AI Summary— plain English for professionals
# OpenAI Limits Access to Its New Security Tool OpenAI is releasing a new tool designed to help find computer security weaknesses, but it's only giving access to professional cybersecurity experts at first—not the general public. The company is being cautious because such a tool could potentially be misused by hackers if it were widely available. This is similar to a recent decision by competitor Anthropic to restrict access to their own security testing tool.
OpenAI will begin rolling out it cybersecurity testing tool, GPT-5.5 Cyber only "to critical cyber defenders" at first.
