OpenAI announced Lockdown Mode on June 6, 2026, a setting designed to reduce the chance that sensitive data is shared through prompt injection attacks. The mode disables live web browsing, the retrieval and display of web images, deep research, and agent mode. Users can still generate images while the mode is active.
OpenAI stated that even with Lockdown Mode enabled, ChatGPT could remain vulnerable to prompt injections that appear in cached web content or in an uploaded file. @techcrunch reported that the company acknowledged such injections could still affect the behavior or accuracy of a response. The stated goal is to lower the likelihood that sensitive data gets shared during those interactions.
OpenAI said Lockdown Mode is not intended for everyone. It is designed for people and organizations that handle sensitive data and want stricter protection from data exfiltration risks related to prompt injection. The company is currently rolling the feature out to self-serve ChatGPT Business accounts and eligible personal accounts.
