Palo Alto CEO says $1 trillion cybersecurity infrastructure isn't AI-ready
Palo Alto Networks CEO Nikesh Arora said that AI is forcing companies to modernize roughly $1 trillion of aging cybersecurity infrastructure that is not equipped to handle attacks at machine speed. Speaking to CNBC's Jim Cramer, Arora noted that nothing deployed 7-10 years ago can handle AI, and that companies must rethink their cyber architecture. The comments came after Palo Alto Networks beat fiscal fourth-quarter estimates and gave a strong outlook. Arora highlighted the emergence of Anthropic's Mythos model as a turning point that made companies take AI security threats seriously. He said Palo Alto has engaged with about 2,000 companies on its Frontier AI Critical Defense Program, which uses advanced AI to test defenses. Arora believes the AI threat extends the growth runway for the entire cybersecurity industry, though spending will not materialize all at once.
AI-driven modernization of cybersecurity is relevant to digital infrastructure but not directly to AdTech; it indicates a broader industry trend but lacks direct advertising implications.

Palo Alto Stocks Drop Amid AI Pressure, CEO Defends Cybersecurity
Palo Alto Networks warned that artificial intelligence is not poised to replace cybersecurity, CEO Nikesh Arora said on an earnings call, defending the sector amid a broader selloff in software stocks. Shares fell about 7% after the company reported fiscal second-quarter results that beat Wall Street estimates but issued third-quarter guidance below expectations. Arora said customers are integrating AI into security stacks and that many security products now include copilots. Palo Alto has been investing in AI and M&A: it launched a suite of agentic tools in Q4, closed a roughly $25 billion acquisition of identity-security firm CyberArk earlier this month, completed the purchase of AI observability platform Chronosphere in January, and announced a deal to buy Israeli startup Koi.
Palo Alto: AI-driven cyberattacks to become new norm
Palo Alto Networks tech chief Lee Klarich warned that AI-driven cyberattacks will likely become the "new norm" within a narrow three-to-five-month window, urging organizations to urgently strengthen software defenses. Klarich cited advanced models — including Anthropic’s Mythos and OpenAI’s GPT-5.5-Cyber — as making it easier for attackers to discover and exploit previously unknown vulnerabilities. Palo Alto said it will roll out initial defensive capabilities, including virtual patching, "very soon." The article notes Anthropic limited Mythos access to a select group of companies (including Palo Alto Networks, CrowdStrike, Amazon, Apple and JPMorgan) and that Google recently said it blocked an attempt to use AI in a mass-exploitation event. The piece was published May 13, 2026.
Palo Alto CEO Says AI Slowdown 'Unrealistic', Extinction Risk 'Extremely Small'
Palo Alto Networks CEO Nikesh Arora told CNBC's 'The Tech Download' podcast that calls to slow AI development are 'unrealistic' and that the threat of AI causing human extinction is 'extremely small'. He argued that not all companies will pace themselves and that frontier developers should be responsible for safety. Arora also expressed doubts about US-China coordination on AI safety, citing differing views among US politicians and executives. His comments contrast with Anthropic CEO Dario Amodei's call for a slowdown and align with Nvidia CEO Jensen Huang's stance. Arora's remarks add to the ongoing debate about AI regulation and safety.
