Palo Alto Networks Introduces Frontier AI Critical Defense Program

A collaboration of leading technology providers to protect critical infrastructure against the rapid rise of AI-discovered vulnerabilities

Palo Alto Networks announced the Frontier AI Critical Defense Program, a first-of-its-kind initiative to protect critical infrastructure from AI-driven exploits. Through the program, leaders across operational technology (OT), healthcare, commercial software and open-source communities coordinate with Palo Alto Networks to deploy proactive “virtual patches,” neutralizing vulnerabilities at the network-level before attackers can exploit them.

Palo Alto Networks recently used Frontier AI models to uncover more than 14,000 previously unknown vulnerabilities in open source software, underscoring how AI could enable threat actors to automate cyberattacks and shrink attack timelines. Yet, critical infrastructure operators, constrained by strict uptime and safety testing, cannot patch at AI speed. This mismatch creates a significant exposure gap, leaving essential systems vulnerable long before software fixes can be safely deployed.

True defense at AI speed requires joint action. This program builds on our existing collaborations with IBM and Red Hat (as part of Lightwell), Microsoft (as part of MAPP) and OT leaders like Siemens and the Idaho National Laboratory (as part of the OT Threat Research Lab).

Today, the collaboration is expanding to include Anthropic, OpenAI, OT leaders like Mitsubishi and Axis Communications, industry consortiums for sharing risk information like Analysis and Resilience Center for Systemic Risk and Health-ISAC, OT research organizations like the independent, non-profit Energy R&D Institute (EPRI) and OSS initiatives like Akrites (an initiative from the Linux Foundation).

Palo Alto Networks Frontier Virtual Patching puts these insights into action to deliver proactive protection for joint customers. By combining Frontier AI threat discovery with trusted vulnerability intelligence, it delivers rapid network-level patches while safeguarding sensitive vulnerability details from attackers.

Lee Klarich, Chief Product Officer, Palo Alto Networks
“In the age of Frontier AI, the traditional, reactive race to build and deploy software patches before adversaries exploit a flaw is a losing battle. Protecting critical infrastructure requires a structural shift from isolated patching to collective, proactive intelligence. Through initiatives like our Frontier AI Critical Defense Program, we can neutralize threats at the network layer before they are weaponized.”
