Palo Alto Networks launches AI-driven Unit 42 service using Claude and GPT models

Unit 42 Continuous Frontier AI Defense and its underlying models

Palo Alto Networks on Tuesday introduced Unit 42 Continuous Frontier AI Defense, a subscription service designed to continuously probe web applications, application programming interfaces and cloud infrastructure as customer environments change. The service runs on cyber-focused AI models including Anthropic's Claude Mythos 5 and OpenAI's GPT-5.6-Cyber, alongside open-weight models, and is intended to surface vulnerabilities and possible attack paths in near real time rather than at periodic scan intervals.

How the offering operates inside customer environments

According to Palo Alto Networks, the service is built to identify security gaps across corporate systems and to pair each finding with remediation guidance, including code-level fixes and virtual patching options. Reuters, citing the company, framed the launch as a direct response to hackers increasingly using AI to find and exploit weaknesses in corporate networks, with the goal of shortening the window between detection and response.

Pricing, availability and model mix

The company said the service will be available globally through annual subscriptions, with pricing tied to the combination of OpenAI, Anthropic and open-source models a customer selects. Palo Alto Networks did not disclose list prices or a launch date beyond Tuesday's announcement, leaving the deployment timeline and regional rollout details to be set by individual customer agreements.

Underlying motivation and competitive backdrop

The launch positions Palo Alto Networks against a wave of adversaries weaponizing generative AI for reconnaissance and intrusion, and pairs the company explicitly with two of the highest-profile model providers. Reuters also reported the news, indicating that the service was communicated through Palo Alto Networks' announcement to wire services as well as through technology press coverage, broadening the visibility of the Claude- and GPT-backed product to enterprise security buyers.
