Palo Alto Networks launches Frontier AI Critical Defense Program

Palo Alto Networks has launched the Frontier AI Critical Defense Program, an initiative to protect critical infrastructure operators - including those in operational technology (OT), healthcare and open-source communities - from AI-driven exploits using proactive network-level virtual patches.

The company's Frontier Virtual Patching capability sits at the centre of the program, combining AI-driven threat discovery with vulnerability intelligence to deliver rapid network-layer patches without exposing sensitive vulnerability details to threat actors.

The approach is aimed at operators in sectors - such as energy, healthcare and industrial control - where strict uptime and safety requirements prevent rapid software patching.

The program builds on existing collaborations with IBM and Red Hat (through Lightwell), Microsoft (through the Microsoft Active Protections Program) and OT leaders including Siemens and Idaho National Laboratory (through the OT Threat Research Lab).

New participants joining the initiative include Anthropic, OpenAI, Mitsubishi, Axis Communications, the Analysis and Resilience Center for Systemic Risk, Health-ISAC, the Energy R&D Institute (EPRI) and Akrites, an open-source security initiative under the Linux Foundation.

"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," said Lee Klarich, chief product officer at Palo Alto Networks.

"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 neutralise threats at the network layer before they are weaponised."
