OpenAI's GPT-5.5-Cyber gives verified defenders faster vulnerability research
New specialized AI models target critical infrastructure protection with trusted access.
Deep Dive
OpenAI has expanded its Trusted Access for Cyber program with GPT-5.5 and GPT-5.5-Cyber, helping verified defenders accelerate vulnerability research and protect critical infrastructure.
Key Points
- GPT-5.5 and GPT-5.5-Cyber are restricted to verified cybersecurity defenders only.
- GPT-5.5-Cyber is fine-tuned on vulnerability databases, exploit patterns, and incident response data.
- Early testing shows accelerated vulnerability research and improved critical infrastructure protection workflows.
Why It Matters
Domain-specific, access-controlled AI can radically speed up cyber defense without empowering attackers.
