Palo Alto Networks Acquires Two Israeli Cybersecurity Startups
Palo Alto Networks has acquired two Israeli cybersecurity firms in a matter of days. The company purchased one-year-old endpoint security startup Koi Security for $400 million and another unnamed firm for an estimated $300 million. The acquisitions signal a strategic effort to set the standard for next-generation endpoint defense against AI-driven threats.
- This continues a long-standing strategy for Palo Alto Networks, which has now acquired 12 Israeli companies since 2014, representing half of its 24 major global acquisitions during that period. Previous Israeli acquisitions include Cider Security for $300 million in 2022 and Talon Cyber Security for $625 million in 2023. - Koi Security was founded in 2024 by alumni of the Israeli Defense Forces' elite 8200 intelligence unit and had raised $48 million in venture capital before the acquisition. The founders previously demonstrated a major security vulnerability by creating a fake extension in the VSCode Marketplace that infected over 300 organizations in one week, including a major EDR developer. - The acquisitions are a direct response to the expanding attack surface created by AI. CEO Nikesh Arora stated that traditional security tools are often "blind to the new AI layer of software," including autonomous AI agents, browser plug-ins, and ephemeral code that operate on endpoints. - Koi Security's technology is designed to act as a gatekeeper for the software supply chain at the endpoint. It uses AI agents and large language models to scan and verify the integrity of applications, extensions, and AI models before they can be installed. - The new technology will be integrated into Palo Alto Networks' existing platforms, including its Cortex XDR endpoint solution and the Prisma AIRS AI security platform. This move aims to give security teams visibility into AI-driven activities on local devices, which Arora has identified as a significant, unmanaged risk. - These purchases are part of a massive, multi-billion dollar acquisition spree to build a comprehensive AI security platform. This recently included the $25 billion acquisition of Israeli identity security firm CyberArk and the $3.35 billion purchase of observability platform Chronosphere. - The trend of acquiring Israeli AI security startups extends beyond Palo Alto Networks. Competitor Check Point also recently purchased three Israeli startups for over $150 million to enhance its own AI-driven threat protection capabilities.
