    OpenAI has restricted access to its cybersecurity tool, Cyber. This tool will now only be available to critical cyber defenders who meet specific criteria.

    The company is implementing this restriction due to concerns about potential malicious use.

    The GPT-5.5 Cyber model is capable of performing complex operations such as penetration testing and vulnerability detection.

    Users wishing to access the tool must complete an application form detailing their credentials and intended use.

    This decision comes despite criticism faced by another company that previously implemented similar restrictions. OpenAI aims to ensure trusted access and make the tool available to a wider audience by collaborating with the U.

    S. government.

    These restrictions are expected to reduce the risks of unauthorized access in the cybersecurity domain. The company intends to enhance the security of cyber infrastructure through this strategy.
