OpenAI supplied European companies with the AI model GPT‑5.5‑Cyber to protect them from cyberattacks

OpenAI provides European companies with access to new AI models for cyber defense

*OpenAI has opened access to its latest models, including the specialized GPT‑5.5‑Cyber, to companies in Europe that are engaged in vulnerability hunting in corporate systems.*

Program participants
- Deutsche Telekom and Scalable Capital (Germany)

- BBVA and Telefonica (Spain)

- Sophos (United Kingdom)

These organizations received access through the *Trusted Access for Cyber* program.

What the program offers
* Trusted Access for Cyber is designed for companies in key sectors: finance, telecommunications, energy, and public services.

* Access to OpenAI models is limited only to cyber‑defense tasks – vulnerability detection, development of protective measures, and rapid threat response.

Emmanuel Mari (EMEA Director) emphasized the need for a balance between accessibility, usefulness, and safety:

> “We must block dangerous activity while still giving vetted specialists tools that truly help protect systems.”

Why it matters
Last month Anthropic launched the *Mythos* model, which significantly increased risks for banks and other organizations. The ability of modern AI models to write complex code opens new possibilities both for discovering vulnerabilities and exploiting them, raising concerns about destabilizing financial institutions.

European Commission’s reaction
OpenAI suggested Brussels open access to cybersecurity features. In response, Anthropic has not yet shown a similar willingness.

Former UK Finance Minister George Osborne, leading the *OpenAI for Countries* initiative, in a letter to the European Commission emphasized that democratizing cyber‑defense tools will strengthen collective security and align with European priorities.

New steps by OpenAI
* A new company was created with initial investments of over $4 billion to support organizations in developing and deploying AI systems.

* To accelerate scaling, OpenAI acquired consulting firm Tomoro.

Thus, OpenAI is strengthening collaboration with European companies by providing them secure access to cutting‑edge models for defending against cyber threats while promoting openness and collective security.
