100-word summary
OpenAI just dropped Lockdown Mode and Elevated Risk labels in ChatGPT—an optional security upgrade for executives, security teams, and other high-risk users handling sensitive enterprise data. The feature uses a deterministic approach to prevent data leaks by restricting external system interactions. Web browsing gets limited to cached content, while image responses, Deep Research, Agent Mode, Canvas networking, and file downloads are completely disabled. Currently available for ChatGPT Enterprise, Education, Healthcare, and Teachers plans, it'll expand to consumer and team plans soon. This signals OpenAI's push into enterprise-grade security as AI tools handle increasingly sensitive corporate information.
