Palo Alto Networks Launches AI-Driven Unit 42 Defense Service

Palo Alto Networks launched Unit 42 Continuous Frontier AI Defense, a global cybersecurity service designed to identify security vulnerabilities across corporate systems. The initiative responds to the increasing use of artificial intelligence by hackers to exploit network weaknesses.

The service utilizes a combination of open-weight models and advanced AI, specifically Anthropic's Claude Mythos 5 and OpenAI's GPT-5.6-Cyber. These models continuously test cloud infrastructure, application programming interfaces, and web applications to find gaps in security.

Customers receive guidance on resolving these vulnerabilities through code-level fixes and virtual patching. The service is available via annual subscriptions, with pricing based on the specific mix of AI models a business selects.
