Nikesh Arora, CEO of Palo Alto Networks, stated on Tuesday that nearly $1 trillion worth of existing cybersecurity infrastructure is not equipped to handle the demands of artificial intelligence (AI). Speaking to CNBC, Arora highlighted that much of the current security technology was designed seven to ten years ago, before AI became a central factor in cybersecurity threats and defenses.
Arora explained that the rapid advancement of AI is forcing companies to modernize their cybersecurity frameworks to keep pace with evolving threats. He emphasized that legacy systems, which dominate the cybersecurity landscape, lack the capabilities to effectively manage AI-driven attacks or leverage AI for defense. This gap is creating urgency among enterprises to invest in new security technologies tailored for AI environments.
The significance of this statement lies in the scale and impact of the cybersecurity market, which Arora pegged at about $1 trillion globally. As AI adoption accelerates across industries, the vulnerability of outdated security infrastructure could lead to increased risks of breaches and data loss. Palo Alto Networks, a major player in cybersecurity, is positioned to benefit from this transition as organizations seek advanced AI-compatible solutions.
Palo Alto Networks’ CEO made these remarks on September 1, 2026, during a CNBC interview, underscoring the immediate need for cybersecurity modernization. The company’s next quarterly earnings report, scheduled for October 15, will provide insights into how these market dynamics are influencing its business performance.
