Palo Alto Networks unveils AI-powered cybersecurity service using Claude, GPT models

The service uses cyber-specialized models to run always-on scans, with Palo Alto Networks saying customer tests found exposures in 100% of organizations.

  • On Tuesday, Palo Alto Networks launched Unit 42 Continuous Frontier AI Defense, an agentic offensive security service using gated AI models from Anthropic and OpenAI to perpetually find, validate, and remediate enterprise security exposures before attackers exploit them.
  • Threat actors are deploying AI to accelerate breach cycles by almost 97%, compressing attack timelines from weeks to hours. Palo Alto Networks invested $17 million over six months developing this service to enable defenders to match machine-speed attacks.
  • Internal tests uncovered a year's worth of exposures in three weeks, while customer assessments found security flaws in 100% of organizations tested. With 37% of those rated high or critical, the service uses a multi-model harness to route tasks to optimal AI models.
  • The service tests web apps, APIs, and cloud infrastructure as environments change, attempting to validate real-world attack paths. It provides actionable remediation including code-level fixes and virtual patching options to mitigate vulnerabilities before official patches exist.
  • Palo Alto Networks CEO Nikesh Arora said, "If you believe that half of what's going to happen or be possible with AI hasn't been invented yet, then half of that security is missing, too." This underscores evolving security demands.
