OpenAI has launched a new “Lockdown Mode” for ChatGPT aimed at enhancing user privacy and protecting sensitive information from emerging AI security threats, particularly prompt injection attacks. The feature is designed for individuals and organizations handling confidential data, offering an additional layer of security against potential data leaks. According to the company, prompt injection attacks involve hidden instructions embedded in websites, emails, or documents that can mislead AI systems into revealing sensitive user information. While the Lockdown Mode does not completely eliminate such risks, it significantly reduces the possibility of data exfiltration by limiting how ChatGPT interacts with external inputs and services.
When enabled, the mode restricts several advanced capabilities of ChatGPT. Live web browsing is limited to cached content, while features like Deep Research and Agent Mode are disabled entirely. External file downloads are blocked, and code running in Canvas loses internet access. Additionally, integrated tools such as finance and shopping agents are turned off, and image generation as well as image display within responses are also disabled.
However, core functionalities such as memory, file uploads, chat sharing, and training-related settings remain unaffected. OpenAI clarified that Lockdown Mode is not intended for everyday users but is especially useful for professionals, enterprises, and institutions dealing with sensitive or high-risk data environments. The feature is being rolled out across ChatGPT Free, Go, Plus, Pro, and self-serve business accounts. Users can activate it through the Security section in the app or website settings under Advanced Security options.
