Unit 42 launches Continuous Frontier AI Defense as an always-on service

On September 22, 2026 Palo Alto Networks' Unit 42 launched Continuous Frontier AI Defense, an always-on service that pairs offensive security experts with multi-model AI testing. It runs a full-estate baseline scan and then keeps testing as environments change, and it is sold worldwide on an annual subscription. Pricing was not disclosed, so the revenue impact is not yet measurable.

• Sold worldwide on an annual subscription; pricing not disclosed
• Uses Anthropic's Claude Mythos 5 and OpenAI's GPT-5.6-Cyber, plus open-weight models
• Built on the Frontier AI Defense offering launched in April 2026
