agents, in this framing, resemble highly capable insiders: they operate using a user\u2019s credentials, can take actions on a user\u2019s behalf and may do so automatically and at speed.<\/p>\n<p>\u201c<a href=\"https:\/\/cyberscoop.com\/tag\/agentic-ai\/\">AI agents<\/a> and tools are the ultimate insiders,\u201d said Lee Klarich, Palo Alto\u2019s chief product & technology officer. \u201cThey 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 <a href=\"https:\/\/cyberscoop.com\/tag\/artificial-intelligence-ai\/\">AI<\/a> \u2014 ensuring that every agent, plugin, and script is governed, verified, and secure.\u201d<\/p>\n<div class=\"ad ad--inline_1 \">\n<div class=\"ad__inner\"> <span class=\"screen-reader-text\">Advertisement<\/span> <\/div>\n<\/div>\n<p>Palo Alto Networks says Koi\u2019s technology would be integrated into its Prisma AIRS AI security platform and would enhance the company\u2019s Cortex XDR endpoint product. The stated goal is better visibility into AI-driven activity on endpoints and additional controls over tools that fall outside conventional security monitoring.<\/p>\n<p>Palo Alto Networks and Koi describe their approach moving forward as \u201cAgentic Endpoint Security,\u201d built around visibility into AI-related software, continuous risk analysis and real-time policy enforcement. The language suggests an attempt to define a new product category at a moment when enterprises are still deciding how to govern AI tools that are proliferating through developer workflows and everyday office software.<\/p>\n<p>The proposed acquisition also signals how major security vendors may respond to enterprise AI adoption: by packaging agent governance, monitoring and control into endpoint and cloud security portfolios, and by treating AI-driven automation as a distinct source of risk rather than a feature layered onto existing defenses.<\/p>\n<p>The acquisition is the second AI-focused deal for Palo Alto in the plast six months. In November, the company announced <a href=\"https:\/\/cyberscoop.com\/palo-alto-networks-to-acquire-observability-firm-chronosphere-for-3-35-billion\/\">it was acquiring Chronosphere<\/a>, an AI-focused observability firm, for $3.35 billion. <\/p>\n<p><\/body> <\/p>\n<footer class=\"single-article__footer\" readability=\"3.812292358804\">\n<div class=\"author-card\" readability=\"14\">\n<div class=\"author-card__avatar\">\n<figure class=\"author-card__image-wrap\"> <img data-recalc-dims=\"1\" decoding=\"async\" class=\"author-card__image\" src=\"https:\/\/i0.wp.com\/ddi.mohflo.net\/wp-content\/uploads\/2026\/02\/palo-alto-networks-koi-acquisition-is-all-about-keeping-ai-agents-in-check-1.jpg?w=640&ssl=1\" alt=\"Greg Otto\"> <\/figure>\n<\/p><\/div>\n<p><h4 class=\"author-card__name\">Written by Greg Otto<\/h4>\n<p> Greg Otto is Editor-in-Chief of CyberScoop, overseeing all editorial content for the website.
