Palo Alto Networks to Acquire CyberArk for $25B in Major Security Deal

In a blockbuster move that is poised to reshape the cybersecurity landscape, Palo Alto Networks has announced a definitive agreement to acquire identity security leader CyberArk in a cash-and-stock transaction valued at approximately $25 billion. This monumental deal, which marks Palo Alto Networks’ formal entry into the identity security market, is one of the largest in the history of the cybersecurity industry.

The acquisition is a strategic move for Palo Alto Networks, which aims to accelerate its “platformization” push and create a more complete security offering for its customers. By integrating CyberArk’s privileged access management and identity security solutions into its existing platform, Palo Alto Networks will now have a presence in nearly every major cybersecurity category, from network security to cloud and endpoint protection.

Palo Alto Networks Chairman and CEO Nikesh Arora stated that the acquisition is a response to the evolving threat landscape, particularly the rise of AI and the proliferation of both human and machine identities. “Our market entry strategy has always been to enter categories at their inflection point, and we believe that moment for Identity Security is now,” Arora said in a statement. “The rise of AI and the explosion of machine identities have made it clear that the future of security must be built on the vision that every identity requires the right level of privilege controls.”

CyberArk, a global leader in identity security, specializes in protecting privileged accounts and sensitive data from both external attackers and internal threats. The company’s solutions are considered foundational for a “Zero Trust” security model, which assumes that no user or device can be trusted by default, regardless of whether they are inside or outside the network.

The deal, which represents a significant premium for CyberArk shareholders, is expected to close in the second half of Palo Alto Networks’ fiscal 2026, subject to customary closing conditions and regulatory approvals. The acquisition is set to intensify the competition among cybersecurity giants, as companies like Palo Alto Networks, Google, and Cisco race to build all-in-one security platforms to address the complex and multifaceted nature of modern cyber threats.
